20484 @opindex entries. Add @need commands throughout the table to
20485 allow it to be split across multiple pages.
20486 ([-m8bit-idiv]): Fix @opindex.
20487 ([-mavx256-split-unaligned-load]): Likewise.
20488 ([-mavx256-split-unaligned-store]): Likewise.
20489 ([-mstack-protector-guard]): Likewise.
20490 ([-mcpu=]): Likewise.
20491 ([-mcpu]): Likewise.
20492 ([-mpointer-size=]): Likewise.

20496 * config/pa/pa.md (decrement_and_branch_until_zero): Use `Q' constraint
20497 instead of `m' constraint. Likewise for unnamed movb comparison
20498 patterns using reg_before_reload_operand predicate.
20499 * config/pa/predicates.md (reg_before_reload_operand): Tighten
20500 predicate to reject register index and LO_SUM DLT memory forms

20506 -fdevirtualize-at-ltrans.
20507 ([-fdevirtualize]): Fix markup.
20508 ([-fdevirtualize-speculatively]): Fix typo.
20509 ([-fdevirtualize-at-ltrans]): Likewise. Make description less
20510 implementor-speaky.
20511 * common.opt (fdevirtualize-at-ltrans): Likewise.
20512 * ipa-devirt.c: Fix typos in comments throughout the file.
20513 (ipa_devirt): Fix typos in format strings for dump output.
20515 2015-01-02 Sandra Loosemore <sandra@codesourcery.com>
20517 * doc/invoke.texi ([-fopt-info]): Fix markup, consolidate
20518 discussion of defaults, light copy-editing.
20520 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
20522 * tsan.c (instrument_expr): corrected previous checkin.
20524 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
20526 Instrument bit field and unaligned accesses for TSAN.
20527 * sanitizer.def (BUILT_IN_TSAN_READ_RANGE): New built-in function.
20528 (BUILT_IN_TSAN_WRITE_RANGE): New built-in function.
20529 * tsan.c (instrument_expr): Handle COMPONENT_REF and BIT_FIELD_REF.
20530 Use BUILT_IN_TSAN_READ_RANGE and BUILT_IN_TSAN_WRITE_RANGE for
20531 unaligned memory regions.
20533 2015-01-01 Anthony Green <green@moxielogic.com>
20535 * config/moxie/predicates.md (moxie_general_movsrc_operand):
20536 Restrict move source register offsets to 16 bits.
