NAKAMURA Takumi 24fa47b541 BackendUtil.cpp: Add #include "llvm/TargetTransformInfo.h"
llvm/Target/TargetMachine.h will not provide "llvm/TargetTransformInfo.h" any more.

Bill Wendling 9a12912c9a Specify if `-mno-red-zone' was used when creating the GCOV instrucmentation pass.
This prevents the functions generated by that pass from using the red zone.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Alexey Samsonov 9ab73626fc Add Clang flags -fsanitize-blacklist and -fno-sanitize-blacklist. Make this flag usable for ASan. Blacklisting can be used to disable sanitizer checks for particular file/function/object.

Alexey Samsonov 0e96becfb1 This patch exposes to Clang users three more sanitizers are experimental features of ASan:
1) init-order sanitizer: initialization-order checker.
Status: usable, but may produce false positives w/o proper blacklisting.
2) use-after-return sanitizer
Status: implemented, but heavily understed.
Should be optional, as it significanlty slows program down.
3) use-after-scope sanitizer
Status: in progress.

Lang Hames 65992f454c Make -ffp-contract a codegen option, rather than a laguage option. This makes
more sense anyway - it determines how expressions are codegen'd. It also ensures
that -ffp-contract=fast has the intended effect when compiling LLVM IR.

Nadav Rotem dc06b2d39d Clang now attempts to create a TargetMachine whenever a triple is given.
Many of our tests specify triples that are not built into clang.
In this commit we allow clang to fail loading the triple if we are only
using clang to emit llvm ir.

Daniel Dunbar aa437df90a IRgen: Initialize TargetLoweringInfo with a triple.
- We create two TargetLoweringInfo instances for different pass managers, and
   they weren't consistent (the one for codegen didn't have the right info). I'm
   not sure this mattered anywhere in practice.

Bob Wilson 85f58c4152 Revert svn r165741 "Add TargetTransformInfo to the clang driver."

Lang Hames aa53b936ec Add -ffp-contract = { fast | on | off } command line option support.
This flag sets the 'fp-contract' mode, which controls the formation of fused
floating point operations. Available modes are:

- Fast: Form fused operations anywhere. 
- On: Form fused operations where allowed by FP_CONTRACT. This is the default
      mode.
- Off: Don't form fused operations (in future this may be relaxed to forming
       fused operations where it can be proved that the result won't be
       affected).

Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off'
modes are equivalent.

Rafael Espindola 66aa045fd9 Add a -fuse-init-array option to cc1 and map to the UseInitArray target
option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.

Chandler Carruth 097d019c6c Wire up -fpie and -fPIE to LLVM's newly added TargetOptions. No test
case as we don't currently have any way of dumping target options or
otherwise observing this. Another small step toward fixing PR12380. With
this we generate TLS accesses using the static model instead of the
dynamic model, but we're still generating suboptimal code under the
mistaken assumption that the TLS offset might be greater than 2^32, and
therefor not viable as an immediate offset of a segment register.

Kostya Serebryany 28a7a1198b Add a flag -fthread-sanitizer.
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423.
The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer.
This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet
committed and it's structure in compiler-rt is not 100% clear.
The users manual wil be changed in a separate commit.

Chad Rosier b1cfc6864f Allocate TargetLibraryInfo for the CodeGen passes. Otherwise, it's instantiated
by the BAA pass, which uses the default TargetLibraryInfo constructor.
Unfortunately, the default TargetLibraryInfo constructor assumes all library
calls are available and thus ignores -fno-builtin.

Bob Wilson 14adb360a7 Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325>
That llvm change removed the -trap-func backend option, so that using
-ftrap-function with clang would cause the backend to complain.  Fix it
by adding the trap function name to the CodeGenOptions and passing it through
to the TargetOptions.
