2019-07-02PR ld/24709 [arm] linker crash and assertion failure with CMSEChristophe Lyon2-1/+31
As discussed in the PR, we do not support the case where CMSE stubs are inserted too far from their destination. This would require an intermediate long-branch stub, which is tricky in this context. Instead of crashing, this patch emit an error message and exits. 2019-07-02 Christophe Lyon <christophe.lyon@linaro.org> * bfd/elf32-arm.c (CMSE_STUB_NAME): New define.

2019-07-02Ensure that debug information is retained for ARMv8-M security functions.Srinath Parvathaneni2-0/+25
Consider a file containing only Armv8-M secure entry functions. This file is compiled and linked with "-march=armv8-m.main -mfloat-abi=hard -mfpu=fpv5-sp-d16 -mcmse -static --specs=rdimon.specs -Wl,--section-start,.gnu.sgstubs=0x190000 -ffunction-sections -fdata-sections -Wl,--gc-sections -g" options to generate an executable. The executable generated does not contain any debug information of these secure entry functions even though it contains secure entry functions in the .text section. This patch fixes this problem.

2019-06-28Plugin target handlingAlan Modra6-26/+37
This patch fixes failures with LTO on mingw32 targets. Since git commit 7cf7fcc83c all possible targets (minus binary) are matched in bfd_check_format_matches rather than lower priority targets being excluded once a higher priority target matches. During linking that results in the ld/plugin.c plugin_object_p function being called with the input file xvec set to plugin_vec, which means plugin_get_ir_dummy_bfd doesn't see the real format of the file (pe-i386). It defaults to the output format instead, which happens to be pei-i386, and this wrong choice persists for the dummy bfd. pei-i386 isn't recognised as a valid linker input file. So, omit recognizing a plugin object in bfd_check_format_matches when some other object format matches, and make sure those other object formats are checked first. * format.c (bfd_check_format_matches): Don't match plugin target if another target matches. Expand comment. * targets.c (_bfd_target_vector): Move plugin_vec after all other non-corefile targets, outside !SELECT_VECS. * config.bfd: Don't handle targ=plugin here. * configure.ac: Don't add plugin to enable_targets or handle in target loop setting selvecs and other target vars. * configure: Regenerate.

2019-06-23PR24704, Internal error building skiboot for powerpc64-linux-gnuAlan Modra2-16/+25
While the skiboot linker script bears some culpability in this PR, it's also true that the GOT indirect to GOT relative optimisation for 16-bit offsets isn't safe. At least, it isn't safe to remove the GOT entry based on distance between the GOT pointer and symbol calculated from the preliminary layout. So this patch removes that optimisation, and reduces the range allowed for 32-bit and 34-bit offsets. PR 24704 bfd/ * elf64-ppc.c (R_PPC64_GOT16_DS): Don't set has_gotrel. (ppc64_elf_edit_toc): Don't remove R_PPC64_GOT16_DS got entries.

The testcase in the PR had a e_shstrndx section of type SHT_GROUP. hdr->contents were initialized by setup_group rather than being read from the file, thus last byte was not zero and string dereference ran off the end of the buffer.

2019-06-19PowerPC64 notoc callsAlan Modra2-3/+9
Calls from functions that don't have a valid toc pointer in r2 (these calls are marked with _NOTOC relocs) to functions that require r2 valid must go via the callee global entry point. This patch corrects the condition the linker was using to detect functions that require r2 to be valid. Values of both zero and one in st_other local entry bits mean a function doesn't care about r2. * elf64-ppc.c (ppc64_elf_inline_plt): Correct st_other test for functions that require r2 valid to use local entry. (ppc64_elf_size_stubs, ppc64_elf_relocate_section): Likewise.
