2020-08-17gas: Fix internal error in S_SET_SEGMENTAlex Coplan5-1/+26
This patch fixes an internal error in GAS when defining a section using a symbol that has already been named but not defined. For a minimal reproducer, try the following input: a=b .sect a The problem is that obj_elf_change_section() happily reuses the symbol "a" created by equals() without clearing the sy_value field: prior to this patch, it just set bsym. This caused a problem when attempting to resolve the section symbol, since resolve_symbol_value() ended up resolving the symbol as if it were the original symbol created by equals(), which ends up leaving the section symbol in the undefined section instead of in section a, hence the call to abort() in S_SET_SEGMENT(). gas/ChangeLog: * config/obj-elf.c (obj_elf_change_section): When repurposing an existing symbol, ensure that we set sy_value as per other (fresh) section symbols. * testsuite/gas/elf/elf.exp: Add new test. * testsuite/gas/elf/section-symbol-redef.d: New test. * testsuite/gas/elf/section-symbol-redef.s: Input for test.

2020-08-06gas: Fix internal error on long local labelsAlex Coplan6-3/+32
Prior to this commit, on an input such as "88888888888:", GAS hits a signed integer overflow and likely an assertion failure. I see: $ echo "88888888888:" | bin/aarch64-none-elf-as {standard input}: Assembler messages: {standard input}:1: Internal error in fb_label_name at ../gas/symbols.c:2049. Please report this bug. To fix this issue, I've taken two steps: 1. Change the type used for processing local labels in read_a_source_file() from int to long, to allow representing more local labels, and also since all uses of this variable (temp) are actually of type long. 2. Detect if we would overflow and bail out with an error message instead of actually overflowing and hitting the assertion in fb_label_name(). gas/ChangeLog: 2020-08-06 Alex Coplan <alex.coplan@arm.com> * read.c (read_a_source_file): Use long for local labels, detect overflow and raise an error for overly-long labels. * testsuite/gas/all/gas.exp: Add local-label-overflow test. * testsuite/gas/all/local-label-overflow.d: New test. * testsuite/gas/all/local-label-overflow.l: Error output. * testsuite/gas/all/local-label-overflow.s: Input.

2020-08-04gas: Make sure .debug_line file table contains a zero filename and dirMark Wielaard2-9/+34
For DWARF5 the zero file list entry in the .debug_line table represents the compile unit main file. It can be set with .file 0 when -gdwarf-5 is given. But since this directive is illegal for older versions, this is almost never set. To make sure it is always set (so DW_AT_name of the compile unit can be set) use file (and dir) 1 if that is defined (otherwise fall back to pwd, to match DW_AT_comp_dir). gas/ChangeLog: * gas/dwarf2dbg.c (out_dir_and_file_list): For DWARF5 emit at least one directory if there is at least one file.

2020-07-30Unify Solaris procfs and largefile handlingRainer Orth5-13/+63
GDB currently doesn't build on 32-bit Solaris: * On Solaris 11.4/x86: In file included from /usr/include/sys/procfs.h:26, from /vol/src/gnu/gdb/hg/master/dist/gdb/i386-sol2-nat.c:24: /usr/include/sys/old_procfs.h:31:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^~~~~ * On Solaris 11.3/x86 there are several more instances of this. The interaction between procfs and large-file support historically has been a royal mess on Solaris: * There are two versions of the procfs interface: ** The old ioctl-based /proc, deprecated and not used any longer in either gdb or binutils. ** The `new' (introduced in Solaris 2.6, 1997) structured /proc. * There are two headers one can possibly include: ** <procfs.h> which only provides the structured /proc, definining _STRUCTURED_PROC=1 and then including ... ** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based /proc, but provides structured /proc if _STRUCTURED_PROC == 1. * procfs and the large-file environment didn't go well together: ** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit compilations when the large-file environment was active (_FILE_OFFSET_BITS == 64). ** In both Solaris 11.4 and Illumos, this restriction was lifted for structured /proc. So one has to be careful always to define _STRUCTURED_PROC=1 when testing for or using <sys/procfs.h> on Solaris. As the errors above show, this isn't always the case in binutils-gdb right now. Also one may need to disable large-file support for 32-bit compilations on Solaris. config/largefile.m4 meant to do this by wrapping the AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because it neglects the _STRUCTURED_PROC part. To make things even worse, since GCC 9 g++ predefines _FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to enable large-file support, this has no effect, breaking the gdb build. This patch addresses all this as follows: * All tests for the <sys/procfs.h> header are made with _STRUCTURED_PROC=1, the definition going into the various config.h files instead of having to make them (and sometimes failing) in the affected sources. * To cope with the g++ predefine of _FILE_OFFSET_BITS=64, -U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had been far easier to have just #undef _FILE_OFFSET_BITS in config.h, but unfortunately such a construct in config.in is commented by config.status irrespective of indentation and whitespace if large-file support is disabled. I found no way around this and putting the #undef in several global headers for bfd, binutils, ld, and gdb seemed way more invasive. * Last, the applicability check in largefile.m4 was modified only to disable largefile support if really needed. To do so, it checks if <sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it doesn't, the disabling only happens if gdb exists in-tree and isn't disabled, otherwise (building binutils from a tarball), there's no conflict. What initially confused me was the check for $plugins here, which originally caused the disabling not to take place. Since AC_PLUGINGS does enable plugin support if <dlfcn.h> exists (which it does on Solaris), the disabling never happened. I could find no explanation why the linker plugin needs large-file support but thought it would be enough if gld and GCC's lto-plugin agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not enough: lto-plugin uses the simple-object interface from libiberty, which includes off_t arguments. So to fully disable large-file support would mean also disabling it in libiberty and its users: gcc and libstdc++-v3. This seems highly undesirable, so I decided to disable the linker plugin instead if large-file support won't work. The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to predefined _FILE_OFFSET_BITS=64). Also regtested on amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4), x86_64-pc-linux-gnu and i686-pc-linux-gnu. config: * largefile.m4 (ACX_LARGEFILE) <sparc-*-solaris*|i?86-*-solaris*>: Check for <sys/procfs.h> incompatilibity with large-file support on Solaris.

2020-07-29MIPS: Make the IRIX naming of local section symbols consistentMaciej W. Rozycki8-0/+93
Make the MIPS/IRIX naming of local section symbols consistent between files produced by generic ELF code and ELF linker code, complementing commit 174fd7f95561 ("New bfd elf hook: force naming of local section symbols"), <https://sourceware.org/ml/binutils/2004-02/msg00072.html>. Local section symbols have no names in the standard ELF gABI, however the lack of a name causes problems with IRIX's MIPSpro linker. To work around the issue we give them names, however we do that in generic ELF code only, based on what the `elf_backend_name_local_section_symbols' hook returns if present. That makes objects created by GAS or `objdump' work correctly, however not ones created by `ld -r'. That would not normally cause issues with IRIX systems using GAS and `objdump' only with the MIPSpro linker, however if GNU LD was used for whatever reason in producing objects later fed to IRIX's MIPSpro linker, then things would break. Modify ELF linker code accordingly then, using the same hook. Adjust the `ld-elf/64ksec-r' test accordingly so that it also accepts a section symbol with a name. Also modify the hook itself so that only actual ET_REL objects have names assigned to local section symbols. Other kinds of ELF files are not ever supposed to be relocated with the MIPSpro linker, so we can afford producing more standard output. Add suitable GAS, LD and `objcopy' test cases to the relevant testsuites to keep these tools consistently verified. This change also fixes: FAIL: objcopy executable (pr25662) across MIPS targets using the IRIX compatibility mode. bfd/ * elflink.c (bfd_elf_final_link): Give local symbols a name if so requested. * elfxx-mips.c (_bfd_mips_elf_name_local_section_symbols): Only return TRUE if making ET_REL output. binutils/ * testsuite/binutils-all/mips/global-local-symtab-sort-o32.d: New test. * testsuite/binutils-all/mips/global-local-symtab-sort-o32t.d: New test. * testsuite/binutils-all/mips/global-local-symtab-sort-n32.d: New test. * testsuite/binutils-all/mips/global-local-symtab-sort-n32t.d: New test. * testsuite/binutils-all/mips/global-local-symtab-sort-n64.d: New test. * testsuite/binutils-all/mips/global-local-symtab-sort-n64t.d: New test. * testsuite/binutils-all/mips/global-local-symtab-final-o32.d: New test. * testsuite/binutils-all/mips/global-local-symtab-final-n32.d: New test. * testsuite/binutils-all/mips/global-local-symtab-final-n64.d: New test. * testsuite/binutils-all/mips/mips.exp: Run the new tests. gas/ * testsuite/gas/mips/global-local-symtab-sort-o32.d: New test. * testsuite/gas/mips/global-local-symtab-sort-o32t.d: New test. * testsuite/gas/mips/global-local-symtab-sort-n32.d: New test. * testsuite/gas/mips/global-local-symtab-sort-n32t.d: New test. * testsuite/gas/mips/global-local-symtab-sort-n64.d: New test. * testsuite/gas/mips/global-local-symtab-sort-n64t.d: New test. * testsuite/gas/mips/mips.exp: Run the new tests. ld/ * testsuite/ld-elf/sec64k.exp: Also accept a section symbol with a name. * testsuite/ld-mips-elf/global-local-symtab-sort-o32.d: New test. * testsuite/ld-mips-elf/global-local-symtab-sort-o32t.d: New test. * testsuite/ld-mips-elf/global-local-symtab-sort-n32.d: New test. * testsuite/ld-mips-elf/global-local-symtab-sort-n32t.d: New test. * testsuite/ld-mips-elf/global-local-symtab-sort-n64.d: New test. * testsuite/ld-mips-elf/global-local-symtab-sort-n64t.d: New test. * testsuite/ld-mips-elf/global-local-symtab-final-o32.d: New test. * testsuite/ld-mips-elf/global-local-symtab-final-n32.d: New test. * testsuite/ld-mips-elf/global-local-symtab-final-n64.d: New test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests.
2020-07-29MIPS/LD: Set symtab's `sh_info' correctly for IRIX emulationsMaciej W. Rozycki8-0/+62
Correct ELF linker code so as to set the `sh_info' value of the static symbol table section according to the section symbols vs other symbols split where required by the selection of the IRIX compatibility mode for MIPS target. Add a `elf_backend_elfsym_local_is_section' hook for that purpose, returning TRUE if it is only STB_LOCAL/STT_SECTION symbols that are to be considered local for the purpose of this split rather than all STB_LOCAL symbols. We do it already in generic ELF code, and have done it since 1993, with the `elf_backend_sym_is_global' hook, affecting GAS and `objcopy', so these tools produce correct ELF output in the IRIX compatibility mode, however if such output is fed as input to `ld -r', then the linker's output is no longer valid for that mode. The relevant changes to generic ELF code are: commit 062189c6eab72c7ba1bab1cf30fdb27d67a7d668 Author: Ian Lance Taylor <ian@airs.com> Date: Thu Nov 18 17:12:47 1993 +0000 and: commit 6e07e54f1b347f885cc6c021c3fd912c79bdaf55 Author: Ian Lance Taylor <ian@airs.com> Date: Thu Jan 6 20:01:42 1994 +0000 (split across two GIT commits likely due to repository conversion peculiarities). The `elf_backend_sym_is_global' hook however operates on BFD rather than ELF symbols, making it unsuitable for the ELF linker as the linker does not convert any symbol tables processed into the BFD format. Converting the hook to operate on ELF symbols would in principle be possible, but it would still require a considerable rewrite of `bfd_elf_final_link' to adapt to the interface. Therefore, especially given that no new use for the IRIX compatibility mode is expected, minimize changes made to the ELF linker code and just add an entirely new hook, and wire it in the o32 and n32 MIPS backends accordingly; the n64 backend never uses the IRIX compatibility mode. Since we have no coverage here at all add suitable GAS, LD and `objcopy' test cases to the relevant testsuites to keep these tools consistently verified. bfd/ * elf-bfd.h (elf_backend_data): Add `elf_backend_elfsym_local_is_section' member. * elfxx-target.h (elf_backend_elfsym_local_is_section): New macro.

2020-07-22MIPS/GAS/testsuite: Fix JALR relocation tests for IRIX targetsMaciej W. Rozycki26-12/+1857
With IRIX targets the JALR hint relocation is not produced for the o32 ABI, where it is considered a GNU extension. Consequently several tests fail as the output produced by GAS fails to match patterns expecting the relocation to be present where appropriate, even though output produced is indeed correct. As the absence of the relocation is expected, fix the tests by providing respective alternative dump patterns with any JALR relocations removed, removing numerous failures with `*-*-irix*' targets: FAIL: MIPS jal-svr4pic (interaptiv-mr2) FAIL: MIPS jal-svr4pic (micromips) FAIL: MIPS jal-svr4pic (mips1) FAIL: MIPS jal-svr4pic (mips2) FAIL: MIPS jal-svr4pic (mips3) FAIL: MIPS jal-svr4pic (mips4) FAIL: MIPS jal-svr4pic (mips5) FAIL: MIPS jal-svr4pic (mips32) FAIL: MIPS jal-svr4pic (mips32r2) FAIL: MIPS jal-svr4pic (mips32r3) FAIL: MIPS jal-svr4pic (mips32r5) FAIL: MIPS jal-svr4pic (mips32r6) FAIL: MIPS jal-svr4pic (mips64) FAIL: MIPS jal-svr4pic (mips64r2) FAIL: MIPS jal-svr4pic (mips64r3) FAIL: MIPS jal-svr4pic (mips64r5) FAIL: MIPS jal-svr4pic (mips64r6) FAIL: MIPS jal-svr4pic (octeon) FAIL: MIPS jal-svr4pic (octeon2) FAIL: MIPS jal-svr4pic (octeon3) FAIL: MIPS jal-svr4pic (octeonp) FAIL: MIPS jal-svr4pic (r3000) FAIL: MIPS jal-svr4pic (r3900) FAIL: MIPS jal-svr4pic (r4000) FAIL: MIPS jal-svr4pic (r5900) FAIL: MIPS jal-svr4pic (sb1) FAIL: MIPS jal-svr4pic (vr5400) FAIL: MIPS jal-svr4pic (xlr) FAIL: MIPS jal-svr4pic noreorder (interaptiv-mr2) FAIL: MIPS jal-svr4pic noreorder (micromips) FAIL: MIPS jal-svr4pic noreorder (mips1) FAIL: MIPS jal-svr4pic noreorder (mips2) FAIL: MIPS jal-svr4pic noreorder (mips3) FAIL: MIPS jal-svr4pic noreorder (mips4) FAIL: MIPS jal-svr4pic noreorder (mips5) FAIL: MIPS jal-svr4pic noreorder (mips32) FAIL: MIPS jal-svr4pic noreorder (mips32r2) FAIL: MIPS jal-svr4pic noreorder (mips32r3) FAIL: MIPS jal-svr4pic noreorder (mips32r5) FAIL: MIPS jal-svr4pic noreorder (mips32r6) FAIL: MIPS jal-svr4pic noreorder (mips64) FAIL: MIPS jal-svr4pic noreorder (mips64r2) FAIL: MIPS jal-svr4pic noreorder (mips64r3) FAIL: MIPS jal-svr4pic noreorder (mips64r5) FAIL: MIPS jal-svr4pic noreorder (mips64r6) FAIL: MIPS jal-svr4pic noreorder (octeon) FAIL: MIPS jal-svr4pic noreorder (octeon2) FAIL: MIPS jal-svr4pic noreorder (octeon3) FAIL: MIPS jal-svr4pic noreorder (octeonp) FAIL: MIPS jal-svr4pic noreorder (r3000) FAIL: MIPS jal-svr4pic noreorder (r3900) FAIL: MIPS jal-svr4pic noreorder (r4000) FAIL: MIPS jal-svr4pic noreorder (r5900) FAIL: MIPS jal-svr4pic noreorder (sb1) FAIL: MIPS jal-svr4pic noreorder (vr5400) FAIL: MIPS jal-svr4pic noreorder (xlr) FAIL: MIPS R3000 jal-xgot FAIL: MIPS -mabi=32 test 2 (SVR4 PIC) FAIL: gas/mips/jalr2 FAIL: Relax microMIPS branches (pic) FAIL: Relax microMIPS branches (insn32 mode, pic) Strictly speaking no MIPSr6 or microMIPS target is supported by IRIX, but GAS supports such configurations on the basis of uniformity, so provide the relevant patterns too rather than excluding the combinations from testing. gas/ * testsuite/gas/mips/jal-svr4pic-irix.d: New file. * testsuite/gas/mips/mips1@jal-svr4pic-irix.d: New file. * testsuite/gas/mips/mipsr6@jal-svr4pic-irix.d: New file. * testsuite/gas/mips/micromips@jal-svr4pic-irix.d: New file. * testsuite/gas/mips/r3000@jal-svr4pic-irix.d: New file. * testsuite/gas/mips/jal-svr4pic-local-irix.d: New file. * testsuite/gas/mips/mips1@jal-svr4pic-local-irix.d: New file. * testsuite/gas/mips/micromips@jal-svr4pic-local-irix.d: New file. * testsuite/gas/mips/r3000@jal-svr4pic-local-irix.d: New file. * testsuite/gas/mips/jal-svr4pic-noreorder-irix.d: New file. * testsuite/gas/mips/mips1@jal-svr4pic-noreorder-irix.d: New file. * testsuite/gas/mips/mipsr6@jal-svr4pic-noreorder-irix.d: New file. * testsuite/gas/mips/micromips@jal-svr4pic-noreorder-irix.d: New file. * testsuite/gas/mips/r3000@jal-svr4pic-noreorder-irix.d: New file. * testsuite/gas/mips/jal-xgot-irix.d: New file. * testsuite/gas/mips/jalr2-irix.d: New file. * testsuite/gas/mips/micromips-branch-relax-insn32-pic-irix.d: New file. * testsuite/gas/mips/micromips-branch-relax-pic-irix.d: New file. * testsuite/gas/mips/mips-abi32-pic2-irix.d: New file. * testsuite/gas/mips/jal-svr4pic-local.d: Don't exclude `*-*-irix*' targets.

At the same time also revert the ELF related part of 99c2d522f7a7 ("x86: Update assembler tests for non-ELF targets") by replacing the construct that's problematic for non-ELF, and by adding the "#pass" patterns to the expected output files to cover for the tail padding generated into COFF output.

PR gas/4572 When / is a comment character, its use as binary "divide" operator needs escaping by a backslash. Besides the scrubber needing to support this (addressed in an earlier change), there are also a few provisions needed in target specific operator handling. As the spec calls for % and * to also be escaped because of being "overloaded", also recognize these, despite the overloading there not really preventing their use as operators in most (%) or all (*) cases, given the way how the rest of the assembler works. To bring source and testsuite in line, also drop the TE_I386AIX part of the respective conditional, as i?86-*-aix* support had been removed a while ago.
