binutils: fix .init/.fini literals moving in xtensa gas

2016-02-18T14:07:43+00:00

Despite the documentation and the comment in xtensa_move_literals, in the presence of --text-section-literals and --auto-litpools literals are moved from the separate literal sections into .init and .fini, because the check in the xtensa_move_literals is incorrect. This fixes build errors seen with projects that have .init/.fini and use text-section-literals.

binutils: backport auto-litpools xtensa gas option

2015-10-04T16:27:27+00:00

Auto-litpools is the automated version of text-section-literals: literal pool candidate frags are planted every N frags and during relaxation they are turned into actual literal pools where literals are moved to become reachable for their first reference by L32R instruction.

binutils: fix xtensa gas segfault with --text-section-literals

2015-07-11T10:33:13+00:00

Building libgcc with TARGET_ABI flags results in assembler segfault on xtensa, because code in sections .init and .fini emits literals w/o .literal_position directive. This patch turns the segfault into assembly error. Signed-off-by: Max Filippov Signed-off-by: Thomas Petazzoni

binutils: fix xtensa ld bug triggered by --gc-sections

2015-05-16T16:28:06+00:00

elf_xtensa_gc_sweep_hook doesn't correctly unreference symbols that were made local, that results in link failure with the following message: BFD (GNU Binutils) 2.24 internal error, aborting at elf32-xtensa.c line 3372 in elf_xtensa_finish_dynamic_sections elf_xtensa_gc_sweep_hook determines symbol reference type (PLT or GOT) by relocation type. Relocation types are not changed when symbol becomes local, but its PLT references are added to GOT references and plt.refcount is set to 0. Such symbol cannot be unreferences in the elf_xtensa_gc_sweep_hook and its extra references make calculated GOT relocations section size not match number of GOT relocations. Fix it by treating PLT reference as GOT reference when plt.refcount is not positive.

binutils: fix xtensa gas trampolines regression

2015-05-10T21:08:54+00:00

xtensa trampolines relaxation optimization caused the following build errors: Error: operand 1 of 'j' has out of range value '131643' Error: operand 1 of 'j' has out of range value '4294836162' Error: operand 1 of 'j' has out of range value '4294836072' Extra condition 'abs (addr - trampaddr) < J_RANGE / 2' for trampoline selection results in regressions: when relaxable jump is little longer than J_RANGE so that single trampoline makes two new jumps, one longer than J_RANGE / 2 and one shorter, correct trampoline cannot be found. Drop that condition. Upstream status: patch submitted. Fix squashed into the optimization patch.

binutils: backport xtensa trampolines relaxation optimization

binutils: backport xtensa ld optimizations

2015-04-09T19:52:36+00:00

This series optimizes most time-consuming algorithms and data structures in the xtensa link-time relaxation code, leaving relaxation logic intact. Speedup linking typical linux kernel is ~8 times (1 minute instead of 8), pathological cases (linking objects partially linked without relaxation) are handled ~60 times faster (1 minute instead of an hour).

binutils/2.24: add patch to warn about unsafe library paths

2014-12-10T23:05:52+00:00

This commit adds a patch to binutils borrowed from CodeSourcery/Yocto that warns about unsafe library paths (i.e /usr/lib, /usr/local/lib, etc.). The patch was adapted to binutils 2.24, and modified to support the BR_COMPILER_PARANOID_UNSAFE_PATH environment variable to error out instead of just warn when unsafe paths are used. Even though erroring out can be chosen by passing --error-poison-system-directories, we are not sure this option in LDFLAGS will always be passed, so having an environment variable guarantees it will always be passed, and also allows to have an identical behavior to the external toolchain wrapper.
