* Forward -u to the linker on gnutools toolchainsReid Kleckner2014-06-261-0/+1
| | | | | | | | | | | | | | | | Summary: The BSDs and Darwin all forward the whole 'u' group, but gcc only forwards -u so far as I can tell. I only forward -u, since that's a minimal change, and many people object to magically recognizing and forwarding linker arguments.

* [mips] Correct linux dynamic linker for -mnan=2008Daniel Sanders2014-06-241-5/+24
| | | | | | | | | | | | Summary: The dynamic linker is named ld-linux-mipsn8.so.1 when -mnan=2008 is given (or is the default). It remains ld.so.1 for other cases. This is necessary for MIPS32r6/MIPS64r6 since these ISA's default to -mnan=2008. Differential Revision: http://reviews.llvm.org/D4273 llvm-svn: 211598
* Driver: In crashdumps with -fmodule, dump the module dependenciesJustin Bogner2014-06-201-17/+40
| | | | llvm-svn: 211421
* Driver: Record that we're in crashdump and push flags to ConstructJobJustin Bogner2014-06-201-4/+5
| | | | | | | | | | | It's more flexible and arguably better layering to set flags to modify compiling for diagnostics in the CC1 job themselves, rather than tweaking the driver flags and letting them propagate. There is one visible change this causes: crash report files will now get preprocessed names (.i and friends). llvm-svn: 211411
* Driver: Remove some superfluous calls to Arg->claim()Justin Bogner2014-06-201-14/+5
| | | | | | | Args.getLastArg() claims the Arg it returns, so calling claim on these results is unnecessary. llvm-svn: 211403
* [PowerPC] Fix ELF interpreter name for powerpc64le-linuxUlrich Weigand2014-06-201-1/+2
| | | | | | | | | | On PowerPC LE the system uses the /lib64/ld64.so.2 dynamic linker name instead of /lib64/ld64.so.1 (to indicate the ELFv2 ABI version). This fixes the clang driver to pass the appropriate -dynamic-linker setting, and adds some more tests to linux-ld.c. llvm-svn: 211360
* Driver: correct the backend option spellingSaleem Abdulrasool2014-06-181-1/+1
| | | | | | The backend option does not have an '-enable' prefix. llvm-svn: 211177
* Add support for the /EP argument to clang-clHans Wennborg2014-06-131-0/+6
| | | | | | | | | | This maps the /EP argument to both -E and -P. Patch by Ehsan Akhgari! Differential Reviion: http://reviews.llvm.org/D4133 llvm-svn: 210935
* Use dwarf-2 by default on OpenBSD and FreeBSD.Brad Smith2014-06-131-4/+8
| | | | | | | The Tools.cpp part of the patch partially based on a patch from FreeBSD's LLVM tree. llvm-svn: 210883
* Driver: use more range-based for loopsSaleem Abdulrasool2014-06-121-145/+67
| | | | | | | Mechanical change converting some of the simpler for loops into range-based for loops. NFC. llvm-svn: 210738
* clang-cl: accept the /C option with /P (PR19978)Hans Wennborg2014-06-111-3/+7
| | | | | | (It's also allowed with /EP, but we haven't implemented that option yet.) llvm-svn: 210695
* Driver: add -m{,no-}long-calls supportSaleem Abdulrasool2014-06-071-0/+11
| | | | | | | | | | | | | This mirrors the GCC option for the ARM backend. This option enables the backend option "-enable-arm-long-calls". The default behaviour is that this is disabled due to the slight overhead of the generated calls. If the target of jumps are greater than 64M range of offset-based jumps, then the target address must be loaded into a register to make an indirect jump. The backend support for this has been present, but was not previously controllable by the proper flag. llvm-svn: 210398
* Implement -Wframe-larger-than backend diagnosticAlp Toker2014-06-051-0/+7
| | | | | | | | | | | | | | | | | | Add driver and frontend support for the GCC -Wframe-larger-than=bytes warning. This is the first GCC-compatible backend diagnostic built around LLVM's reporting feature. This commit adds infrastructure to perform reverse lookup from mangled names emitted after LLVM IR generation. We use that to resolve precise locations and originating AST functions, lambdas or block declarations to produce seamless codegen-guided diagnostics. An associated change, StringMap now maintains unique mangled name strings instead of allocating copies. This is a net memory saving in C++ and a small hit for C where we no longer reuse IdentifierInfo storage, pending further optimisation. llvm-svn: 210293
* Fix driver warning about -pthread on Android.Evgeniy Stepanov2014-06-051-3/+3
| | | | | | -pthread is no-op on Android. Suppress the unused argument warning. llvm-svn: 210253
* [ubsan] Don't add a --dynamic-list for ubsan symbols when building a sharedRichard Smith2014-06-041-2/+8
| | | | | | | | | library. That results in the linker resolving all references to weak symbols in the DSO to the definition from within that DSO. Ironically, this rarely causes observable problems, except that it causes ubsan's own dynamic type check to spuriously fail (because we fail to properly merge type_info object names). llvm-svn: 210220
* Add flags -Rpass-missed and -Rpass-analysis.Diego Novillo2014-05-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | Summary: These two flags are in the same family as -Rpass, but are used in different situations. -Rpass-missed is used by optimizers to inform the user when they tried to apply an optimization but couldn't (or wouldn't). -Rpass-analysis is used by optimizers to report analysis results back to the user (e.g., why the transformation could not be applied). Depends on D3682. Reviewers: rsmith Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D3683 llvm-svn: 209839

* -pthread does not translate to -lpthread on Android.Evgeniy Stepanov2014-05-281-2/+3
| | | | | | | There is no libpthread.so, and pthread interface is implemented in libc.so. This mirrors gcc behavior. llvm-svn: 209731
* AArch64/ARM64: rename ARM64 components to AArch64Tim Northover2014-05-241-13/+21
| | | | | | This keeps Clang consistent with backend naming conventions. llvm-svn: 209579
* AArch64/ARM64: update Clang after AArch64 removal.Tim Northover2014-05-241-22/+0
| | | | | | | | | | | A few (mostly CodeGen) parts of Clang were tightly coupled to the AArch64 backend. Now that it's gone, they will not even compile. I've also deduplicated RUN lines in many of the AArch64 tests. This might improve "make check-all" time noticably: some of those NEON tests were monsters. llvm-svn: 209578
* Don't reduce the stack protector level given -fstack-protector.Rafael Espindola2014-05-221-3/+4
| | | | | | | | | Before -fstack-protector would always force a level of 1, even if the default was 2. Patch by Brad Smith. llvm-svn: 209479
* Unify the name of compiler-rt builtins library on Linux.Alexey Samsonov2014-05-221-3/+4
| | | | | | | | | | Call it "libclang_rt.builtins-<arch>.a" to be consistent with sanitizers/profile libraries naming. Modify Makefile and CMake build systems and Clang driver accordingly. Fixes PR19822. llvm-svn: 209474
* MachO: perform ARM ABI detection even for non-Darwin triples.Tim Northover2014-05-221-1/+1
| | | | | | | | When "-arch armv7m" is specified, we want "aapcs", for example. rdar://problem/16581138 llvm-svn: 209434

* Driver: force restricted IT blocks for Windows on ARMSaleem Abdulrasool2014-05-181-0/+5
| | | | | | | Windows on ARM expects ARMv8 (restricted IT) conditional instructions only. Force enable the restricted IT mode via the backend option when targeting WoA. llvm-svn: 209086

* InstrProf: Look for the PIC-version of the profile runtimeDuncan P. N. Exon Smith2014-05-161-1/+8
| | | | | | | | If `-shared` is specified, pull in a PIC-version of the profile runtime, which was added to compiler-rt in r208947. I'm hoping this will get the bots on my side. llvm-svn: 208948
* clang-cl: Fall back immediately if /GR and /fallback were both passedReid Kleckner2014-05-141-1/+9
| | | | | | | None of our tests use /fallback, so this lets us gradually add RTTI support without breaking projects using /fallback. llvm-svn: 208787
* Support -masm= flag for x86 targets.Nico Weber2014-05-131-0/+11
| | | | | | | `clang -S -o - file.c -masm=att` will write assembly to stdout in at&t syntax (the default), `-masm=intel` will instead output intel style asm. llvm-svn: 208683

* [ASan] Split static ASan runtime in two parts: asan and asan_cxx.Alexey Samsonov2014-05-121-6/+11
| | | | | | | | | | | asan_cxx containts replacements for new/delete operators, and should only be linked in C++ mode. We plan to start building this part with exception support to make new more standard-compliant. See https://code.google.com/p/address-sanitizer/issues/detail?id=295 for more details. llvm-svn: 208610

| | | | | | | | | | | | | | After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and always print assembly that uses cfi directives. In llvm, MC itself supports cfi since the end of 2010 (support started in r119972, is reported in the 2.9 release notes). In binutils the support has been around for much longer. It looks like support started to be added in May 2003. It is available in 2.15 (31-Aug-2011, 2.14 is from 12-Jun-2003). llvm-svn: 207602
