Richard Smith	6b53e224eb	Split -fsanitize=bounds to -fsanitize=array-bounds (for the frontend-inserted check using the ubsan runtime) and -fsanitize=local-bounds (for the middle-end check which inserts traps). Remove -fsanitize=local-bounds from -fsanitize=undefined. It does not produce useful diagnostics and has false positives (PR17635), and is not a good compromise position between UBSan's checks and ASan's checks. Map -fbounds-checking to -fsanitize=local-bounds to restore Clang's historical behavior for that flag. llvm-svn: 193205	2013-10-22 22:51:04 +00:00

Split -fsanitize=bounds to -fsanitize=array-bounds (for the frontend-inserted

check using the ubsan runtime) and -fsanitize=local-bounds (for the middle-end
check which inserts traps).

Remove -fsanitize=local-bounds from -fsanitize=undefined. It does not produce
useful diagnostics and has false positives (PR17635), and is not a good
compromise position between UBSan's checks and ASan's checks.

Map -fbounds-checking to -fsanitize=local-bounds to restore Clang's historical
behavior for that flag.

add -fbounds-checking option.

When enabled, clang generates bounds checks for array and pointers dereferences. Work to follow in LLVM's backend.

OK'ed by Chad; thanks for the review.
