The previous commit contained a small mistake in the ChangeLog, fixed in this commit.
2016-09-20ld: Extend documentation for EXCLUDE_FILEAndrew Burgess2-0/+20
There was a gap in the documentation of EXCLUDE_FILE that could cause confusion to a user. When writing an input section specifier like this: *(EXCLUDE_FILE (somefile.o) .text .text.*) this could mean one of the following: 1. All '.text' and '.text.*' from all files except for 'somefile.o', or 2. All '.text' from all files except 'somefile.o', and all '.text.*' sections from all files. It turns out that the second interpretation is correct, but the manual does not make this clear (to me at least). Hopefully this patch makes things clearer. ld/ChangeLog: * ld/ld.texinfo (Input Section Basics): Expand the description of EXCLUDE_FILE.

2016-09-06Fix PR ld/20545 - relaxation bugs in avr backendSenthil Kumar Selvaraj5-0/+51
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.

2016-08-29i386: Issue an error on non-PIC call to IFUNC in PIC objectH.J. Lu13-44/+79
On i386, IFUNC function must be called via PLT. Since PLT in PIC object uses EBX register, R_386_PLT32 relocation must be used to call IFUNC function even when IFUNC function is defined locally.

2016-08-25powerpc ld configureAlan Modra2-32/+74
This fixes a few problems in the powerpc ld configury. 1) Using powerpc*le-* to test for powerpcle and powerpc64le would incorrectly match a target triple like powerpc-apple-elf. 2) In the same vein, *64* could match 64 in the user supplied MANUF-OS part of the target triple. 3) tooldir vars were missing, and some target aliases would result in ridiculous values for those tdir_* vars given. 4) Since 2016-04-25, BE support was added automatically when asking for an LE target. If that is a good idea, then so is adding LE support when asking for BE. * configure.tgt (powerpc*-*-linux* et al): Rewrite, adding LE support for BE. First output all target endian configury values, then opposite endian. Handle more tooldirs. Fix bogus matches with strings in MANUF-OS part of target triple.

2016-07-27MIPS/GAS: Implement microMIPS branch/jump compactionMaciej W. Rozycki3-16/+17
Convert microMIPS branches and jumps whose delay slot would be filled by a generated NOP instruction to the corresponding compact form where one exists, in a manner similar to MIPS16 JR->JRC and JALR->JALRC swap. Do so even where the transformation switches from a 16-bit to a 32-bit branch encoding for no benefit in code size reduction, as this is still advantageous. This is because a branch/NOP pair takes 2 pipeline slots or a 2-cycle completion latency except in superscalar implementations. Whereas a compact branch may or may not stall on its target fetch, so it will at most have a 2-cycle completion latency and may have only 1 even in scalar implementations, and in superscalar implementations it is expected to have no worse latency as a branch/NOP pair has. Also it won't stall and therefore take the extra latency cycle in the not-taken case. Technically this is the same as MIPS16 compaction: for the qualifying instruction encodings the APPEND_ADD_COMPACT machine code generation method is selected where APPEND_ADD_WITH_NOP otherwise would and tells the code generator in `append_insn' to convert the regular form of an instruction to its corresponding compact form. For this the opcode is tweaked as necessary and the microMIPS opcode table is scanned for the matching updated instruction. A non-$0 `rt' operand to BEQ and BNE instructions is moved to the `rs' operand field of BEQZC and BNEZC encodings as required. Unlike with MIPS16 compaction however we need to handle out-of-distance branch relaxation as well. We do this by deferring the generation of any delay-slot NOP required to relaxation made in `md_convert_frag', by converting the APPEND_ADD_WITH_NOP machine code generation to APPEND_ADD where a relaxed instruction is recorded. Relaxation then, depending on actual code produced, chooses between either using a compact branch or jump encoding and emitting the NOP outstanding if no compact encoding is possible. For code simplicity's sake the relaxation pass is retained even if the principle of preferring a compact encoding to a 16-bit branch/NOP pair means, in the absence of out-of-range branch relaxation, that a single compact branch machine code instruction will eventually be produced from a given assembly source instruction. gas/ * config/tc-mips.c (RELAX_MICROMIPS_ENCODE): Add `nods' flag.
