Evgeniy Stepanov	f02b782aa7	[cfi] Fix handling of uninstrumented libraries. ... CFI shadow for non-CFI libraries should be "unchecked", not "invalid". llvm-svn: 256285	2015-12-22 21:40:09 +00:00
Evgeniy Stepanov	72b0111ce6	[cfi] Exclude ubsan runtime library from non-diag CFI builds. ... Split the CFI runtime in two: cfi and cfi_diag. The latter includes UBSan runtime to allow printing diagnostics. llvm-svn: 255735	2015-12-16 00:38:41 +00:00
Evgeniy Stepanov	702a773988	[cfi] Fix GCC build. ... llvm-svn: 255733	2015-12-16 00:34:30 +00:00
Evgeniy Stepanov	b99d6c8b2a	[cfi] Fix shadow sanity check. ... The current check may break if the starting address in fill_shadow is not page-aligned. llvm-svn: 255725	2015-12-16 00:18:04 +00:00
Evgeniy Stepanov	da1cf9287c	Cross-DSO control flow integrity (compiler-rt part). ... This is an initial version of the runtime cross-DSO CFI support library. It contains a number of FIXMEs, ex. it does not support the diagnostic mode nor dlopen/dlclose, but it works and can be tested. Diagnostic mode, in particular, would require some refactoring (we'd like to gather all CFI hooks in the UBSan library into one function so that we could easier pass the diagnostic information down to __cfi_check). It will be implemented later. Once the diagnostic mode is in, I plan to create a second test configuration to run all existing tests in both modes. For now, this patch includes only a few new cross-DSO tests. llvm-svn: 255695	2015-12-15 23:00:33 +00:00
