Richard Smith	7e45562ad0	ubsan: Demangle class names, and be more informative when a reinterpret_cast ... has got us to the wrong offset within an object. llvm-svn: 170423	2012-12-18 09:30:21 +00:00
Richard Smith	cf56ebd52a	ubsan: When diagnosing something wrong somewhere in memory, emit a note ... pointing at the bad location and a snippet of nearby memory values. This is strictly best-effort; reading these bytes to display the note could lead to a seg fault, and that's explicitly OK. llvm-svn: 170415	2012-12-18 06:30:32 +00:00
Richard Smith	52987120f9	ubsan: if the frontend didn't provide us with a source location, try to work ... one out from the return address. Currently, we can only resolve this address to a file and line number if we have an external symbolizer. llvm-svn: 170407	2012-12-18 04:23:18 +00:00
Will Dietz	b28179be10	[ubsan] Replace "fatal error" with "runtime error". ... llvm-svn: 169112	2012-12-02 18:43:33 +00:00
Richard Smith	05dce7e644	-fsanitize=undefined: Switch to using sanitizer_common for output. This gets us much closer to not depending on any system headers. ... llvm-svn: 167888	2012-11-13 23:42:05 +00:00
Chandler Carruth	eea8a48218	Fix the bootstrap of CompilerRT with host compilers that don't support ... emulating 128-bit arithmetic on 32-bit x86 targets. This should get the bootstrap back for GCC 4.6 at least. Suggestions on better ways to do the detection here are welcome... llvm-svn: 165863	2012-10-13 02:30:10 +00:00
Richard Smith	7247b23efc	-fcatch-undefined-behavior: Runtime library support for trapping conversions to or ... from a floating-point type where the source value is not in the range of representable values of the destination type. llvm-svn: 165844	2012-10-12 22:57:15 +00:00
Richard Smith	68b3014cd3	Add a runtime diagnostics library for Clang's -fcatch-undefined-behavior. ... llvm-svn: 165533	2012-10-09 19:34:32 +00:00
