2017-07-23Correct eh_frame info for __glink_PLTresolveAlan Modra4-3/+15
My PPC64_OPT_LOCALENTRY patch of June 1, git commit f378ab099d, and the later gold change, git commit 7ee7ff7015, added an insn in __glink_PLTresolve which needs a corresponding adjustment in the eh_frame info for asynchronous exceptions to unwind correctly. It would have been OK for both ABIs to use +5 for the advance before restore of LR, since we can put the DW_CFA_restore_extended on any insn after the actual restore and before the r12/r0 copy is clobbered, but it's slightly better to delay as much as possible. There are then more addresses where fewer CFA program insns are executed. bfd/ * elf64-ppc.c (ppc64_elf_size_stubs): Correct advance to restore of LR. gold/ * powerpc.cc (glink_eh_frame_fde_64v2): Correct advance to restore of LR.

2017-07-22gdb.python/py-unwind: Disable stack protectionSimon Marchi2-1/+11
[I made some typo fixes but forgot to amend my commit before sending the patch, hence this v2.] I see the following failure on Ubuntu 16.04's gcc 5.4.0: Running /home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.python/py-unwind.exp ... FAIL: gdb.python/py-unwind.exp: continue to breakpoint: break backtrace-broken FAIL: gdb.python/py-unwind.exp: Backtrace restored by unwinder (pattern 1) The problem is that the test expects a very particular stack layout. When stack protection is enabled, it adds a canary value which looks like an additional local variable. This makes the test complain about a bad stack layout and fail. The simple solution is to disable stack protection for that test using -fno-stack-protector. I checked older compilers (gcc 4.4, clang 3.5) and they support that flag, so I don't think it's necessary to probe for whether the compiler supports it. Maybe a better solution would be to change the test to make it cope with different stack layouts (perhaps it could save addresses of stuff in some global variables which GDB/the unwinder would read). I'll go with the simple solution for now though. gdb/testsuite/ChangeLog: * gdb.python/py-unwind.exp: Disable stack protection when building test file.

2017-07-20Make language_def O(1)Pedro Alves18-226/+184
Profiling GDB with the rest of series applied, I saw calls to language_def showing up high in some runs. The problem is that language_def is O(N) currently, since walk the languages vector each time to find the matching language_defn. IMO, the add_language mechanism is pointless, because "enum language" implies the core of GDB needs to know about all languages anyway. So simply make the languages vector array be an array where each element's index is the corresponding enum language enumerator. Note that "local_language_defn" is gone along the way. It's just a copy of "auto", so the new code simply maps one to the other. One fewer place to update when we need to change the language vector... Also, a while ago the output of "set language" was made out of order as side effect of some other change. While I was at it, I made them sorted again. gdb/ChangeLog: 2017-07-20 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Make extern.

This test is using "set language ada" expecting that to cause GDB to do Ada symbol name matching. That won't work when GDB uses the symbol's language to decide which symbol matching algorithm to use, because the test's symbols are C symbols.

2017-07-19LD/testsuite: Add 2**4 section alignment FILL script statement testMaciej W. Rozycki7-8/+97
Complement commit ffe54b3798db ("Pad sections according to current script FILL.") and add a FILL script statement test for targets that impose the minimum alignment of more than 2**2 for the `.text' section. These targets include IA-64 targets, MIPS targets other than bare-metal ELF and VxWorks, TILE-Gx targets, TILEPro targets and X86-64 PE targets. Use the `notarget' tag for configuration triplets that are incompatible with the new test, but are supported by the existing FILL test, and `xfail' for ones that have issues due to section alignment or padding with both tests. Make a complementary change to the existing FILL test, removing the following test issues: arm-epoc-pe -FAIL: ld-scripts/fill mips-elf -XPASS: ld-scripts/fill mips-img-elf -XPASS: ld-scripts/fill mips-mti-elf -XPASS: ld-scripts/fill mips-sde-elf -XPASS: ld-scripts/fill mips-vxworks -XPASS: ld-scripts/fill mipsel-elf -XPASS: ld-scripts/fill mipsel-img-elf -XPASS: ld-scripts/fill mipsel-mti-elf -XPASS: ld-scripts/fill mipsel-vxworks -XPASS: ld-scripts/fill mipsisa32-elf -XPASS: ld-scripts/fill mipsisa32el-elf -XPASS: ld-scripts/fill mipsisa64-elf -XPASS: ld-scripts/fill mipsisa64el-elf -XPASS: ld-scripts/fill tilegx-linux -FAIL: ld-scripts/fill tilepro-elf -FAIL: ld-scripts/fill tx39-elf -XPASS: ld-scripts/fill ld/ * testsuite/ld-scripts/fill.d: Adjust `xfail' entries.

2017-07-18LD/testsuite: Conditionalize the placement of `.got' in GNU_RELROMaciej W. Rozycki2-1/+24
Complement commit d345186d0535 ("Check if GNU_RELRO segment is is generated") and exclude the presence of a `.got' section from implying the creation of a GNU_RELRO segment for targets which place the section along with small data, and therefore as it stands cannot have the section assigned to GNU_RELRO. This is because we currently only support a single GNU_RELRO segment and we place it at the beginning of regular data which is then separated from small data by read-write data. Currently the list of such targets consists of Alpha, Linux HPPA, NetBSD HPPA, OpenBSD HPPA, Meta, MIPS, Nios II, OpenRISC 1000, RISC-V, SH and X86-64, as determined by examining default linker scripts produced in a `--enable-targets=all' build for those that have DATA_SEGMENT_RELRO_END set and `.got' placed beyond. These targets do not set NO_SMALL_DATA or DATA_GOT in their respective files in ld/emulparams/*, hovever checking for the absence of these settings on its own is not very feasible due to the structure of these files and the lack of support for GNU_RELRO by some targets in the first place. Add a separate control for `.got.plt' which does get placed in GNU_RELRO on MIPS targets even though `.got' does not. ld/ * testsuite/ld-elf/binutils.exp (binutils_test): Make the expectation for `.got' in GNU_RELRO segment target-specific. Handle `.got.plt' separately.
