10420 predicate to reject register index and LO_SUM DLT memory forms
10423 2015-01-02 Sandra Loosemore <sandra@codesourcery.com>
10425 * doc/invoke.texi (Option Summary): Fix spelling of
10426 -fdevirtualize-at-ltrans.
10427 ([-fdevirtualize]): Fix markup.
10428 ([-fdevirtualize-speculatively]): Fix typo.
10429 ([-fdevirtualize-at-ltrans]): Likewise. Make description less
10430 implementor-speaky.
10431 * common.opt (fdevirtualize-at-ltrans): Likewise.
10432 * ipa-devirt.c: Fix typos in comments throughout the file.
10433 (ipa_devirt): Fix typos in format strings for dump output.

10437 * doc/invoke.texi ([-fopt-info]): Fix markup, consolidate
10438 discussion of defaults, light copy-editing.

10442 * tsan.c (instrument_expr): corrected previous checkin.
10444 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
10446 Instrument bit field and unaligned accesses for TSAN.
10447 * sanitizer.def (BUILT_IN_TSAN_READ_RANGE): New built-in function.
10448 (BUILT_IN_TSAN_WRITE_RANGE): New built-in function.
10449 * tsan.c (instrument_expr): Handle COMPONENT_REF and BIT_FIELD_REF.
10450 Use BUILT_IN_TSAN_READ_RANGE and BUILT_IN_TSAN_WRITE_RANGE for
10451 unaligned memory regions.
10453 2015-01-01 Anthony Green <green@moxielogic.com>
10455 * config/moxie/predicates.md (moxie_general_movsrc_operand):
