| | | | | | | | | | | | | | | | | CodeGen: Don't emit linkage on thunks that aren't emitted because they're vararg. This can happen when we're trying to emit a thunk with available_externally linkage with optimization enabled but bail because it doesn't make sense for vararg functions. [LLVM] PR18098. This should fix clang "Broken module found, compilation aborted" errors when building the qt4-based dvbcut port. Reported by: se MFC after: 3 days

| | | | | | | | | | | | | Move the body of GCCInstallationDetector ctor into an init() function and call it from its only user. The linux toolchain. This saves quite a lot of directory searching on other platforms. See http://docs.freebsd.org/cgi/mid.cgi?51E6FAF5.3080802 for the original discussion. With this fix, the search for gcc installations is completely eliminated on FreeBSD. Reported by: Kurt Lidl <lidl@pix.net> MFC after: 3 days

* On platforms where clang is the default compiler, don't build gcc or libstdc++.theraven2013-09-062-0/+37
| | | | | | | | | | | | | | | | | | To enable them, set WITH_GCC and WITH_GNUCXX in src.conf. Make clang default to using libc++ on FreeBSD 10. Bumped __FreeBSD_version for the change. GCC is still enabled on PC98, because the PC98 bootloader requires GCC to build (or, at least, hard-codes the use of gcc into its build). Thanks to everyone who helped make the ports tree ready for this (and bapt for coordinating them all). Also to imp for reviewing this and working on the forward-porting of the changes in our gcc so that we're getting to a much better place with regard to external toolchains. Sorry to all of the people who helped who I forgot to mention by name. Reviewed by: bapt, imp, dim, ...
* Pull in r182983 from upstream clang trunk:dim2013-08-201-5/+10
| | | | | | | | | | | | | | | | | Fix handling of braced-init-list as reference initializer within aggregate initialization. Previously we would incorrectly require an extra set of braces around such initializers. Pull in r188718 from upstream clang trunk: Handle init lists and _Atomic fields. Fixes PR16931. These fixes are needed for the atomic_flag type to work correctly in our stdatomic.h. Requested by: theraven

* Pull in r186696 from upstream clang trunk:dim2013-07-301-2/+124
| | | | | | | | | | | | | | | | | This patch implements __get_cpuid_max() as an inline and __cpuid() and __cpuid_count() as macros to be compatible with GCC's cpuid.h. It also adds bit_<foo> constants for the various feature bits as described in version 039 (May 2011) of Intel's SDM Volume 2 in the description of the CPUID instruction. The list of bit_<foo> constants is a bit exhaustive (GCC doesn't do near this many). More bits could be added from a newer version of SDM if desired. Patch by John Baldwin! This should fix several ports which depend on this functionality being available. MFC after: 1 week

* Pull in r183926 from LLVM trunk:andrew2013-06-151-1/+2
| | | | | | | | | | | Allow clang to build __clear_cache on ARM. __clear_cache is special. It needs no signature, but is a real function in compiler_rt or libgcc. Patch by Andrew Turner. This allows us to build the __clear_cache function in compiler-rt.
* Pull in r184040 from upstream clang trunk:ed2013-06-151-2/+2
| | | | | | | | | | | | Emit native implementations of atomic operations on FreeBSD/armv6. Just like on Linux, FreeBSD/armv6 assumes the system supports ldrex/strex unconditionally. It is also used by the kernel. We can therefore enable support for it, like we do on Linux. While there, change one of the unit tests to explicitly test against armv5 instead of armv7, as it actually tests whether libcalls are emitted.

* Pull in r183033 and r183036 from LLVM trunk:ed2013-06-011-28/+105
| | | | | | | | | | | | | | | | | | | | | | Add support for optimized (non-generic) atomic libcalls. For integer types of sizes 1, 2, 4 and 8, libcompiler-rt (and libgcc) provide atomic functions that pass parameters by value and return results directly. libgcc and libcompiler-rt only provide optimized libcalls for __atomic_fetch_*, as generic libcalls on non-integer types would make little sense. This means that we can finally make __atomic_fetch_* work on architectures for which we don't provide these operations as builtins (e.g. ARM). This should fix the dreaded "cannot compile this atomic library call yet" error that would pop up once every while. This should make it possible for me to get C11 atomics working on all of our platforms.

* Pull in r177252 from upstream clang trunk:andrew2013-03-201-0/+1

* Pull in r172354 from upstream clang trunk:dim2013-02-222-61/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the x86 CPU name logic in the driver and pass -march and -mcpu flag information down from the Clang driver into the Gold linker plugin for LTO. This allows specifying -march on the linker commandline and should hopefully have it pass all the way through to the LTO optimizer. Fixes PR14697. Pull in r175919 from upstream clang trunk: Driver: Pass down the -march setting down to -cc1as on x86 too. The assembler historically didn't make use of any target features, but this has changed when support for old CPUs that don't support long nops was added. This should fix the long nops that still occurred in crt*.o, and possibly other object files, if the system was compiled for a CPU that does not support those, such as Geode. Note that gcc on i386 also does not pass through any -march, -mcpu or -mtune setting to gas, but this has not caused any trouble yet, because gas defaults to i386. Reported by: lev MFC after: 1 week
* Pull in r170135 from upstream clang trunk:dim2013-02-021-2/+44
| | | | | | | | | | | | | | | | Dont use/link ARCMT, StaticAnalyzer and Rewriter to clang when the user specifies not to. Dont build ASTMatchers with Rewriter disabled and StaticAnalyzer when it's disabled. Without all those three, the clang binary shrinks (x86_64) from ~36MB to ~32MB (unstripped). To disable these clang components, and get a smaller clang binary built and installed, set WITHOUT_CLANG_FULL in src.conf(5). During the initial stages of buildworld, those extra components are already disabled automatically, to save some build time. MFC after: 1 week

Fixes an issue reported as comment#3 in PR12763 -- we sometimes assert in codegen if we try to emit a reference to a function declaration which we've not marked as referenced.
