10203 exist. Reorder table to group similar options. Add missing
10204 @opindex entries. Add @need commands throughout the table to
10205 allow it to be split across multiple pages.
10206 ([-m8bit-idiv]): Fix @opindex.
10207 ([-mavx256-split-unaligned-load]): Likewise.
10208 ([-mavx256-split-unaligned-store]): Likewise.
10209 ([-mstack-protector-guard]): Likewise.
10210 ([-mcpu=]): Likewise.
10211 ([-mcpu]): Likewise.
10212 ([-mpointer-size=]): Likewise.

10216 * config/pa/pa.md (decrement_and_branch_until_zero): Use `Q' constraint
10217 instead of `m' constraint. Likewise for unnamed movb comparison
10218 patterns using reg_before_reload_operand predicate.
10219 * config/pa/predicates.md (reg_before_reload_operand): Tighten
10220 predicate to reject register index and LO_SUM DLT memory forms
10221 after reload.

10226 -fdevirtualize-at-ltrans.
10227 ([-fdevirtualize]): Fix markup.
10228 ([-fdevirtualize-speculatively]): Fix typo.
10229 ([-fdevirtualize-at-ltrans]): Likewise. Make description less
10230 implementor-speaky.
10231 * common.opt (fdevirtualize-at-ltrans): Likewise.
10232 * ipa-devirt.c: Fix typos in comments throughout the file.
10233 (ipa_devirt): Fix typos in format strings for dump output.

10237 * doc/invoke.texi ([-fopt-info]): Fix markup, consolidate
10238 discussion of defaults, light copy-editing.

10242 * tsan.c (instrument_expr): corrected previous checkin.
10244 2015-01-02 Bernd Edlinger <bernd.edlinger@hotmail.de>
10246 Instrument bit field and unaligned accesses for TSAN.
10247 * sanitizer.def (BUILT_IN_TSAN_READ_RANGE): New built-in function.
10248 (BUILT_IN_TSAN_WRITE_RANGE): New built-in function.
10249 * tsan.c (instrument_expr): Handle COMPONENT_REF and BIT_FIELD_REF.
10250 Use BUILT_IN_TSAN_READ_RANGE and BUILT_IN_TSAN_WRITE_RANGE for
10251 unaligned memory regions.
