2012-11-29This patch exposes to Clang users three more sanitizers are experimental ↵Alexey Samsonov1-0/+7
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. llvm-svn: 168950

2012-11-23Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.Bob Wilson1-612/+10
Unlike my previous attempt at this, this patch leaves intact the check for whether clang can handle the input file type, and for non-Darwin toolchains it will invoke gcc for things it cannot handle. For Darwin toolchains, the behavior reported in pr14338 still occurs with this patch, but that is a definite improvement from what happens currently, where it just crashes with an assertion failure. llvm-svn: 168505
2012-11-21Fix the '-fuse-init-array' option to actually be an option.Chandler Carruth1-1/+1
Previously, this flag to CC1 was never exposed at the clang driver layer, and if you happened to enable it (by being on Android or GCC 4.7 platform), you couldn't *disable* it, because there was no 'no' variant. The whole thing was confusingly implemented. Now, the target-specific flag processing gets the driver arg list, and we use standard hasFlag with a default based on the GCC version and/or Android platform. The user can still pass the 'no-' variant to forcibly disable the flag, or pass the positive variant to clang itself to enable the flag. The test has also been substantially cleaned up and extended to cover these use cases. llvm-svn: 168473
2012-11-19Add -ldl for non-static libgcc in Android.Logan Chien1-3/+11
According to Android ABI, we have to link with libdl.so, if we are linking with non-static libgcc. Besides, this also fixes MIPS link error of undefined references to `_Unwind_Find_FDE' and `dl_iterate_phdr'. llvm-svn: 168310
2012-11-19Completely re-work how the Clang driver interprets PIC and PIE options.Chandler Carruth1-67/+74
There were numerous issues here that were all entangled, and so I've tried to do a general simplification of the logic. 1) The logic was mimicing actual GCC bugs, rather than "features". These have been fixed in trunk GCC, and this fixes Clang as well. Notably, the logic was always intended to be last-match-wins like any other flag. 2) The logic for handling '-mdynamic-no-pic' was preposterously unclear. It also allowed the use of this flag on non-Darwin platforms where it has no actual meaning. Now this option is handled directly based on tests of how llvm-gcc behaves, and it is only supported on Darwin. 3) The APIs for the Driver's ToolChains had the implementation ugliness of dynamic-no-pic leaking through them. They also had the implementation details of the LLVM relocation model flag names leaking through. 4) The actual results of passing these flags was incorrect on Darwin in many cases. For example, Darwin *always* uses PIC level 2 if it uses in PIC level, and Darwin *always* uses PIC on 64-bit regardless of the flags specified, including -fPIE. Darwin never compiles in PIE mode, but it can *link* in PIE mode. 5) Also, PIC was not always being enabled even when PIE was. This isn't a supported mode at all and may have caused some fallout in builds with complex PIC and PIE interactions. The result is (I hope) cleaner and clearer for readers. I've also left comments and tests about some of the truly strage behavior that is observed on Darwin platforms. We have no real testing of Windows platforms and PIC, but I don't have the tools handy to figure that out. Hopefully others can beef up our testing here. Unfortunately, I can't test this for every platform. =/ If folks have dependencies on these flags that aren't covered by tests, they may break. I've audited and ensured that all the changes in behavior of the existing tests are intentional and good. In particular I've tried to make sure the Darwin behavior (which is more suprising than the Linux behavior) also matches that of 'gcc' on my mac. llvm-svn: 168297

2012-11-13This patch makes the behavior of clang consistent with the behavior of gcc ↵Benjamin Kramer1-7/+19
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.

2012-11-06Per discussion on cfe-commits, treat -faddress-sanitizer,Richard Smith1-13/+27
-fno-address-sanitizer, -fthread-sanitizer, -fno-thread-sanitizer, and -fcatch-undefined-behavior as deprecated: produce a warning if they are used pointing to the corresponding -fsanitize= option. In passing add the missing '-' to some diagnostics. llvm-svn: 167429
2012-11-05Use the individual -fsanitize=<...> arguments to control which of the UBSanRichard Smith1-6/+0
checks to enable. Remove frontend support for -fcatch-undefined-behavior, -faddress-sanitizer and -fthread-sanitizer now that they don't do anything. llvm-svn: 167413
2012-11-05Add -fsanitize=<sanitizers> argument to driver and frontend, and addRichard Smith1-21/+162
-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. llvm-svn: 167411

2012-10-22[Options] Add prefixes to options.Michael J. Spencer1-3/+3
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. llvm-svn: 166444
