gdb/riscv: Add read_description method for riscv_linux_nat_target Adds riscv_linux_nat_target::read_description method to find a suitable target description for the native linux target we are running on. Currently this will supply a suitably sized set of x-registers, and will probe the kernel to see if the f-registers are readable. If they are readable then we currently assume that the f-registers are the same size as the x-registers as I don't know of a good way to probe the f-register length. This will obviously need fixing in future. As of Linux 4.19 there is no ptrace support for reading the f-registers, this should appear in 4.20, so right now we only return target descriptions without f-registers. gdb/ChangeLog: * riscv-linux-nat.c: Add 'inferior.h' and 'target-descriptions.h' header files. (riscv_linux_nat_target::read_description): New method.

Fix riscv-linux native gdb build failure. The linux kernel uses NT_PRFPREG. Glibc before BZ 14890 defines NT_FPREGSET. After it defines both. Avoid glibc version dependency by using the gdb header file instead of the glibc header file, and the macro name that gdb defines which is NT_FPREGSET. gdb/ * riscv-linux-nat.c: Include elf/common.h instead of elf.h. (riscv_linux_nat_target::fetch_registers): Use NT_FPREGSET instead of NT_PRFPREG. (riscv_linux_nat_target::store_registers): Likewise.

RISC-V/Linux/native: Determine FLEN dynamically Fix RISC-V native Linux support to handle a 64-bit FPU (FLEN == 64) with both RV32 and RV64 systems, which is a part of the current Linux ABI for hard-float systems, rather than assuming that (FLEN == XLEN) in target description determination and that (FLEN == 64) in register access. We can do better however and not rely on any particular value of FLEN and probe for it dynamically, by observing that the PTRACE_GETREGSET ptrace(2) call will only accept an exact regset size, and that will reflect FLEN. Therefore iterate over the call in target description determination with a geometrically increasing regset size until a match is marked by a successful ptrace(2) call completion or we run beyond the maximum size we can support. Update register accessors accordingly, using FLEN determined to size the buffer used for NT_PRSTATUS requests and then to exchange data with the regcache. Also handle a glibc bug where ELF_NFPREG is defined in terms of NFPREG, however NFPREG is nowhere defined. gdb/ * riscv-linux-nat.c [!NFPREG] (NFPREG): New macro. (supply_fpregset_regnum, fill_fpregset): Handle regset buffer offsets according to FLEN determined. (riscv_linux_nat_target::read_description): Determine FLEN dynamically.

RISC-V/Linux/native: Determine FLEN dynamically Fix RISC-V native Linux support to handle a 64-bit FPU (FLEN == 64) with both RV32 and RV64 systems, which is a part of the current Linux ABI for hard-float systems, rather than assuming that (FLEN == XLEN) in target description determination and that (FLEN == 64) in register access. We can do better however and not rely on any particular value of FLEN and probe for it dynamically, by observing that the PTRACE_GETREGSET ptrace(2) call will only accept an exact regset size, and that will reflect FLEN. Therefore iterate over the call in target description determination with a geometrically increasing regset size until a match is marked by a successful ptrace(2) call completion or we run beyond the maximum size we can support. Update register accessors accordingly, using FLEN determined to size the buffer used for NT_PRSTATUS requests and then to exchange data with the regcache. Also handle a glibc bug where ELF_NFPREG is defined in terms of NFPREG, however NFPREG is nowhere defined. gdb/ * riscv-linux-nat.c [!NFPREG] (NFPREG): New macro.

gdb/riscv: Add read_description method for riscv_linux_nat_target Adds riscv_linux_nat_target::read_description method to find a suitable target description for the native linux target we are running on. Currently this will supply a suitably sized set of x-registers, and will probe the kernel to see if the f-registers are readable. If they are readable then we currently assume that the f-registers are the same size as the x-registers as I don't know of a good way to probe the f-register length. This will obviously need fixing in future. As of Linux 4.19 there is no ptrace support for reading the f-registers, this should appear in 4.20, so right now we only return target descriptions without f-registers. gdb/ChangeLog: * riscv-linux-nat.c: Add 'inferior.h' and 'target-descriptions.h' header files.

gdb/riscv: Update API for looking up target descriptions In preparation for adding the RISC-V gdbserver, this commit restructures the API for looking up target descriptions. The current API is riscv_create_target_description, which creates a target description from a riscv_gdbarch_features, but also caches the created target descriptions so that for a given features object we always get back the same target description object. This is important for GDB due to the way gdbarch objects are reused. As the same target description is always returned to GDB, and can be returned multiple times, it is returned as a const, however, the current cache actually stores a non-const target description. This is improved in this patch so that the cache holds a const target description. For gdbsever, this caching of the target descriptions is not needed, the gdbserver looks up one target description to describe the target it is actually running on and that is it. Further the gdbserver actually needs to modify the target description that is looked up, so for the gdbsever, returning a const target description is not acceptable. This commit aims to address this by creating two parallel target description APIs, on is the old riscv_create_target_description, however, this no longer performs any caching, and just creates a new target description, and returns it as non-const. The second API is riscv_lookup_target_description, this one performs the caching, and calls riscv_create_target_description to create a target description when needed. In order to make sure the correct API is used in the correct place I have guarded the code using the GDBSERVER define. For GDB the riscv_create_target_description is static, and not generally usable throughout GDB, only the lookup API is global. In gdbserver, the lookup functions, and the cache are not defined or created at all, only the riscv_create_target_description API is available. There should be no user visible changes after this commit. gdb/ChangeLog: * arch/riscv.c (struct riscv_gdbarch_features_hasher): Only define if GDBSERVER is not defined.

gdb: add back declarations for _initialize functions I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c
