2020-02-13plugin: Search bfd-plugins directories only onceH.J. Lu2-39/+50
try_load_plugin is updated to take either plugin name or plugin entry. load_plugin is updated to search bfd-plugins directories first to build a list of plugins and call try_load_plugin with each plugin on the list. When --plugin is used, the plugin list only has one entry. * plugin.c (try_load_plugin): Make plugin_list_iter an argument and use it if it isn't NULL. Remove has_plugin_p argument. Add a build_list_p argument. Don't search plugin_list. Short circuit when building the plugin list. (has_plugin): Renamed to has_plugin_list. (bfd_plugin_set_plugin): Don't set has_plugin. (bfd_plugin_specified_p): Check plugin_list instead. (build_plugin_list): New function. (load_plugin): Call build_plugin_list and use plugin_list.

2020-02-10MSP430: Enable relaxation of jump instructions to hard-coded pcrel offsetsJozef Lawrynowicz2-11/+65
This patch fixes execution failures which occur when the BR in a sequence such as: J<cond> 1f BR 1: is relaxed to a JMP, and the pc-relative offset for the destination of the J<cond> instruction is hard-coded to be 2 words ahead of the instruction. The hard-coded offset will cause execution to jump 1 word ahead of where it should actually go. Instead we now detect the hard-coded offset is one we inserted earlier, and invert the condition, allowing us to remove the BR entirely. bfd/ChangeLog: 2020-02-10 Jozef Lawrynowicz <jozef.l@mittosystems.com> * elf32-msp430.c (msp430_elf_relax_section): Before relaxing a branch, check if previous instruction matches a conditional jump inserted earlier.

2020-02-04Minor fix for R_PPC_VLE_ADDR20Alan Modra2-1/+6
It is incorrect to "continue" in the ppc_elf_relocate_section reloc processing loop except when editing or deleting relocs. The normal loop processing arranges to write the relocs if shuffling them over a deleted entry. Deleting only happens for debug sections currently and those sections won't contain R_PPC_VLE_ADDR20 relocs, so this patch doesn't fix a bug that would trigger with any normal object file. * elf32-ppc.c (ppc_elf_relocate_section): After applying R_PPC_VLE_ADDR20, goto copy_reloc.

2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu4-6/+33
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.

2020-01-31OOM in setup_groupAlan Modra2-3/+10
We alloc, seek and read using section sizes in object files. Fuzzed objects can have silly sizes, but that's OK if the system supports memory over-commit. The read fails because we hit EOF and that usually results in a graceful exit. But if we memset before the read then the invalid size results in attempting to write to a huge number of memory pages, and an eventual Out Of Memory after probably swapping like crazy. So don't memset. There really isn't a need to clear the section contents anyway. All bytes are written with a good object file by the read and following loop converting section index in target order to ELF section header pointer, and the only untidy bytes are the 4 bytes past the group flags when pointers are 8 bytes. Those don't matter but the patch clears them for anyone poking around in a debugger. On error paths it's as good to free section contents as it is to clear them. Noticed when looking at PR4110 fourth test case. PR 4110 * elf.c (setup_group): Don't clear entire section contents, just the padding after group flags. Release alloc'd memory after a seek or read failure.

These are produced by MSVC when the '/Brepro' flag is used. To quote from the PE specification [1]: "The presence of an entry of type IMAGE_DEBUG_TYPE_REPRO indicates the PE file is built in a way to achieve determinism or reproducibility. If the input does not change, the output PE file is guaranteed to be bit-for-bit identical no matter when or where the PE is produced. Various date/time stamp fields in the PE file are filled with part or all the bits from a calculated hash value that uses PE file content as input, and therefore no longer represent the actual date and time when a PE file or related specific data within the PE is produced.

IMAGE_DEBUG_TYPE_REPRO is defined in the latest version of the PE specification [1]. The others are defined in Windows SDK headers and/or reported by DUMPBIN.

2020-01-30Bugfixes for pe_print_debugdata()Jon Turney2-3/+10
Use a separate iteration variable for inner loop (:blush:). This generally prevented any debug directory entries after a IMAGE_DEBUG_TYPE_CODEVIEW entry from being reported. Don't leak the memory allocated for the section containing the debug directory. bfd/ChangeLog: 2020-01-16 Jon Turney <jon.turney@dronecode.org.uk> * peXXigen.c (pe_print_debugdata): Fix the iteration variable for inner loop. Fix a memory leak.

2020-01-27RISC-V: Fix gdbserver problem with handling arch strings.Jim Wilson2-1/+23
Maciej reported a problem found by his RISC-V gdbserver port. warning: while parsing target description (at line 4): Target description specified unknown architecture "riscv:rv64id" warning: Could not load XML target description; ignoring We only have two arches defined, riscv:rv32 and riscv:rv64. Both bfd and gdb are creating arch strings that have extension letters added to the base architecture. The bfd_default_scan function requires an exact match, so these strings fail to map to a bfd_arch. I think we should ignore the extension letters in a RISC-V specific scan function. bfd/ * cpu-riscv.c (riscv_scan): New. (N): Change bfd_default_scan to riscv_scan.

2020-01-24RISC-V: Minor cleanup for s extension support.Jim Wilson2-5/+9
Looking at older versions of the patch, I confirmed that the odd comment I referred to earlier was indeed from the removal of the sx support. It also explains an oddly formatted switch statement. This patch fixes both minor problems. bfd/ * elfxx-riscv.c (riscv_get_prefix_class): Format s case like others. (riscv_parse_prefixed_ext): Fix s extension comment and reword to avoid over long line.
