Yao Qi	f4985dba0f	Use disassemble.c:disassembler select rs6000 disassembler Nowadays, rs6000 disassembler is selected in different ways in opcodes and gdb, opcodes: case bfd_arch_rs6000: if (mach == bfd_mach_ppc_620) disassemble = print_insn_big_powerpc; else disassemble = print_insn_rs6000; break; gdb: if (arch == bfd_arch_rs6000) set_gdbarch_print_insn (gdbarch, print_insn_rs6000); else set_gdbarch_print_insn (gdbarch, gdb_print_insn_powerpc); I am not sure which one is the right one. However, such selection should be done in one place instead of two. gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> * rs6000-tdep.c (gdb_print_insn_powerpc): Remove.

Yao Qi	f532ab9438	Use disassemble.c:disassembler select h8300 disassembler opcodes/disassble.c:disassembler select h8300 disassembler like this, if (mach == bfd_mach_h8300h \|\| mach == bfd_mach_h8300hn) disassemble = print_insn_h8300h; else if (mach == bfd_mach_h8300s \|\| mach == bfd_mach_h8300sn \|\| mach == bfd_mach_h8300sx \|\| mach == bfd_mach_h8300sxn) disassemble = print_insn_h8300s; else disassemble = print_insn_h8300; which is the same as what gdb/h8300-tdpe.c does, switch (info.bfd_arch_info->mach) { case bfd_mach_h8300: ... set_gdbarch_print_insn (gdbarch, print_insn_h8300); case bfd_mach_h8300h: case bfd_mach_h8300hn: ... set_gdbarch_print_insn (gdbarch, print_insn_h8300h); case bfd_mach_h8300s: case bfd_mach_h8300sn: ... set_gdbarch_print_insn (gdbarch, print_insn_h8300s); so we can leave disassble.c:disassembler doing the selection. gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> * h8300-tdep.c (h8300_gdbarch_init): Don't call set_gdbarch_print_insn.	9 years ago
Yao Qi	39503f8242	Delegate opcodes to select disassembler in GDB This patch changes GDB to use disassembler selected by opcodes in default, so that we don't have to duplicate the selection logic again in GDB side. For example, gdb/score-tdep.c has static int score_print_insn (bfd_vma memaddr, struct disassemble_info info) { if (info->endian == BFD_ENDIAN_BIG) return print_insn_big_score (memaddr, info); else return print_insn_little_score (memaddr, info); } and opcodes/disassemble.c has the same logic, case bfd_arch_score: if (big) disassemble = print_insn_big_score; else disassemble = print_insn_little_score; This patch removes the logic in GDB and calls opcodes/disassemble.c:disassembler in default to select disassembler. gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> alpha-tdep.c (alpha_gdbarch_init): Don't call set_gdbarch_print_insn. * arc-tdep.c (arc_gdbarch_init): Likewise. * arch-utils.c: include dis-asm.h.

Yao Qi	003ca0fd22	Refactor disassembler selection Nowadays, opcodes/disassemble.c:disassembler selects the proper disassembler according to ABFD only. However, it actually selects disassemblers according to arch, mach, endianess, and abfd. This patch adds them to the parameters of disassembler, so that its caller can still select disassemblers in case that abfd is NULL (a typical case in GDB).

John Baldwin	d489d81d09	Cleanups to FreeBSD/mips native register operations. Compare against the "raw" PC register number instead of the cooked register number when determining if a register was handled by PT_GETREGS. Previously the register fetch/store operations only tried PT_GETREGS to fetch any individual register. The result was that fetching or storing an individual register not covered by PT_GETREGS (such as floating point registers) did not work. While here, remove an early exit to simplify the code flow from the PT_GETREGS / PT_SETREGS case, and add a getfpregs_supplies similar to getregs_supplies to describe the registers supplied by PT_GETFPREGS and PT_SETFPREGS. gdb/ChangeLog: * mips-fbsd-nat.c (getregs_supplies): Fix upper bound comparison.

Andrew Burgess	176efed15c	gdb: Document vMustReplyEmpty remote packet Add mention of the vMustReplyEmpty to the remote serial protocol documentation. It is important that this packet be treated in the same fashion as any other unknown 'v' packet, and I have tried to reflect this in the description of the packet, it is not simply the case that we _must_ return the empty string for this packet. As the intention is that we should treat this packet as unknown then an argument could be made that we should not document it, however, for someone implementing a gdbserver from scratch, seeing an undocumented packet arrive from gdb is confusing, and will probably cause them to have to read the code in order to check how this packet should be handled, which is not ideal. gdb/doc/ChangeLog: * gdb.texinfo (Packets): Document vMustReplyEmpty packet.	9 years ago

Tom Tromey	43cc5389bc	Use watchpoint's language when re-parsing expression PR rust/21484 notes that watch -location does not work with Rust: (gdb) watch -location a syntax error in expression, near `) 0x00007fffffffe0f4'. update_watchpoint tries to tell gdb that the new expression it creates has C syntax: /* The above expression is in C. / b->language = language_c; However, update_watchpoint doesn't actually use this language when re-parsing the expression. Originally I was going to fix this by saving and restoring the language in update_watchpoint, but this regressed gdb.dlang/watch-loc.exp, because the constructed expression actually has D syntax (specifically the name is not parseable by C). Next I looked at directly constructing an expression, and not relying on the parser at all; but it seemed to me that upon a re-set, we'd want to reparse the type, and there is no existing API to do this correctly. So, in the end I made a hook to let each language choose what expression to use. I made all the languages other than Rust use the C expression, because that is the status quo ante. However, this is probably not truly correct. After this patch, at least, it is easy to correct by someone who knows the language(s) in question. Regtested by the buildbot.

Maciej W. Rozycki	e5713223cb	MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count' Revert parts of commit `fee24f1c5b` ("objdump improvements for mips elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and make the `->reloc_count' member of `struct bfd_section' hold the actual number of internal relocations stored in its `->relocation' vector. To do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count' to the actual number of internal relocations retrieved and discard `mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc' and their corresponding target macros. Contrary to the description of `mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes generic relocation processing code happy and satisfies the "merge notes section" binutils test case. Add extra binutils test cases to expand the coverage of the generic "merge notes section" test case, now passing with the n64 ABI, across the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in target configuration, and also to verify correctness of the relocations produced. Conversely, do not provide any additional test cases for the original issue addressed with the commit referred: - objdump would display only 1/3 of the total number of relocations, because it used the external relocation count, but each external relocation is brought in as 3 internal relocations. as n64 ABI relocation processing with `objdump -r' and `objdump -R' is already widely covered across the GAS and LD test suites. bfd/ * elf64-mips.c (mips_elf64_canonicalize_reloc): Remove prototype and function.

Vladimir Mezentsev	1933fd8ee0	gdb: fix TYPE_CODE_ARRAY handling in sparc targets gdb has a special type (TYPE_CODE_ARRAY) to support the gcc extension (https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html). TYPE_CODE_ARRAY is handled incorrectly for both (32- and 64-bit) modes on Sparc machines. Tested on sparc64-linux-gnu and sparc-solaris (32- and 64-bit mode). 6 tests ( from gdb/testsuite/gdb.base/gnu_vector.exp) failed on sparc64-Linux and on sparc-Solaris in 32- and 64-bit mode. Now all these tests passed. gdb/testsuite/gdb.base/gnu_vector.exp has 117 different cases for small (and not small) arrays and structures.

Alan Modra	eb026f09eb	garbage collect debug sections when no alloc sections are kept The pr20882 testcase fails on a number of targets that add attribute or note sections to object files, and the default linker script says those sections should be kept.

The assumption is that debug sections are describing code and data that will become part of the final image in memory. * elflink.c (_bfd_elf_gc_mark_extra_sections): Don't keep debug and special sections when no non-note alloc sections in an object are kept.	9 years ago
