DesCGENization of the BPF binutils port

Browse Source 
CGEN is cool, but the BPF architecture is simply too bizarre for it.

The weird way of BPF to handle endianness in instruction encoding, the
weird C-like alternative assembly syntax, the weird abuse of
multi-byte (or infra-byte) instruction fields as opcodes, the unusual
presence of opcodes beyond the first 32-bits of some instructions, are
all examples of what makes it a PITA to continue using CGEN for this
port.  The bpf.cpu file is becoming so complex and so nested with
p-macros that it is very difficult to read, and quite challenging to
update.  Also, every time we are forced to change something in CGEN to
accommodate BPF requirements (which is often) we have to do extensive
testing to make sure we do not break any other target using CGEN.

This is getting un-maintenable.

So I have decided to bite the bullet and revamp/rewrite the port so it
no longer uses CGEN.  Overall, this involved:

* To remove the cpu/bpf.{cpu,opc} descriptions.

* To remove the CGEN generated files.

* To replace the CGEN generated opcodes table with a new hand-written
  opcodes table for BPF.

* To replace the CGEN generated disassembler wih a new disassembler
  that uses the new opcodes.

* To replace the CGEN generated assembler with a new assembler that uses the
  new opcodes.

* To replace the CGEN generated simulator with a new simulator that uses the
  new opcodes. [This is pushed in GDB in another patch.]

* To adapt the build systems to the new situation.

Additionally, this patch introduces some extensions and improvements:

* A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF
  relocation R_BPF_GNU_64_16 are added to the BPF BFD port.  These
  relocations are used for section-relative 16-bit offsets used in
  load/store instructions.

* The disassembler now has support for the "pseudo-c" assembly syntax of
  BPF.  What dialect to use when disassembling is controlled by a command
  line option.

* The disassembler now has support for dumping instruction immediates in
  either octal, hexadecimal or decimal.  The used output base is controlled
  by a new command-line option.

* The GAS BPF test suite has been re-structured and expanded in order to
  test the disassembler pseudoc syntax support.  Minor bugs have been also
  fixed there.  The assembler generic tests that were disabled for bpf-*-*
  targets due to the previous implementation of pseudoc syntax are now
  re-enabled.  Additional tests have been added to test the new features of
  the assembler.  .dump files are no longer used.

* The linker BPF test suite has been adapted to the command line options
  used by the new disassembler.

The result is very satisfactory.  This patchs adds 3448 lines of code
and removes 10542 lines of code.

Tested in:

* Target bpf-unknown-none with 64-bit little-endian host and 32-bit
  little-endian host.

* Target x86-64-linux-gnu with --enable-targets=all

Note that I have not tested in a big-endian host yet.  I will do so
once this lands upstream so I can use the GCC compiler farm.

I have not included ChangeLog entries in this patch: these would be
massive and not very useful, considering this is pretty much a rewrite
of the port.  I beg the indulgence of the global maintainers.

;;;; The ISAs
;; Logically, eBPF comforms a single instruction set featuring two
;; kind of instructions: 64-bit instructions and 128-bit instructions.
;;
;; The 64-bit instructions have the form:
;;
;; code:8 regs:8 offset:16 imm:32
;;
;; Whereas the 128-bit instructions (at the moment there is only one
;; of such instructions, lddw) have the form:
;;
;; code:8 regs:8 offset:16 imm:32 unused:32 imm:32
;;
;; In both formats `regs' is itself composed by two fields:
;;
;; dst:4 src:4
;;
;; The ISA is supposed to be orthogonal to endianness: the endianness
;; of the instruction fields follow the endianness of the host running
;; the eBPF program, and that's all. However, this is not entirely
;; true. The definition of an eBPF code in the Linux kernel is:
;;
;; struct bpf_insn {
;; __u8 code; /* opcode */
;; __u8 dst_reg:4; /* dest register */
;; __u8 src_reg:4; /* source register */
;; __s16 off; /* signed offset */
;; __s32 imm; /* signed immediate constant */
;; };
;;
;; Since the ordering of fields in C bitmaps is defined by the
;; implementation, the impact of endianness in the encoding of eBPF
;; instructions is effectively defined by GCC. In particular, GCC
;; places dst_reg before src_reg in little-endian code, and the other
;; way around in big-endian code.
;;
;; So, in reality, eBPF comprises two instruction sets: one for
;; little-endian with instructions like:
;;
;; code:8 src:4 dst:4 offset:16 imm:32 [unused:32 imm:32]
;;
;; and another for big-endian with instructions like:
;;
;; code:8 dst:4 src:4 offset:16 imm:32 [unused:32 imm:32]
;;
;; where `offset' and the immediate fields are encoded in
;; little-endian and big-endian byte-order, respectively.

Tags:
%% - literal %.
%dr - destination 64-bit register.
%dw - destination 32-bit register.
%sr - source 64-bit register.
%sw - source 32-bit register.
%d32 - 32-bit signed displacement (in 64-bit words minus one.)
%d16 - 16-bit signed displacement (in 64-bit words minus one.)
%o16 - 16-bit signed offset (in bytes.)
%i32 - 32-bit signed immediate.
%I32 - Like %i32.
%i64 - 64-bit signed immediate.
%w - expect zero or more white spaces and print a single space.
%W - expect one or more white spaces and print a single space.
When parsing and printing %o16 and %I32 (but not %i32) an
explicit sign is always expected and included. Therefore, to
denote something like `[%r3 + 10]', please use a template like `[
%sr %o16]' instead of `[ %sr + %o16 ]'.
If %dr, %dw, %sr or %sw are found multiple times in a template,
they refer to the same register, i.e. `%rd = le64 %rd' denotes
`r2 = le64 r2', but not `r2 = le64 r1'.
If %i64 appears in a template then the instruction is 128-bits
long and composed by two consecutive 64-bit instruction words.
A white space character means to expect zero or more white
spaces, and to print no space.
There are two templates defined per instruction, corresponding to
two used different dialects: a "normal" assembly-like syntax and
a "pseudo-c" syntax. Some toolchains support just one of these
dialects. The GNU Toolchain supports both. */

XINFO is a `void *' and not a `disassemble_info *' to not put a requirement

This function is basically just a big switch statement. Earlier versions
used tables to look up the function to use, but
- if the table contains both assembler and disassembler functions then
the disassembler contains much of the assembler and vice-versa,
- there's a lot of inlining possibilities as things grow,
- using a switch statement avoids the function call overhead.
This function could be moved into `print_insn_normal', but keeping it
separate makes clear the interface between `print_insn_normal' and each of
