opcodes/riscv: add disassembler options support to libopcodes In preparation for the next commit, which will add GDB support for RISC-V disassembler options, this commit restructures how the disassembler options are managed within libopcodes. The implementation provided here is based on this mailing list patch which was never committed: https://sourceware.org/pipermail/binutils/2021-January/114944.html which in turn took inspiration from the MIPS implementation of the same feature. The biggest changes from the original mailing list post are: 1. The GDB changes have been split into a separate patch, and 2. The `riscv_option_args_privspec` variable, which held the valid priv-spec values is now gone, instead we use the `riscv_priv_specs` array from bfd/cpu-riscv.c instead.

opcodes: Fix RPATH not being set for dynamic libbfd dependency If built as a shared library, libopcodes has a load-time dependency on libbfd, which is recorded in the dynamic section, however without a corresponding RPATH entry for the directory to find libbfd in. This causes loading to fail whenever libbfd is only pulled by libopcodes indirectly and libbfd has been installed in a directory that is not in the dynamic loader's search path. It does not happen with the programs included with binutils or GDB, because they all also pull libbfd when using libopcodes, but it can happen with external software, e.g.: $ gdbserver --help gdbserver: error while loading shared libraries: libbfd-[...].so: cannot open shared object file: No such file or directory $ (not our `gdbserver'). Indirect dynamic dependencies are handled by libtool automatically by adding RPATH entries as required, however our setup for libopcodes prevents this from happening by linking in libbfd with an explicit file reference sneaked through to the linker directly behind libtool's back via the `-Wl' linker command-line option rather than via `-l' combined with a suitable library search path specified via `-L', as it would be usually the case, or just referring to the relevant .la file in a fully libtool-enabled configuration such as ours. According to an observation in the discussion back in 2007[1][2][3] that has led to the current arrangement it is to prevent libtool from picking up the wrong version of libbfd. It does not appear to be needed though, not at least with our current libtool incarnation, as directly referring `libbfd.la' does exactly what it should, as previously suggested[4], and with no link-time reference to the installation directory other than to set RPATH. Uninstalled version of libopcodes has libbfd's build-time location prepended to RPATH too, as also expected. Use a direct reference to `libbfd.la' then, making the load error quoted above go away. Alternatively `-L' and `-l' could be used to the same effect, but it seems an unnecessary complication and just another way to circumvent rather than making use of libtool.

riscv: print .2byte or .4byte before an unknown instruction encoding When the RISC-V disassembler encounters an unknown instruction, it currently just prints the value of the bytes, like this: Dump of assembler code for function custom_insn: 0x00010132 <+0>: addi sp,sp,-16 0x00010134 <+2>: sw s0,12(sp) 0x00010136 <+4>: addi s0,sp,16 0x00010138 <+6>: 0x52018b 0x0001013c <+10>: 0x9c45 My proposal, in this patch, is to change the behaviour to this: Dump of assembler code for function custom_insn: 0x00010132 <+0>: addi sp,sp,-16 0x00010134 <+2>: sw s0,12(sp) 0x00010136 <+4>: addi s0,sp,16 0x00010138 <+6>: .4byte 0x52018b 0x0001013c <+10>: .2byte 0x9c45 Adding the .4byte and .2byte opcodes. The benefit that I see here is that in the patched version of the tools, the disassembler output can be fed back into the assembler and it should assemble to the same binary format. Before the patch, the disassembler output is invalid assembly. I've started a RISC-V specific test file under binutils so that I can add a test for this change. binutils/ChangeLog: * testsuite/binutils-all/riscv/riscv.exp: New file. * testsuite/binutils-all/riscv/unknown.d: New file. * testsuite/binutils-all/riscv/unknown.s: New file. opcodes/ChangeLog: * riscv-dis.c (riscv_disassemble_insn): Print a .%dbyte opcode before an unknown instruction, '%d' is replaced with the instruction length.

opcodes: make use of __builtin_popcount when available This commit provides a small performance improvement when starting up CGEN based disassemblers by making use of __builtin_popcount. The #if check used in this commit was copied from bfd/elf32-arm.c where __builtin_popcount is also used. I ran into this code while investigating some GDB tests that would occasionally timeout. One of the reason these tests were having problems is that the m16c and m32c disassemblers take so long to initialise themselves. Speeding up count_decodable_bits helps, but is not a total solution. Still, this felt like an easy win which added minimal extra complexity, so I figure its worth doing. opcodes/ChangeLog: * cgen-dis.c (count_decodable_bits): Use __builtin_popcount when available.

arc: Construct disassembler options dynamically The idea of this change is simple: Populate a data structure, namely "disasm_option_and_arg_t" from "include/dis-asm.h", to encompass the disassembly options and their possible arguments. This will make it easier to manage or extend those options by adapting entries in a data structure, "arc_options". There will be lesser need to hard-code the options in the code itself. Moreover, ARC GDB will use this population function, "disassembler_options_arc ()", to enable the "set disassembler-option" for ARC targets. The gdb change will be in a separate patch though. The changes in this patch can be divided into: 1) Introduction of "disassembler_options_arc ()" that will return a "disasm_option_and_arg_t" structure representing the disassembly options and their likely arguments. 2) New data type "arc_options_arg_t" and new data "arc_options". These are the internals for keeping track of options and arguments entries that can easily be extended. 3) To print the options, the "print_arc_disassembler_options ()" has been adjusted to use this dynamically built structure instead of having them hard-coded inside. To see this in effect, one can look into the output of: $ ./binutils/objdump --help ...

MIPS/opcodes: Reorder legacy COP0, COP2, COP3 opcode instructions Group legacy instructions using the COP0, COP2, COP3 opcodes together and by their coprocessor number, and move them towards the end of the opcode table. No functional change. With the addition of explicit ISA exclusions this is maybe not strictly necessary anymore as the individual legacy instructions are not supposed to match ISA levels or CPU implementations that have discarded them or replaced with a new instruction each, but let's not have them scattered randomly across blocks of unrelated instruction sets where someone chose to put them previously. Perhaps they could be put back in alphabetical order in the main instruction block, but let's leave it for another occasion. opcodes/ * mips-opc.c (mips_builtin_opcodes): Reorder legacy COP0, COP2, COP3 opcode instructions.

MIPS/opcodes: Accurately record coprocessor opcode CPU/ISA membership Adjust opcode table entries for coprocessor instructions that have been removed from certain ISA levels or CPU implementations as follows: - remove CP0 memory access instructions from MIPS II up as the LWC0 and SWC0 opcodes have been reused for the LL and SC instructions respectively[1]; strictly speaking LWC0 and SWC0 have never really been defined in the first place[2], but let's keep them for now in case an odd implementation did, - remove CP0 branch instructions from MIPS IV[3] and MIPS32[4] up, as they have been removed as from those ISAs, - remove CP0 control register move instructions from MIPS32 up, as they have been removed as from that ISA[5], - remove the RFE instruction from MIPS III[6] and MIPS32[7] up, as it has been removed as from those ISAs in favour to ERET, - remove CP2 instructions from Vr5400 CPUs as their encodings have been reused for the multimedia instruction set extensions[8] and no CP2 registers exist[9], - remove CP3 memory access instructions from MIPS III up as coprocessor 3 has been removed as from that ISA[10][11] and from MIPS32 up as the LWC3 opcode has been reused for the PREF instruction and consequently all the four memory access instructions removed from the ISA (though the COP3 opcode has been retained)[12]. Update the testsuite accordingly.

MIPS/opcodes: Remove DMFC3 and DMTC3 instructions Coprocessor 3 has been removed from the MIPS ISA as from MIPS III[1][2] with the LDC3 and SDC3 instructions having been replaced with LD and SD instructions respectively and therefore the doubleword move instructions from and to that coprocessor have never materialized (for 32-bit ISAs coprocessor 3 has likewise been removed as from MIPS32r2[3]). Remove the DMFC3 and DMTC3 instructions from the opcode table then to avoid confusion.

It is because the "rfe" opcode table entry was incorrectly moved behind the catch-all generic "c0" entry for CP0 instructions, causing output like: 00: 42000010 c0 0x10 to be produced rather than: 00: 42000010 rfe even for ISA levels that do include the RFE instruction.

MIPS/opcodes: Do not use CP0 register names for control registers The CP0 control register set has never been defined, however encodings for the CFC0 and CTC0 instructions remained available for implementers up until the MIPS32 ISA declared them invalid and causing the Reserved Instruction exception[1]. Therefore we handle them for both assembly and disassembly, however in the latter case the names of CP0 registers from the regular set are incorrectly printed if named registers are requested. This is because we do not define separate operand classes for coprocessor regular and control registers respectively, which means the disassembler has no way to tell the two cases apart. Consequently nonsensical disassembly is produced like: cfc0 v0,c0_random Later the MIPSr5 ISA reused the encodings for XPA ASE MFHC0 and MTHC0 instructions[2] although it failed to document them in the relevant opcode table until MIPSr6 only. Correct the issue then by defining a new register class, OP_REG_CONTROL, and corresponding operand codes, `g' and `y' for the two positions in the machine instruction a control register operand can take. Adjust the test cases affected accordingly. While at it swap the regular MIPS opcode table "cfc0" and "ctc0" entries with each other so that they come in the alphabetical order.

MIPS/opcodes: Free up redundant `g' operand code In the operand handling rewrite made for the MIPS disassembler with commit ab90248154ba ("Add structures to describe MIPS operands"), <https://sourceware.org/ml/binutils/2013-07/msg00135.html>, the `g' operand code has become redundant for the regular MIPS instruction set by duplicating the OP_REG_COPRO semantics of the `G' operand code. Later commit 351cdf24d223 ("Implement O32 FPXX, FP64 and FP64A ABI extensions") converted the CTTC1 instruction from the `g' to the `G' operand code, but still left a few instructions behind.

microMIPS/opcodes: Refer FPRs rather than FCRs with DMTC1 The DMTC1 instruction operates on a floating-point general register as its second operand, however in the disassembly of the microMIPS encoding a floating-point control register is shown instead. This is due to an incorrect ordering of the two "dmtc1" entries in the opcode table, which gives precedence to one using the `G' aka coprocessor format over one using the `S' or floating-point register format. The coprocessor format, or OP_REG_COPRO, is used so that GAS supports referring to FPRs by their numbers in assembly, such as $0, $1, etc. however in the case of CP1/FPU it is also used by the disassembler to decode those numbers to the names of corresponding control registers. This in turn causes nonsensical disassembly such as: dmtc1 a1,c1_fir in a reference to $f0. It has been like this ever since microMIPS ISA support has been added. Correct the ordering of the two entries then by swapping them with each other, making disassembly output consistent with the regular MIPS DMTC1 instruction as well all the remaining CP1 move instructions.

arm: Fix bugs with MVE vmov from two GPRs to vector lanes The initial problem I wanted to fix here is that GAS was rejecting MVE instructions such as: vmov q3[2], q3[0], r2, r2 with: Error: General purpose registers may not be the same -- `vmov q3[2],q3[0],r2,r2' which is incorrect; such instructions are valid. Note that for moves in the other direction, e.g.: vmov r2, r2, q3[2], q3[0] GAS is correct in rejecting this as it does not make sense to move both lanes into the same register (the Arm ARM says this is CONSTRAINED UNPREDICTABLE). After fixing this issue, I added assembly/disassembly tests for these vmovs. This revealed several disassembly issues, including incorrectly marking the moves into vector lanes as UNPREDICTABLE, and disassembling many of the vmovs as vector loads. These are now fixed. gas/ChangeLog: * config/tc-arm.c (do_mve_mov): Only reject vmov if we're moving into the same GPR twice. * testsuite/gas/arm/mve-vmov-bad-2.l: Tweak error message. * testsuite/gas/arm/mve-vmov-3.d: New test. * testsuite/gas/arm/mve-vmov-3.s: New test. opcodes/ChangeLog: * arm-dis.c (mve_opcodes): Fix disassembly of MVE_VMOV2_GP_TO_VEC_LANE when idx == 1.

x86: optimize LEA Over the years I've seen a number of instances where people used lea (%reg1), %reg2 or lea symbol, %reg despite the same thing being expressable via MOV. Since additionally LEA often has restrictions towards the ports it can be issued to, while MOV typically gets dealt with simply by register renaming, transform to MOV when possible (without growing opcode size and without altering involved relocation types). Note that for Mach-O the new 64-bit testcases would fail (for BFD_RELOC_X86_64_32S not having a representation), and hence get skipped there.

AArch64: Fix Atomic LD64/ST64 classification. Patch 1: Fix diagnostics for exclusive load/stores and reclassify Armv8.7-A ST/LD64 Atomics. Following upstream pointing out some inconsistencies in diagnostics, https://sourceware.org/pipermail/binutils/2021-February/115356.html attached is a patch set that fixes the issues. I believe a combination of two patches mainly contributed to these bugs: https://sourceware.org/pipermail/binutils/2020-November/113961.html https://sourceware.org/pipermail/binutils/2018-June/103322.html A summary of what this patch set fixes: For instructions STXR w0,x2,[x0] STLXR w0,x2,[x0] The warning we emit currently is misleading: Warning: unpredictable: identical transfer and status registers --`stlxr w0,x2,[x0]' Warning: unpredictable: identical transfer and status registers --`stxr w0,x2,[x0]' it ought to be: Warning: unpredictable: identical base and status registers --`stlxr w0,x2,[x0]' Warning: unpredictable: identical base and status registers --`stxr w0,x2,[x0]' For instructions: ldaxp x0,x0,[x0] ldxp x0,x0,[x0] The warning we emit is incorrect Warning: unpredictable: identical transfer and status registers --`ldaxp x0,x0,[x0]' Warning: unpredictable: identical transfer and status registers --`ldxp x0,x0,[x0]' it ought to be: Warning: unpredictable load of register pair -- `ldaxp x0,x0,[x0]' Warning: unpredictable load of register pair -- `ldxp x0,x0,[x0]' For instructions stlxp w0, x2, x2, [x0] stxp w0, x2, x2, [x0] We don't emit any warning when it ought to be: Warning: unpredictable: identical base and status registers --`stlxp w0,x2,x2,[x0]' Warning: unpredictable: identical base and status registers --`stxp w0,x2,x2,[x0]' For instructions: st64bv x0, x2, [x0] st64bv x2, x0, [x0] We incorrectly warn when its not necessary. This is because we classify them incorrectly as ldstexcl when it should be lse_atomics in the opcode table. The incorrect classification makes it pick up the warnings from warning on exclusive load/stores. Patch 2: Reclassify Armv8.7-A ST/LD64 Atomics. This patch reclassifies ST64B{V,V0}, LD64B as lse_atomics rather than ldstexcl according to their encoding class as specified in the architecture. This also has the fortunate side-effect of spurious unpredictable warnings getting eliminated. For eg. For instruction: st64bv x0, x2, [x0] We incorrectly warn when its not necessary: Warning: unpredictable: identical transfer and status registers --`st64bv x0,x2,[x0]' This is because we classify them incorrectly as ldstexcl when it should be lse_atomics in the opcode table. The incorrect classification makes it pick up the warnings from warning on exclusive load/stores. This patch fixes it by reclassifying it and no warnings are issued for this instruction. opcodes/ChangeLog: 2021-04-09 Tejas Belagod <tejas.belagod@arm.com> * aarch64-tbl.h (struct aarch64_opcode aarch64_opcode_table): Reclassify LD64/ST64 instructions to lse_atomic instead of ldstexcl.

Note that for certain SSE2AVX templates this results in benign attribute changes: - LDMXCSR and STMXCSR: NoAVX gets set, - MOVMSKPS, PMOVMSKB, PEXTR{B,W} (register destination), and PINSR{B,W} (register source): IgnoreSize and NoRex64 get set, - CVT{DQ,PS}2PD, CVTSD2SS, MOVMSKPD, MOVDDUP, PMOV{S,Z}X{BW,WD,DQ}, and ROUNDSD: NoRex64 gets set, - CVTSS2SD, INSERTPS, PEXTRW (memory destination), PINSRW (memory source), and PMOV{S,Z}X{BD,WQ,BQ}: IgnoreSize gets set. Similarly the "normal" (non-SSE2AVX) - non-64-bit CVTS{I,S}2SD forms get NoRex64 set, - CMP{EQ,ORD,NEQ,UNORD}{P,S}{S,D} forms get C set, all again in a benign way. The remaining differences in the generated table are due to re-ordering of entries in the course of being folded into templates.

x86: undo Prefix_0X<nn> use in opcode table The table entries are more natural to read (and slightly shorter) when the prefixes, like is the case for VEX/XOP/EVEX-encoded entries, are specified as part of the opcode. This is particularly noticable for side-by-side legacy and SSE2AVX entries. An implication is that we now need to use "unsigned long long" for the initially parsed opcode in i386-gen. I don't expect this to be an issue.

x86: shrink some struct insn_template fields Now that all base opcodes are only at most 2 bytes in size, shrink its template field to just as much. By also shrinking extension_opcode and operands to just what they really need, we can free up an entire 32-bit slot (plus 4 left bits past the bitfields themselves). At present this alters sizeof(struct insn_template) only for 32-bit builds. In 64-bit builds it instead leaves a padding hole that will allow to buffer future growth of other fields (opcode_modifier, cpu_flags, operand_types[]).

TRUE/FALSE simplification There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value.

x86: fix AMD Zen3 insns For INVLPGB the operand count was wrong (besides %edx there's also %ecx which is an input to the insn). In this case I see little sense in retaining the bogus 2-operand template. Plus swapping of the operands wasn't properly suppressed for Intel syntax. For PVALIDATE, RMPADJUST, and RMPUPDATE bogus single operand templates were specified. These get retained, as the address operand is the only one really needed to expressed non-default address size, but only for compatibility reasons. Proper multi-operand insn get introduced and the testcases get adjusted / extended accordingly. While at it also drop the redundant definition of __amd64__ - we already have x86_64 defined (or not) to distinguish 64-bit and non-64-bit cases.

x86: derive opcode length from opcode value In the majority of cases we can easily determine the length from the encoding, irrespective of whether a prefix is specified there as well. We further don't even need to record the value in the table entries, as it's easy enough to determine it (without any guesswork, unless an insn with major opcode 00 appeared that requires a 2nd opcode byte to be specified explicitly) when installing the chosen template for further processing. Should an encoding appear which - has a major opcode byte of 66, F3, or F2, - requires a 2nd opcode byte to be specified explicitly, - doesn't have a mandatory prefix we'd need to convert all templates presently encoding a mandatory prefix this way to the Prefix_0X<nn> model to eliminate the respective guessing i386-gen does.

x86/Intel: correct AVX512 S/G disassembly Commit 6ff00b5e12e7 ("x86/Intel: correct permitted operand sizes for AVX512 scatter/gather") brought the assembler side of AVX512 S/G insn handling in line with AVX2's, but the disassembler side was forgotten. This has the benefit of - allowing to fold a number of table entries, - rendering a few #define-s and enumerators unused.

x86: re-arrange enumerator and table entry order Some of the enumerators have ended up misplaced under the general current ordering scheme. Move them (and their table entries) around accordingly. Add a couple of blank lines as separators when close to code being touched anyway. Also drop the odd 0F from 0FXOP (there's no "0f" involved there anywhere) infixes where the respective enum gets played with anyway.

x86: correct decoding of nop/reserved space (0f18 ... 0x1f) All encodings not used in this range are (reserved) NOPs. Hence their decoding should be fully consistent. For this to work the PREFIX_IGNORED logic needs slightly extending, such that the attribute will also - have an effect when used inside prefix_table[], yet without always falling back to using slot 0, - cause prefixes marked as ignored while decoding through prefix_table[] to no longer be considered decoded, when encountered in a subsequent decoding step. In adjacent code also drop meaningless PREFIX_OPCODE.

RISC-V: Add bfd/cpu-riscv.h to support all spec versions controlling. Make the opcode/riscv-opc.c and include/opcode/riscv.h tidy, move the spec versions stuff to bfd/cpu-riscv.h. Also move the csr stuff and ext_version_table to gas/config/tc-riscv.c for internal use. To avoid too many repeated code, define general RISCV_GET_SPEC_NAME/SPEC_CLASS macros.

read_leb128 overflow checking There is a tiny error left in dwarf.c:read_leb128 after Nick fixed the signed overflow problem in code I wrote. It's to do with sleb128 values that have unnecessary excess bytes. For example, -1 is represented as 0x7f, the most efficient encoding, but also as 0xff,0x7f or 0xff,0xff,0x7f and so on. None of these sequences overflow any size signed value, but read_leb128 will report an overflow given enough excess bytes. This patch fixes that problem, and since the proper test for signed values with excess bytes can easily be adapted to also test a sleb byte with just some bits that overflow the result, I changed the code to not use signed right shifts. (The C standard ISO/IEC 9899:1999 6.5.7 says signed right shifts of negative values have an implementation defined value. A long time ago I even used a C compiler for a certain microprocessor that always did unsigned right shifts. Mind you, it is very unlikely to be compiling binutils with such a compiler.) bfd/ * wasm-module.c: Guard include of limits.h. (CHAR_BIT): Provide backup define.

x86: CVTPI2PD has special behavior CVTPI2PD with a memory operand, unlike CVTPI2PS, doesn't engage MMX logic. Therefore it - has a proper AVX equivalent (CVTDQ2PD) and hence can be subject to SSE2AVX translation and SSE checking, - should not record MMX use in the respective ELF note.

bfd, opcodes, libctf: support --with-included-gettext Right now, these libraries hardwire -L../intl -lintl on a few fixed platforms, which works fine on those platforms but on other platforms leads to shared libraries that lack libintl_* symbols when configured --with-included-gettext, and/or static libraries that contain libintl as *another* static library. If we instead use the LIBINTL variable defined in ../intl/config.intl, this gives us the right thing on all three classes of platform (gettext in libc, gettext in system libintl, gettext in ../intl/libintl.a).. This also means we can rip out some Darwin-specific machinery from configure.ac and also simplify the Cygwin side. This also means that the libctf testsuite (and other places that include libbfd, libopcodes or libctf) don't need to grow libintl dependencies just on account of those libraries (though they still need such dependencies if they themselves use gettext machinery). bfd/ChangeLog 2021-02-03 Nick Alcock <nick.alcock@oracle.com> * configure.ac (SHARED_LIBADD): Remove explicit -lintl population in favour of LIBINTL. * configure: Regenerated. libctf/ChangeLog 2021-02-02 Nick Alcock <nick.alcock@oracle.com> * configure.ac (CTF_LIBADD): Remove explicit -lintl population in favour of LIBINTL. * Makefile.am (libctf_nobfd_la_LIBADD): No longer explicitly include $(LIBINTL).

RISC-V: Add pause hint instruction. Add support for the pause hint instruction, as specified in the Zihintpause extension. The pause instruction is encoded as a special form of a memory fence (which is available as part of the base instruction set). The chosen encoding does not mandate any particular memory ordering and therefore is a true hint. bfd/ * elfxx-riscv.c (riscv_std_z_ext_strtab): Added zihintpause. gas/ * config/tc-riscv.c (riscv_multi_subset_supports): Added INSN_CLASS_ZIHINTPAUSE. * testsuite/gas/riscv/pause.d: New testcase.

RISC-V: Support riscv bitmanip frozen ZBA/ZBB/ZBC instructions (v0.93). In fact rev8/orc.b/zext.h are the aliases of grevi/gorci/pack[w], so we should update them to INSN_ALIAS when we have supported their true instruction in the future. Though we still use the [MATCH|MAKS]_[GREVI|GORCI|PACK|PACKW] to encode them. Besides, the orc.b has the same encoding both in rv32 and rv64, so we just keep one of them in the opcode table. This patch is implemented according to the following link, https://github.com/riscv/riscv-bitmanip/pull/101 2021-01-07 Claire Xenia Wolf <claire@symbioticeda.com> Jim Wilson <jimw@sifive.com> Andrew Waterman <andrew@sifive.com> Maxim Blinov <maxim.blinov@embecosm.com> Kito Cheng <kito.cheng@sifive.com> Nelson Chu <nelson.chu@sifive.com> bfd/ * elfxx-riscv.c (riscv_std_z_ext_strtab): Added zba, zbb and zbc. gas/ * config/tc-riscv.c (riscv_multi_subset_supports): Handle INSN_CLASS_ZB*.

Update year range in copyright notice of binutils files The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
