2016-03-04Switch krait to use -mcpu=cortex-a15 for assembler tool invocations.Stephen Hines1-2/+2
Summary: Using -no-integrated-as causes -mcpu=krait to be transformed into -march=armv7-a today. This precludes the assembler from using instructions like sdiv, which are present for krait. Cortex-a15 is the closest subset of functionality for krait, so we should switch the assembler to use that instead.

2016-03-02[PGO] Change profile use cc1 option to handle IR level profilesRong Xu1-2/+3
This patch changes cc1 option for PGO profile use from -fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>. -fprofile-instr-use=<path> is now a driver only option. In addition to decouple the cc1 option from the driver level option, this patch also enables IR level profile use. cc1 option handling now reads the profile header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM} -- this is a common enum for -fprofile-instrument={}, for the profile instrumentation), and invoke the pipeline to enable the respective PGO use pass.

2016-03-01clang-cl: Implement initial limited support for precompiled headers.Nico Weber1-1/+69
In the gcc precompiled header model, one explicitly runs clang with `-x c++-header` on a .h file to produce a gch file, and then includes the header with `-include foo.h` and if a .gch file exists for that header it gets used. This is documented at http://clang.llvm.org/docs/UsersManual.html#precompiled-headers cl.exe's model is fairly different, and controlled by the two flags /Yc and /Yu. A pch file is generated as a side effect of a regular compilation when /Ycheader.h is passed. While the compilation is running, the compiler keeps track of #include lines in the main translation unit and writes everything up to an `#include "header.h"` line into a pch file. Conversely, /Yuheader.h tells the compiler to skip all code in the main TU up to and including `#include "header.h"` and instead load header.pch. (It's also possible to use /Yc and /Yu without an argument, in that case a `#pragma hrdstop` takes the role of controlling the point where pch ends and real code begins.) This patch implements limited support for this in that it requires the pch header to be passed as a /FI force include flag – with this restriction, it can be implemented almost completely in the driver with fairly small amounts of code. For /Yu, this is trivial, and for /Yc a separate pch action is added that runs before the actual compilation. After r261774, the first failing command makes a compilation stop – this means if the pch fails to build the main compilation won't run, which is what we want. However, in /fallback builds we need to run the main compilation even if the pch build fails so that the main compilation's fallback can run. To achieve this, add a ForceSuccessCommand that pretends that the pch build always succeeded in /fallback builds (the main compilation will then fail to open the pch and run the fallback cl.exe invocation). If /Yc /Yu are used in a setup that clang-cl doesn't implement yet, clang-cl will now emit a "not implemented yet; flag ignored" warning that can be disabled using -Wno-clang-cl-pch. Since clang-cl doesn't yet serialize some important things (most notably `pragma comment(lib, ...)`, this feature is disabled by default and only enabled by an internal driver flag. Once it's more stable, this internal flag will disappear. (The default stdafx.h setup passes stdafx.h as explicit argument to /Yc but not as /FI – instead every single TU has to `#include <stdafx.h>` as first thing it does. Implementing support for this should be possible with the approach in this patch with minimal frontend changes by passing a --stop-at / --start-at flag from the driver to the frontend. This is left for a follow-up. I don't think we ever want to support `#pragma hdrstop`, and supporting it with this approach isn't easy: This approach relies on the driver knowing the pch filename in advance, and `#pragma hdrstop(out.pch)` can set the output filename, so the driver can't know about it in advance.) clang-cl now also honors /Fp and puts pch files in the same spot that cl.exe would put them, but the pch file format is of course incompatible. This has ramifications on /fallback, so /Yc /Yu aren't passed through to cl.exe in /fallback builds. http://reviews.llvm.org/D17695 llvm-svn: 262420
2016-03-01Introduce -fembed-bitcode driver optionSteven Wu1-0/+20
Summary: This is the clang driver part of the change to embedded bitcode. This includes: 1. -fembed-bitcode option which breaks down the compilation into two stages. The first stage emits optimized bitcode and the second stage compiles bitcode into object file. 2. -fembed-bitcode-marker option which doesn't really break down to two stages to speedup the compilation flow. 3. pass the correct linker flag to darwin linker if tool chains supports embedded bitcode.

option. Previously these options could both be used to specify that you were compiling the implementation file of a module, with a different set of minor bugs in each case. This change removes -fmodule-implementation-of, and instead tracks a flag to determine whether we're currently building a module. -fmodule-name now behaves the same way that -fmodule-implementation-of previously did. llvm-svn: 261372

2016-02-11[ARM] Add command-line options for ARMv8.2-AOliver Stannard1-4/+0
This allows ARMv8.2-A to be targeted either by using "armv8.2a" in the triple, or by using -march=armv8.2-a (or the alias -march=armv8.2a). The FP16 extension can be enabled with the "+fp16" suffix to the -march or -mcpu option. This is consistent with the AArch64 option, rather than the usual ARM option of -mfpu. We have agreed with the team which will be upstreaming this to GCC that we want to use this new option format for new architecture extensions for both ARM and AArch64. Most of the work for this was done by the TargetParser patch in llvm. Differential Revision: http://reviews.llvm.org/D15040 llvm-svn: 260533

2016-02-07Driver: adjust linker invocation for GNUToolsSaleem Abdulrasool1-7/+10
Adjust the driver to invoke the linker more similar to gcc. -dynamic-linker is only passed if -static and -shared are not part of the compiler (driver) invocation. Replicate the passing of -export-rdynamic as per the GCC link spec: %{!static: %{rdynamic:-export-dynamic} %{!shared:-dynamic-linker ...}} This behaviour is consistent across all the targets that are supported, so no need to conditionalise it on the target. Resolves PR24245. llvm-svn: 260019
2016-02-04[PGO] cc1 option name change for profile instrumentationRong Xu1-4/+6
