* [CUDA] Invoke ptxas and fatbinary during compilation.Justin Lebar2016-01-141-0/+78
| | | | | | | | | | | | | | | | | | | | Summary: Previously we compiled CUDA device code to PTX assembly and embedded that asm as text in our host binary. Now we compile to PTX assembly and then invoke ptxas to assemble the PTX into a cubin file. We gather the ptx and cubin files for each of our --cuda-gpu-archs and combine them using fatbinary, and then embed that into the host binary. Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary, which pass args down to the external tools.

| | | | | | | | | | | | | | | | | Summary: In rL256641, @davide turned off movt generation by default for FreeBSD. This was because our ld is very old, and did not support the relocations for it. However, Ian Lepore added the support very recently, so we would like to revert rL256641, and replace it with a new `-fno-movt` frontend option. This way, it can be turned off when needed.

* Fix C++ support on recent DragonFly BSD releasesDimitry Andric2015-12-271-28/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: [ Copied from https://llvm.org/bugs/show_bug.cgi?id=25597 ] Clang support for DragonFly BSD is lagging a bit, resulting in poor support for c++. DragonFlyBSD is unique in that it has two base compilers. At the time of the last Clang update for DragonFly, these compilers were GCC 4.4 and GCC 4.7 (default). With DragonFly Release 4.2, GCC 4.4 was replaced with GCC 5.0, partially because the C++11 support of GCC 4.7 was incomplete. The DragonFly project will Release version 4.4 soon. This patch updates the Clang driver to use libstdc++ from GCC 5.2 The support for falling back to the alternate compiler was removed for two reasons: 1) The last release to use GCC 4.7 is DF 4.0 which has already reached EOL 2) GCC 4.7 libstdc++ is insufficient for many "ports" Therefore, I think it is reasonable that the development version of clang expects GCC 5.2 to be in place and not try to fall back to another compiler. The attached patch will do this. The Tools.cpp file was signficantly modified to fix the linking which had been changed somewhere along the line. The rest of the changes should be self-explanatory.

* [WebAssembly] Remove the -target command-line flag from the ld commandline.Dan Gohman2015-12-211-2/+0

* [clang-cl] Add support for /BreproDavid Majnemer2015-12-211-0/+9
| | | | | | | | | | | | The /Brepro flag controls whether or not the compiler should embed timestamps into the object file. Object files which do not embed timestamps are not suitable for incremental linking but are suitable for hermetic build systems and staged self-hosts of clang. A normal clang spelling of this flag has been added, -mincremental-linker-compatible. llvm-svn: 256204

* Driver part of debugger tuning.Paul Robinson2015-12-191-24/+64
| | | | | | | | | | | | | | | | Adds driver options named -glldb and -gsce to mean -g plus tuning for lldb and SCE debuggers respectively; the existing -ggdb option does the same for gdb. Existing options -ggdb0, -ggdb1 etc. unpack into -ggdb -g<N>. (There will not be -glldb<N> or -gsce<N> options.) The tuning gets a target-specific default in the driver, and is passed into cc1 with the new -debugger-tuning option. As fallout, fixes where '-gsplit-dwarf -g0' would ignore the -g0 part on Linux.

* PIC should not be enabled by default on Darwin with -static.Bob Wilson2015-12-181-0/+3
| | | | | | | | | | | r245667 changed -static so that it doesn't override an explicit -fPIC option, but -static should still change the default for Darwin for -fno-PIC.

* [ThinLTO] Option to invoke ThinLTO backend passes and importingTeresa Johnson2015-12-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Adds new option -fthinlto-index=<file> to invoke the LTO pipeline along with function importing via clang using the supplied function summary index file. This supports invoking the parallel ThinLTO backend processes in a distributed build environment via clang. Additionally, this causes the module linker to be invoked on the bitcode file being compiled to perform any necessary promotion and renaming of locals that are exported via the function summary index file. Add a couple tests that confirm we get expected errors when we try to use the new option on a file that isn't bitcode, or specify an invalid index file. The tests also confirm that we trigger the expected function import pass.
