2020-04-02ld: Disable ifunc tests on SolarisRainer Orth2-2/+6
A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86: FAIL: ld-ifunc/ifunc-10-x86-64 FAIL: ld-ifunc/ifunc-11-x86-64 FAIL: ld-ifunc/ifunc-12-x86-64 FAIL: ld-ifunc/ifunc-13-x86-64 FAIL: ld-ifunc/ifunc-14a-x86-64 FAIL: ld-ifunc/ifunc-14b-x86-64 FAIL: ld-ifunc/ifunc-14c-x86-64 FAIL: ld-ifunc/ifunc-14d-x86-64 FAIL: ld-ifunc/ifunc-14e-x86-64 FAIL: ld-ifunc/ifunc-14f-x86-64 FAIL: ld-ifunc/ifunc-15-x86-64 FAIL: ld-ifunc/ifunc-17a-x86-64 FAIL: ld-ifunc/ifunc-17b-x86-64 FAIL: ld-ifunc/ifunc-2-local-x86-64-now FAIL: ld-ifunc/ifunc-2-local-x86-64 FAIL: ld-ifunc/ifunc-2-x86-64-now FAIL: ld-ifunc/ifunc-2-x86-64 FAIL: ld-ifunc/ifunc-20-x86-64 FAIL: ld-ifunc/pr17154-x86-64-now FAIL: ld-ifunc/pr17154-x86-64 For one, the actual error is weird: ./ld-new: target elf64-x86-64 not found failed with: <./ld-new: target elf64-x86-64 not found>, no expected output FAIL: ld-ifunc/ifunc-10-x86-64 although ld -V does report the elf_x86_64 emulation as supported: $ ./ld/ld-new -V GNU ld (GNU Binutils) 2.34.50.20200328 Supported emulations: elf_x86_64_sol2 elf_x86_64 [...] When using ld -m elf_x86_64_sol2 instead, one of the testcases links successfully. However, there's no point in pursuing this: Solaris does not support ifunc, as can be seen in <sys/elf.h>: /* * GNU/Linux specific symbol type not used by Solaris */ #define STT_GNU_IFUNC 10 and never will, given that it has symbol capabilities as solution to effectively the same problem: http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/ Therefore this patch disables ifunc testing on Solaris completely by removing Solaris from binutils/testsuite/lib/binutils-common.exp (supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is in the OS-specific range and conflicts with #define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */ While the comment suggests this might be relocatable without too much problems, the description of mbind (no formal spec AFAICS, just the comment in the binutils patch submission) strongly suggests that this isn't relevant to Solaris at all. Indirectly, clearing supports_gnu_osabi on Solaris disables supports_gnu_unique. Again, Solaris <sys/elf.h> has /* * GNU/Linux specific binding not used by Solaris */ #define STB_GNU_UNIQUE 10 so this seems the right thing to do. Afterwards, one can remove the explicit mentions of *-*-solaris2* in quite a number of (but not all) the ld-ifunc dump file notarget lists. There's one fallout, though: two gas tests now XPASS because they are xfail'ed for !supports_gnu_osabi: XPASS: mbind sections 12 XPASS: mbind section contents 16 XPASS: mbind sections 16 XPASS: mbind section contents 16 To fix that, I've changed #xfail: ![supports_gnu_osabi] to notarget.

2020-03-28Re: Adjust objcopy_testAlan Modra2-4/+9
Last patch didn't manage to xfail spu due to clear_xfail *-*-*elf*. Clearing *-*-*elf* dates back to a time when we had rather a lot more setup_xfail patterns, so limiting it to hppa*-*-*elf*. Also, mips-*-irix ought to have been mips-*-irix* and I'm having second thoughts about xfailing mips and hiding what looks like a problem: If the mips target is supposed to emit names for local section symbols and does so for objcopy, why isn't it doing the same for ld? Also, lots more mips targets would be subject to this test failing. So I'm backing out those xfails and leaving it to someone more knowledgeable about mips. * testsuite/binutils-all/objcopy.exp (objcopy_test): Only clear_xfail hppa*-*-*elf*. Revert mips xfails.
2020-03-28Adjust objcopy_testAlan Modra2-14/+28
xfails spu due to a note section getting a different vma, and some mips targets that give section symbols a name string. I added -p for the executable test in an attempt to fix all the pe target fails, but that doesn't preserve the date/time for some reason. * testsuite/binutils-all/objcopy.exp (objcopy_test): Move xfails from here to calls. Remove "m8*-*-*" entry. Don't xfail tic54x but do xfail spu, mipstx39 and mips-sgi-irix for the executable test. Pass "-p" to objcopy for the executable test.

2020-03-27Re: readelf looping in process_archiveAlan Modra2-2/+7
This patch fixes a leak of qualified_name caused by 4c83662712 and a double free introduced by fd486f32d1. Not breaking out of the loop results in an error: "failed to seek to next archive header". That's slightly better than silently preventing the possibility of endless loops. * readelf.c (process_archive): Don't double free qualified_name.

With the right set of options, the second block of code dealing with padding can see a different section count. So don't use the new count. Since I was editing those lines, I've also changed the code allocating arrays a little. array = malloc (n * sizeof (*array)); for an array of ints is just better than array = malloc (n * sizeof (int)); It's easier to write correctly in the first place and more robust against code changes that might modify the array element type.

In commit 2b44a6a237 (" binutils: doc: make `make clean` clean more things"), I moved the doc build artifacts to MOSTLYCLEANFILES, which made them get removed by "make clean". Because generating binutils.info requires makeinfo, and we do not want to require makeinfo when building from the tarball, binutils.info should not get removed by "make clean" (otherwise, it won't be included in the tarball). And to be consistent with other projects (e.g. ld and gas), we also want to ship the built man pages in the tarball. This patch puts back all these in MAINTAINERCLEANFILES, so that they are bundled in the tarball, and only cleaned if you use "make maintainer-clean".

2020-02-20RISC-V: Support the ISA-dependent CSR checking.Nelson Chu2-1/+6
According to the riscv privilege spec, some CSR are only valid when rv32 or the specific extension is set. We extend the DECLARE_CSR and DECLARE_CSR_ALIAS to record more informaton we need, and then check whether the CSR is valid according to these information. We report warning message when the CSR is invalid, so we have a choice between error and warning by --fatal-warnings option. Also, a --no-warn/-W option is used to turn the warnings off, if people don't want the warnings. gas/ * config/tc-riscv.c (enum riscv_csr_class): New enum. Used to decide whether or not this CSR is legal in the current ISA string. (struct riscv_csr_extra): New structure to hold all extra information of CSR. (riscv_init_csr_hash): New function. According to the DECLARE_CSR and DECLARE_CSR_ALIAS, insert CSR extra information into csr_extra_hash. Call hash_reg_name to insert CSR address into reg_names_hash. (md_begin): Call riscv_init_csr_hashes for each DECLARE_CSR. (reg_csr_lookup_internal, riscv_csr_class_check): New functions. Decide whether the CSR is valid according to the csr_extra_hash. (init_opcode_hash): Update 'if (hash_error != NULL)' as hash_error is not a boolean. This is same as riscv_init_csr_hash, so keep the consistent usage. * testsuite/gas/riscv/csr-dw-regnums.d: Add -march=rv32if option. * testsuite/gas/riscv/priv-reg.d: Add f-ext by -march option. * testsuite/gas/riscv/priv-reg-fail-fext.d: New testcase.

2020-02-19Merge changes from GCC for the config/ directoryAndrew Burgess2-8/+29
GCC's config/ChangeLog since the last time this merge was done (in the binutils-gdb commit 0b4d000cc4e8e77c823) is included at the end of this commit message. It is worth noting that the binutils-gdb commit 301a9420d947da1458 added the file config/debuginfod.m4 which is not present in GCC's config/ directory. This file is preserved, unmodified, after this commit. In order to regenerate all of the configure files, I configured with --enable-maintainer-mode, and built the 'all' target. I then did the same thing on a source tree without this patch, and only committed those files that changed when this patch was added.
