* [PGO] cc1 option name change for profile instrumentationRong Xu2016-02-041-4/+6
| | | | | | | | | | | | This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level. Review: http://reviews.llvm.org/D16730 llvm-svn: 259811

* ARMv7k: select ABI based on v7k Arch rather than watchos OS.Tim Northover2016-01-271-1/+2
| | | | | | | | Various bits we'd like to use the new ABI actually compile with "-arch armv7k -miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how slices work. llvm-svn: 258976

* [Driver] Make sure -fno-math-builtin option is being passed by the driver.Chad Rosier2016-01-261-2/+3
| | | | | | | | | | Support for the -fno-math-builtin option was added in r186899. The codegen side is being tested in test/CodeGen/nomathbuiltin.c. The missing part was just passing the option through the driver. PR26317 llvm-svn: 258814

* [cfi] Cross-DSO CFI diagnostic mode (clang part)Evgeniy Stepanov2016-01-251-1/+4
| | | | | | | | | | | | | | * Runtime diagnostic data for cfi-icall changed to match the rest of cfi checks * Layout of all CFI diagnostic data changed to put Kind at the beginning. There is no ABI stability promise yet. * Call cfi_slowpath_diag instead of cfi_slowpath when needed. * Emit __cfi_check_fail function, which dispatches a CFI check faliure according to trap/recover settings of the current module. * A tiny driver change to match the way the new handlers are done in compiler-rt. llvm-svn: 258745

* [MSVC Compat] Only warn for unknown clang-cl argumentsEhsan Akhgari2016-01-251-0/+4
| | | | | | | | | | | | | | | | | Summary: MSVC's driver accepts all unknown arguments but warns about them. clang by default rejects all unknown arguments. This causes issues specifically with build systems such as autoconf which liberally pass things such as $LDFLAGS to the compiler and expect everything to work. This patch teaches clang-cl to ignore unknown driver arguments. Reviewers: rnk Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D16511 llvm-svn: 258720

* [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.

* [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.
