* sanitizer: new "strict_string_checks" run-time flagDmitry Vyukov2015-04-0615-90/+643
| | | | | | | | | | This patch is related to Issue 346: moar string interceptors: strstr, strcasestr, strcspn, strpbrk As was suggested in original review http://reviews.llvm.org/D6056 a new "strict_string_checks" run-time flag introduced. The flag support applied for existing common, asan, msan and tsan interceptors. New asan tests added. Change by Maria Guseva reviewed in http://reviews.llvm.org/D7123 llvm-svn: 234187

* Add hard float versions of FP to LL conversionsSergey Dmitrouk2015-04-064-4/+97
| | | | | | | | | | | | | | | | | | | | | | | | | This adds hard-float implementation for the following builtins: * __fixdfdi() * __fixsfdi() * __fixunsdfdi() * __fixunssfdi() The soft-float implementation does never raise floating point exceptions, which doesn't allow clients to detect floating point conversion errors. I must mention that I had to refer to libgcc's implementation to write these functions. Related unit-tests of compiler-rt passed with these changes. Patch was somewhat out-dated, so was updated locally without any functional changes. Differential Revision: http://reviews.llvm.org/D5376 llvm-svn: 234148

| | | | | | | | | MetaMap::ResetRange/FreeRange rounds the range up to at least kMetaShadowSize. This is requried for e.g. free(malloc(0)). However, munmap returns EINVAL and do not unmap any memory when length arguments is equal to 0. So don't free meta shadow in this case as well. llvm-svn: 234145

* profile: Protect .gcda output with flockJustin Bogner2015-04-031-0/+6
| | | | | | | | | | | This avoids crashing or corrupting data if multiple concurrent processes write to the same .gcda file. This is hard to test, since the previous behaviour was a data race that often worked out, and it ignores errors in flock to fall back to the old racy behaviour so that it won't degrade the behaviour on filesystems that don't support flock. llvm-svn: 234036

* [UBSan] Embed UBSan into ASan runtime (compiler-rt part).Alexey Samsonov2015-04-0119-117/+203
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Change the way we use ASan and UBSan together. Instead of keeping two separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on a platform, all UBSan sources are just compiled into dummy empty object files. UBSan initialization code (e.g. flag parsing) is directly called from ASan initialization, so we are able to enforce correct initialization order. This mirrors the approach we already use for ASan+LSan. This change doesn't modify the way we use standalone UBSan.

We expect the flags to be the same on Linux and FreeBSD. If there's another reason for the tests to fail on FreeBSD, they'll need to be disabled. llvm-svn: 233822
