Summary:
cl.exe recognizes /o as a deprecated and undocumented option similar to
/Fe. This patch adds support for this option to clang-cl for /Fe, /Fo
and /Fi. It also ensures that the last option among /o and /F* wins,
if both specified.
This is required at least for building autoconf based software, since
autoconf uses -o to specify the executable output.
This fixes http://llvm.org/PR20894.
Test Plan: The patch includes automated tests.

actually different. Fixes a surprising link error with nodejs on rpi,
where armv6-netbsd-eabihf turned into armv5e-netbsd-eabihf, which
doesn't lacks the necessary VFP support.

It hits a limit when we reach ActionList, which is used for dynamic
conditional ownership, so we lose type safety there.
This did expose at least one caller "lying" about ownership (passing
ownership to an Action, then updating the Action to specify that it
doesn't actually own the thing that was passed) - changing this to
unique_ptr just makes that oddity more obvious.

This patch aims at fixing PR17239.
This bug happens because the /link (clang-cl.exe argument) is marked as
"consume all remaining arguments". However, when inside a response file,
/link should only consume all remaining arguments inside the response
file where it is located, not the entire command line after expansion.
The LLVM side of the patch will change the semantics of the
RemainingArgsClass kind to always consume only until the end of the
response file when the option originally came from a response file.
There are only two options in this class: dash dash (--) and /link.
This is the Clang side of the patch in http://reviews.llvm.org/D4899

This escapes any backslashes in the executable path and fixes an issue
with a trailing quote when the main file name had to be quoted during
printing.
It's impossible to test this without putting backslashes or quotes into
the executable path, so I didn't add automated tests.
The crash diagnostics are still only useful if you're using bash on
Windows, though. This should probably be writing a batch file instead.

The main subtlety here is that the Darwin tools still need to be given "-arch
arm64" rather than "-arch aarch64". Fortunately this already goes via a custom
function to handle weird edge-cases in other architectures, and it tested.
I removed a few arm64_be tests because that really isn't an interesting thing
to worry about. No-one using big-endian is also referring to the target as
arm64 (at least as far as toolchains go). Mostly they date from when arm64 was
a separate target and we *did* need a parallel name simply to test it at all.
Now aarch64_be is sufficient.

-mx32 flag setup target environment to GNUX32 and can be used for
other 32/64-bit triplets (i386-unknown-linux, x86_64-unknown-linux) to
turn on x32 mode. Compatible with GCC -mx32 flag.

It reverts commits as follows:
r211866: "Driver: use GNU::Link for the Generic_GCC toolchain"
r211895: "Replace GetProgramPath("ld") with GetLinkerPath()."
r211995: "Driver: add a cygwin linker tool"
llvm-svn: 211998
This adds a linker tool for the Windows cygwin environment. This linker
invocation is significantly different from the generic ld invocation. It
requires additional parameters as well as does not accept some normal
parameters. This should fix self-hosting on Cygwin.

When we create a crashdump involving modules, we build a VFS to
reproduce the problem with. This updates the reproduction script to
use that VFS.

It's more flexible and arguably better layering to set flags to modify
compiling for diagnostics in the CC1 job themselves, rather than
tweaking the driver flags and letting them propagate.
There is one visible change this causes: crash report files will now
get preprocessed names (.i and friends).

This corrects long-standing misuses of LLVM's internal config.h.
In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.
The config.h header is private, won't be installed and should no longer be
included by clang or other modules.

All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.
This also brings about the possibility of adapting the value based on the
driver's compatibility mode in future.
The setting can still be changed via Driver::DefaultImageName as needed.

This follows the LLVM change to canonicalise the Windows target triple
spellings. Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment. This is a
mechanical change to convert the triple use to reflect that change.

In gcc using -Ofast forces linking of crtfastmath.o.
In the current clang crtfastmath.o is only linked when -ffast-math/-funsafe-math-optimizations passed. It can lead to performance issues, when using only -Ofast without explicit -ffast-math (I faced with it).
My patch fixes inconsistency with gcc behaviour and also introduces few tests on it.

This patch improves the support for picking Multilibs from gcc installations.
It also provides a better approximation for the flags '-print-multi-directory'
and '-print-multi-lib'.
This reverts r201203 (i.e. re-applying r201202 with small fixes in
unittests/CMakeLists.txtto make the build bots happy).

Use the verify hook rather than the compile hook to represent the
-verify-pch action, and move the exising --verify-debug-info action
into its own subclass of VerifyJobAction. Incidentally change the name
printed by -ccc-print-phases for --verify-debug-info.
llvm-svn: 200938
This option will:
- load the given pch file
- verify it is not out of date by stat'ing dependencies, and
- return 0 on success and non-zero on error
