2013-03-20The flag "-coverage-function-names-in-data" is actually backwards -- we doNick Lewycky
emit function names in .gcda files by default, and the flag turns that off! Rename the flag to make it match what it actually does. This keeps the default format compatible with gcc 4.2. Also add a test for this flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177475 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31[msan] Run more optimizations after MemorySanitizer pass.Evgeniy Stepanov
MSan instrumentation is driven by the original code. We take every incoming instruction and emit another instruction (or ten) next to it, operating on the shadow values (but sometimes on the real values, too). Two programs in one, essentially. There can be any kinds of redundancies in the second one, so we just run whatever is normally run at -O2, and then exclude some passes that do not help much with benchmarks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174049 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-29This patch exposes to Clang users three more sanitizers are experimental ↵Alexey Samsonov
features of ASan: 1) init-order sanitizer: initialization-order checker. Status: usable, but may produce false positives w/o proper blacklisting. 2) use-after-return sanitizer Status: implemented, but heavily understed. Should be optional, as it significanlty slows program down. 3) use-after-scope sanitizer Status: in progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168950 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-15Make -ffp-contract a codegen option, rather than a laguage option. This makesLang Hames

2012-10-24Clang now attempts to create a TargetMachine whenever a triple is given.Nadav Rotem
Many of our tests specify triples that are not built into clang. In this commit we allow clang to fail loading the triple if we are only using clang to emit llvm ir. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166543 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Add a -fuse-init-array option to cc1 and map to the UseInitArray targetRafael Espindola
option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-08Wire up -fpie and -fPIE to LLVM's newly added TargetOptions. No testChandler Carruth
case as we don't currently have any way of dumping target options or otherwise observing this. Another small step toward fixing PR12380. With this we generate TLS accesses using the static model instead of the dynamic model, but we're still generating suboptimal code under the mistaken assumption that the TLS offset might be greater than 2^32, and therefor not viable as an immediate offset of a segment register. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154298 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Add a flag -fthread-sanitizer.Kostya Serebryany
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151846 91177308-0d34-0410-b5e6-96231b3b80d8
