21384 @opindex entries. Add @need commands throughout the table to
21385 allow it to be split across multiple pages.
21386 ([-m8bit-idiv]): Fix @opindex.
21387 ([-mavx256-split-unaligned-load]): Likewise.
21388 ([-mavx256-split-unaligned-store]): Likewise.
21389 ([-mstack-protector-guard]): Likewise.
21390 ([-mcpu=]): Likewise.
21391 ([-mcpu]): Likewise.
21392 ([-mpointer-size=]): Likewise.

21396 * config/pa/pa.md (decrement_and_branch_until_zero): Use `Q' constraint
21397 instead of `m' constraint. Likewise for unnamed movb comparison
21398 patterns using reg_before_reload_operand predicate.
21399 * config/pa/predicates.md (reg_before_reload_operand): Tighten
21400 predicate to reject register index and LO_SUM DLT memory forms

21406 -fdevirtualize-at-ltrans.
21407 ([-fdevirtualize]): Fix markup.
21408 ([-fdevirtualize-speculatively]): Fix typo.
21409 ([-fdevirtualize-at-ltrans]): Likewise. Make description less
21410 implementor-speaky.
21411 * common.opt (fdevirtualize-at-ltrans): Likewise.
21412 * ipa-devirt.c: Fix typos in comments throughout the file.
21413 (ipa_devirt): Fix typos in format strings for dump output.
21415 2015-01-02 Sandra Loosemore <sandra@codesourcery.com>
21417 * doc/invoke.texi ([-fopt-info]): Fix markup, consolidate
21418 discussion of defaults, light copy-editing.
21420 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
21422 * tsan.c (instrument_expr): corrected previous checkin.
21424 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
21426 Instrument bit field and unaligned accesses for TSAN.
21427 * sanitizer.def (BUILT_IN_TSAN_READ_RANGE): New built-in function.
21428 (BUILT_IN_TSAN_WRITE_RANGE): New built-in function.
21429 * tsan.c (instrument_expr): Handle COMPONENT_REF and BIT_FIELD_REF.
21430 Use BUILT_IN_TSAN_READ_RANGE and BUILT_IN_TSAN_WRITE_RANGE for
21431 unaligned memory regions.
21433 2015-01-01 Anthony Green <green@moxielogic.com>
21435 * config/moxie/predicates.md (moxie_general_movsrc_operand):
21436 Restrict move source register offsets to 16 bits.
