2012-04-01Ignore unused --serialize-diagnostics option when using llvm-gcc.Bob Wilson
llvm-gcc doesn't handle --serialize-diagnostics so when compiling i386 kernel/kext code with -Werror, you get an error about that option being unused. Claim the argument to prevent this from breaking builds. <rdar://problem/11161933> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153854 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-29ARM backend knows about cortex-m4. The front end should too.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153678 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-27Move the emission of strict enum range metadata behind a flag (the sameChandler Carruth
flag as GCC uses: -fstrict-enums). There is a *lot* of code making unwarranted assumptions about the underlying type of enums, and it doesn't seem entirely reasonable to eagerly break all of it. Much more importantly, the current state of affairs is *very* good at optimizing based upon this information, which causes failures that are very distant from the actual enum. Before we push for enabling this by default, I think we need to implement -fcatch-undefined-behavior support for instrumenting and trapping whenever we store or load a value outside of the range. That way we can track down the misbehaving code very quickly. I discussed this with Rafael, and currently the only important cases he is aware of are the bool range-based optimizations which are staying hard enabled. We've not seen any issue with those either, and they are much more important for performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153550 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-26[driver] Fix unused argument warnings.Chad Rosier
1. Don't short-circuit conditional statements that are checking flags. Otherwise, the driver emits warnings about unused arguments. 2. -mkernel and -fapple-kext imply no exceptions, so claim exception related arguments now to avoid warnings about unused arguments. rdar://11120518 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153478 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21Duplicated code is bad. At least make it consistent.Bob Wilson
The getARMTargetCPU and getLLVMArchSuffixForARM functions exist in both Toolchain.cpp and Tools.cpp. This stuff needs a thorough overhaul. In the meantime, this patch at least makes them consistent. One version had been converted to use StringSwitch, and the other version had new Cortex M-series processors added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153202 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-15Reapply r152745 (reverted in 152765) now that compiler-rt is fixed.David Blaikie
Original commit message: Provide -Wnull-conversion separately from -Wconversion. Like GCC, provide a NULL conversion to non-pointer conversion as a separate flag, on by default. GCC's flag is "conversion-null" which we provide for cross compatibility, but in the interests of consistency (with -Wint-conversion, -Wbool-conversion, etc) the canonical Clang flag is called -Wnull-conversion. Patch by Lubos Lunak. Review feedback by myself, Chandler Carruth, and Chad Rosier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152774 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-06Add new code migrator support for migrating existing Objective-C code to useTed Kremenek
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax. This introduces a new library, libEdit, which provides a new way to support migration of code that improves on the original ARC migrator. We now believe that most of its functionality can be refactored into the existing libraries, and thus this new library may shortly disappear. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152141 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 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

2012-02-15Remove the unuseful -fdiagnostics-show-nameDavid Blaikie
This option was added in r129614 and doesn't have any use case that I'm aware of. It's possible that external tools are using these names - and if that's the case we can certainly reassess the functionality, but for now it lets us shave out a few unneeded bits from clang. Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool. This removes the actual diagnostic name strings from clang entirely.
