2012-11-13This patch makes the behavior of clang consistent with the behavior of gcc ↵Benjamin Kramer
4.6 in cases where both -fPIC and -fPIE is used. - Separately check if -fPIE was specified in the command line and define both __PIC__ and __PIE__ when -fPIE is used. We need to check this separately because -fPIE will infer -fPIC even if its not explicitly used. - Fixed existing tests. - Added new tests for cases where both -fPIC and -fPIE is used.

2012-11-05Add -fsanitize=<sanitizers> argument to driver and frontend, and addRichard Smith
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the various UBSan checks to be enabled and disabled separately. Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167411 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-22[Options] Add prefixes to options.Michael J. Spencer
Each option has a set of prefixes. When matching an argument such as -funroll-loops. First the leading - is removed as it is a prefix. Then a lower_bound search for "funroll-loops" is done against the option table by option name. From there each option prefix + option name combination is tested against the argument. This allows us to support Microsoft style options where both / and - are valid prefixes. It also simplifies the cases we already have where options come in both - and -- forms. Almost every option for gnu-ld happens to have this form. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166444 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-04Driver: Link crtfastmath.o if it's available and -ffast-math is specified.Benjamin Kramer
crtfastmath.o contains routines to set the floating point flags to a faster, unsafe mode. Linking it in speeds up code dealing with denormals significantly (PR14024). For now this is only enabled on linux where I can test it and crtfastmath.o is widely available. We may want to provide a similar file with compiler-rt eventually and/or enable it on other platforms too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165240 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-02During LTO, we call 'dsymutil' when we compile source files. This necessitatesBill Wendling
clang specifying a temporary file that it later cleans up so that it can survive the linking stage. However, when we compile object files during LTO we don't call 'dsymutil'. That's done at a different stage (if at all). We rely upon the linker to specify a unique name for the temporary file it generates. <rdar://problem/12401423> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165028 91177308-0d34-0410-b5e6-96231b3b80d8
