Alan Modra	660df28acf	Prefer object over notype symbols when disassembling Changing objdump disassembly output like this always requires some testsuite changes, with the avr and x64_64 changes simply due to picking up better symbols, the whole point of the patch. The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols to STT_OBJECT, which objdump now chooses in preference to script symbols. The problem is that objdump looks at the first symbol in the section being disassembled, and if object type, just dumps out bytes rather than disassembling. This results in new failures: FAIL: JAL overflow 2 FAIL: undefined weak symbol overflow FAIL: undefined weak symbol overflow (n32) FAIL: undefined weak symbol overflow (n64) So for mips-sgi-irix function symbols really do need to be function type. I fixed a few more than just the required minimum to avoid the above test fails. binutils/ * objdump.c (compare_section): New static var. (compare_symbols): Sort by current section only.

Andrew Burgess	4762fe621e	binutils/gas/riscv: Add DWARF register numbers for CSRs This commit gives DWARF register numbers to the RISC-V CSRs inline with the RISC-V ELF specification here: https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md The CSRs are defined being numbered from 4096 to 8191. This adds support to the assembler, required in order to reference CSRs in, for example .cfi directives. I have then extended dwarf.c in order to support printing CSR names in the dumped DWARF output. As the CSR name space is quite large and only sparsely populated, I have provided a new function to perform RISC-V DWARF register name lookup which uses a switch statement rather than the table base approach that other architectures use. Any CSR that does not have a known name will return a name based on 'csr%d' with the %d being replaced by the offset of the CSR from 4096. gas/ChangeLog: * config/tc-riscv.c (tc_riscv_regname_to_dw2regnum): Lookup CSR names too. * testsuite/gas/riscv/csr-dw-regnums.d: New file. * testsuite/gas/riscv/csr-dw-regnums.s: New file. binutils/ChangeLog: * dwarf.c (regname_internal_riscv): New function.

Andrew Burgess	d9acf70759	binutils: Be more forgiving of targets with large numbers of registers Currently if a target has a large ( > 1024 ) number of registers then we get a warning when dumping the DWARF whenever a register over the 1024 limit is referenced, this occurs in dwarf.c:frame_need_space. This check was initially introduced to guard against corrupted DWARF referencing stupidly large numbers of registers. The frame_need_space function already has a check in place so that, if a target specifies a set of known DWARF register names then we must only reference a register within this set, it is only after this check that we check for the 1024 limit. What this means is that if a target DOES NOT define a set of known register names and if we reference more than 1024 registers frame_need_space will give a warning. If a target DOES define a set of known registers and there are more than 1024 defined registers, and we try to reference a register beyond 1024 we will again get an error. This second case feels wrong to me. My thinking is that if a target defines a set of registers then it is not unreasonable to assume the tools can cope with that number of registers. And so, if the target defines 2000 named DWARF registers, frame_need_space should allow access to all of these registers. If a target does not define a set of named registers then the 1024 limit should remain. This is pretty arbitrary, but we do need to have some limit in place I think, so for now that seems as good as any. This is an entirely theoretical fix - there are no targets that define such large numbers of registers, but while experimenting with adding support for RISC-V CSRs I ran into this issue and felt like it was a good improvement. binutils/ChangeLog: * dwarf.c (frame_need_space): Compare dwarf_regnames_count against 0, and only warn about large numbers of registers if the number is more than the dwarf_regnames_count.

Alan Modra	e19511a60c	PR273, SOM size -A The SOM backend creates BFD sections for "spaces", and "sub-spaces". "sub-spaces" are what we normally think of as a section, "spaces" aggregate "sub-spaces". Thus it does not really make sense to include "spaces" for size -A since that would double count total size. It so happens that real sections ought to have at least one of the ALLOC and HAS_CONTENTS flags set, so this patch excludes "spaces" but excluding BFD sections with no flags set. PR 273 * size.c (sysv_internal_sizer, sysv_internal_printer): Exclude sections with no flag bits set. * testsuite/binutils-all/size.exp: Allow $CODE$ as a text section.	7 years ago

Alan Modra	dd68a12bc4	PR25191, internal error in _bfd_elf_set_section_contents This PR copies a fuzzed PE input file to ELF output, in the process confusing the ELF backend by copying COFF-only section flags to the output. SEC_COFF_SHARED has the same value as SEC_ELF_COMPRESS. One approach to fixing this problem is of course not to reuse flag bits, but we've run out. So this patch only copies section flags that are in the bfd_applicable_section_flags set when changing the flavour of the output file. PR 25191 * objcopy.c (is_nondebug_keep_contents_section): Use bfd_get_flavour. (copy_object): Likewise. (setup_section): Likewise. If flavour of input and output files differ, restrict section flags to the intersection of input and output bfd_applicable_section_flags.	7 years ago
