2016-11-16Fix PR20789 - relaxation with negative valued diff relocsSenthil Kumar Selvaraj2-0/+26
Fix issues with diff relocs that have a negative value i.e. sym2 - sym1 where sym2 is lesser than sym1. The assembler generates a diff reloc with symbol as start of section and addend as sym2 offset, and encodes assembly time difference at the reloc offset. The existing relaxation logic adjusts addends if the relaxed insn lies between symbol and addend. That doesn't work for diff relocs where sym2 is less than sym1 *and* the relaxed insn happens to be between sym2 and sym1. Fix the problems by 1. Using signed handling of the difference value (bfd_signed_vma instead of bfd_vma, bfd_{get,set}_signed_xxx instead of bfd_{get,set}_xxx). 2. Not assuming sym2 is bigger than sym1. It instead computes the actual addresses and sets the lower and higher addresses as start and end addresses respectively and then sees if insn is between start and end. 3. Creating a new function elf32_avr_adjust_reloc_if_spans_insn to centralize reloc adjustment, and ensuring diff relocs get adjusted correctly even if their sym + addend doesn't overlap a relaxed insn. It also removes a redundant variable did_pad. It is never set if did_shrink is TRUE, and the code does a early return if did_shrink is FALSE. bfd/ChangeLog 2016-11-15 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/20789 * bfd/elf32-avr.c (elf32_avr_adjust_diff_reloc_value): Do signed manipulation of diff value, and don't assume sym2 is less than sym1.

2016-11-04ld: Allow EXCLUDE_FILE to be used outside of the section listAndrew Burgess15-0/+131
Currently the EXCLUDE_FILE linker script construct can only be used within the input section list, and applied only to the section pattern immediately following the EXCLUDE_FILE. For example: *.o (EXCLUDE_FILE (a.o) .text .rodata) In this case all sections matching '.text' are included from all files matching '*.o' but not from the file 'a.o'. All sections matching '.rodata' are also included from all files matching '*.o' (incluing from 'a.o'). If the user wants to restrict the inclusion of section '.rodata' so that this too is not taken from the file 'a.o' then the above example must be extended like this: *.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata) However, due to the internal grammar of the linker script language the snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called 'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse the input file name snippet '*.o' in the above examples. As a result of this pattern reuse within the linker script grammar then the following is also a valid linker script construct: EXCLUDE_FILE (a.o) *.o (.text .rodata) However, though the linker accepts this without complaint the EXCLUDE_FILE part is silently ignored and has no effect. This commit takes this last example and makes it a useful, valid, construct. The last example now means to include sections '.text' and '.rodata' from all files matching '*.o' except for the file 'a.o'. If the list of input sections is long, and the user knows that the file exclusion applies across the list then the second form might be a clearer alternative to replicating the EXCLUDE_FILE construct. I've added a set of tests for EXCLUDE_FILE to the linker, including tests for the new functionality. ld/ChangeLog: * ldlang.h (struct lang_wild_statement_struct): Add exclude_name_list field. * ldlang.c (walk_wild_file_in_exclude_list): New function.

2016-11-04ld: Create test object files based on source file nameAndrew Burgess5-7/+25
When creating object files during testing, base the name of the object file on the name of the source file, rather than using dump0.o, dump1.o, etc. There's a few places where we have multiple source files with the same name but in different directories, in these cases, even after this change, we still add a numerical suffix to make the object file names unique. So if we have 'foo/src.s' and 'bar/src.s', we will create object files 'src.o' and 'src1.o'. Update the few tests that hard code the object file name into the expected test results. ld/ChangeLog: * testsuite/lib/ld-lib.exp (run_dump_test): Use object file names based on the original source file name. * testsuite/ld-discard/extern.d: Update object file names. * testsuite/ld-discard/start.d: Likewise. * testsuite/ld-discard/static.d: Likewise. * testsuite/ld-elf/orphan-8.map: Likewise.

2016-10-11Always descend into output section statements in lang_do_assignmentsAlan Modra2-4/+2
See https://sourceware.org/ml/binutils/2016-07/msg00091.html This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols that ought to remain global. The difficulty with always descending into output section statements is that symbols defined by the script in such statements don't have a bfd section when lang_do_assignments runs early in the link process. There are two approaches to curing this problem. Either we can create the bfd section early, or we can use a special section. This patch takes the latter approach and uses bfd_und_section. (Creating bfd sections early results in changed output section order, and thus lots of testsuite failures. You can't create all output sections early to ensure proper ordering as KEEP then stops empty sections from being stripped.) The wrinkle with this approach is that some code that runs at gc-sections time needs to be made aware of the odd defined symbols using bfd_und_section. bfd/ * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Handle symbols defined temporarily with bfd_und_section. * elflink.c (_bfd_elf_gc_keep): Don't set SEC_KEEP for bfd_und_section. * elfxx-mips.c (mips_elf_local_pic_function_p): Exclude defined symbols with bfd_und_section. ld/ * ldlang.c (lang_do_assignments_1): Descend into output section statements that do not yet have bfd sections.

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker.

2016-09-21[AArch64] Add SVE condition codesRichard Sandiford2-8/+8
SVE defines new names for existing NZCV conditions, to reflect the result of instructions like PTEST. This patch adds support for these names. The patch also adds comments to the disassembly output to show the alternative names of a condition code. For example: cinv x0, x1, cc becomes: cinv x0, x1, cc // cc = lo, ul, last and: b.cc f0 <...> becomes: b.cc f0 <...> // b.lo, b.ul, b.last Doing this for the SVE names follows the practice recommended by the SVE specification and is definitely useful when reading SVE code.

2016-09-06Fix PR ld/20545 - relaxation bugs in avr backendSenthil Kumar Selvaraj4-0/+43
Prior to the patch, addends for relocs were being adjusted even if they went beyond an alignment boundary. This is wrong - to preserve alignment constraints, the relaxation logic adds as many padding bytes at the alignment boundary as was deleted, so addends beyond the boundary should not be adjusted. avr-prop-7.s reproduces this scenario. Also, prior to this patch, the relaxation logic assumed that the addr parameter pointed to the middle of the instruction to be deleted, and that addr - count would therefore be the shrinked instruction's address. This is true when actually shrinking instructions. The alignment constraints handling logic also invokes the same logic though, with addr as the starting offset of padding bytes and with count as the number of bytes to be deleted. Calculating the shrinked insn's address as addr - count is obviously wrong in this case - that offset would point to count bytes before the last non-padded byte. avr-prop-8.s reproduces this scenario. To fix scenario 1, the patch adds an additional check to ensure reloc addends aren't adjusted if they cross a shrink boundary. The shrink boundary is either the section size or an alignment boundary. Addends pointing at an alignment boundary don't need to be adjusted, as padding would occur and keep the boundary the same. Addends pointing at section size need to be adjusted though, as no padding occurs and the section size itself would get decremented. The patch records whether padding occured (did_pad) and uses that to detect and handle this condition. To fix scenario 2, the patch adds an additional parameter (delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish instruction bytes deletion from padding bytes deletion. It then uses that to correctly set shrinked_insn_address. bfd/ChangeLog: 2016-09-02 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/20545 * elf32-avr.c (elf32_avr_relax_delete_bytes): Add parameter delete_shrinks_insn.
