2016-03-09Fix v850 bfd arch info printable namesPedro Alves1-0/+7
Currently, it's not possible to manually set some of the v850 archs in gdb: (gdb) set architecture v850<TAB> v850 (using old gcc ABI) v850-rh850 v850e v850e (using old gcc ABI) v850e1 [...] (gdb) set architecture v850 (using old gcc ABI) Ambiguous item "v850 (using old gcc ABI)". The problem is that "set architecture" is a GDB "enum command", and GDB only considers an enum value to be the string up until the first space. So writing "v850 (using old gcc ABI)" is the same as writing "v850", and then that's not an unambiguous arch printable name prefix. v850 is actually the only arch that has spaces in its printable name. One can conveniently see that with e.g.: (gdb) set max-completions unlimited (gdb) complete set architecture ... Rather than hack GDB into accepting this somehow, make v850 arch printable names more like the printable names of the other archs, and put the abi variant in the "machine" part, after a ':'. We now get: (gdb) set architecture v850<TAB> v850:old-gcc-abi v850:rh850 v850e v850e1 v850e1:old-gcc-abi v850e2 v850e2:old-gcc-abi [...] And now "set architecture v850:old-gcc-abi" works as expected. I ran the binutils/gas/ld testsuites, and found no regressions. I don't have a cross compiler handy, but I ran the gdb tests anyway, which covers at least some snoke testing. I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got broken with the previous 2012 change, since I hacked v850_rh850.sc to output "v850" and ld failed to grok it. I think it only works if the old GCC ABI is the configured v850 default ABI. That's now fixed by changing to use explicit v850:old-gcc-abi. Also, this actually "fixes" an existing GDB test, which isn't likewise expecting spaces in arch names, when GDB is configured for --target=v850: (gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures bfd/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * cpu-v850.c (N): Append ":old-gcc-abi" instead of " (using old gcc ABI)" to printable name. * cpu-v850_rh850.c (bfd_v850_rh850_arch): Use "v850:rh850" instead of "v850-rh850" as printable name. ld/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * scripttempl/v850.sc: Use "v850:old-gcc-abi" as OUTPUT_ARCH. * scripttempl/v850_rh850.sc: Use "v850:rh850" as OUTPUT_ARCH.

2016-02-26Optimize x86 GOT32X/GOTPCRELX relocationsH.J. Lu1-0/+15
R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations retrieve the symbol address via its GOT slot. If the symbol address is known at the link-time, we can use it directly by changing instruction encoding. Indirect branch can only be converted to PC relative direct branch. MOV can be changed to LEA or encoded differently with signed address. The subset of binary operations can be encoded only with signed address. If undefined weak symbol is resolved to zero link-time, we can use it as address. Zero addresss can't used with PC relative direct branch when PIC is true since the current PC is unknown. In 64-bit, 32-bit relocation for PC relatiave direct branch to zero may also overflow. If this optimization causes relocation overflow, --no-relax can be used to work around it. bfd/ PR ld/19609 * elf32-i386.c (elf_i386_convert_load): Convert to R_386_32 for load with locally bound symbols if PIC is false or there is no base register.

2016-02-26[x86] Resolve non-PIC undefweak symbols in executableH.J. Lu1-0/+61
For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

2016-02-16Fix BFD format matching for x86_64-w64-mingw32 -m32 LTO.Joseph Myers1-0/+7
In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit 4a07dc81356ed8728e204e9aabeb256703c59aef), Kwok fixed a problem with the template used for a dummy BFD for an IR file for LTO on MinGW, where the input and output formats are not the same. A problem, however, remains in the case of linking for x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity between the pe-i386 and pei-i386 formats. An object (pe-i386) with plugin data is being tested by the linker to see what formats match. The default format initially set by the linker when bfd_check_format_matches is called is pei-i386 (as that's the output format from the linker script), which does not match, so the function goes on to the loop over possible BFD vectors. The pe-i386 vector matches, as it should. One other vector matches: the plugin vector. bfd_check_format_matches tests a vector for matching by temporarily modifying the BFD object to use that vector then using _bfd_check_format on it. So the BFD object is temporarily using plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which succeeds, having created a BFD based on link_info.output_bfd (because srctemplate is the BFD temporarily using plugin_vec, even after Kwok's patch link_info.output_bfd is all that's available to base the dummy BFD on). So we end up with a match from the plugin vector which uses the pei-i386 vector even though the pei-i386 vector itself does not match the input object. (In the i686-mingw32 case, as opposed to this multilib case, pe-i386 is the default BFD target, which would short-circuit that logic.) There are two cases of the linker handling inputs with a plugin: they may be inputs that are also accepted by some non-plugin BFD format, as here, or they may be a format that would not be recognized at all, as with some tests in the ld testsuite. In the former case, there is no need for BFD to accept the objects using the plugin vector, as the linker has its own logic to allow plugins to claim objects accepted by some other BFD vector. Thus, this patch arranges for the plugin vector to have the lowest match priority, and for the priority from that vector to be used in the relevant case (the attempted match to the plugin vector results in TEMP pointing to the pei-i386 vector). Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as well as verifying that it fixes the observed LTO issue for x86_64-w64-mingw32. * plugin.c (plugin_vec): Set match priority to 255. * format.c (bfd_check_format_matches) [BFD_SUPPORTS_PLUGINS]: When matching against the plugin vector, take priority from there not from TEMP.

2016-02-02Store estimated istrances in compressed_sizeH.J. Lu1-0/+6
elf_x86_64_convert_load is very time consuming since it is called on each input section and has a loop over input text sections to estimate the branch distrance. We can store the estimated distrances in the compressed_size field of the output section, which is only used to decompress the compressed input section. Before the patch, linking clang 3.9 takes 52 seconds. After the patch, it only takes 2.5 seconds. PR ld/19542 * elf64-x86-64.c (elf_x86_64_convert_load): Store the estimated distrances in the compressed_size field of the output section.
2016-02-02PowerPC64 ELFv2 entry codeAlan Modra1-0/+5
This tightens the condition under which ld optimizes PIC entry code to non-PIC. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Further restrict ELFv2 entry optimization. gold/ * powerpc.cc (relocate): Further restrict ELFv2 entry optimization.
2016-02-02Clear HAS_RELOC if there are no relocationsH.J. Lu1-0/+6
The HAS_RELOC bit should be cleared when relocations are removed from relocatable files. bfd/ PR binutils/19547 * elf.c (assign_section_numbers): Clear HAS_RELOC if there are no relocations in relocatable files. binutils/ PR binutils/19547 * testsuite/binutils-all/objcopy.exp (objcopy_test_without_global_symbol): New proc.
