2012-11-15Make -ffp-contract a codegen option, rather than a laguage option. This makesLang Hames
more sense anyway - it determines how expressions are codegen'd. It also ensures that -ffp-contract=fast has the intended effect when compiling LLVM IR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168027 91177308-0d34-0410-b5e6-96231b3b80d8

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

2012-10-19IRgen: Initialize TargetLoweringInfo with a triple.Daniel Dunbar
- We create two TargetLoweringInfo instances for different pass managers, and they weren't consistent (the one for codegen didn't have the right info).

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

2012-02-03Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325>Bob Wilson
That llvm change removed the -trap-func backend option, so that using -ftrap-function with clang would cause the backend to complain.
