Peter Collingbourne	90a0876ae7	Runtime support for the indirect function call checker. Differential Revision: http://llvm-reviews.chandlerc.com/D1339 llvm-svn: 193060	2013-10-20 21:29:46 +00:00
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
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
