The /GS- flag is used to turn off run-time buffer security checks (/GS).
Since no such checks are enabled in the first place, I think we should just
ignore this flag.

The test builds an object file to be able to get into linking mode
with a valid obj file on the command-line. Using clang-cl for this,
which targets win32, caused problems on some buildbots, so just
use regular clang.
llvm-svn: 190829
Previously we would warn about unused arguments such as /MD when linking.
Clang already has logic to ignore compile-only options, e.g. for -D and -U.
This patch extends that to include clang-cl's compile-only options too.
Also, some clang-cl options should always be ignored. Doing this earlier
means they get ignored both for compilation and link-only invocations.
llvm-svn: 190825
Apparently folks run into this (PR17097). The flag is not supported by
MSVC either, but we should parse it so we don't get confused when it occurs.
This changes the clang-cl output for "clang-cl /c /o foo.obj" from:
clang-cl.exe: error: no such file or directory: '/o'
clang-cl.exe: error: no such file or directory: 'foo.obj'
to:
clang-cl.exe: warning: argument unused during compilation: '/o bajs.obj'
llvm-svn: 190323
I don't think Clang intends to implement this functionality.
ASan should be used instead. Since /RTC is often passed by default
from MSBuild, ignore the option to avoid bloating the output.
llvm-svn: 190202
Clang doesn't have a table mapping cl.exe to clang warnings. While some
warnings like -Wsign-compare exist in both compilers, the majority do
not correspond and should usually be ignored.

This option prints information about #included files to stderr. Clang could
already do it, this patch just teaches the existing code about the /showIncludes
style and adds the flag.

These flags set some preprocessor macros and injects a dependency
on the runtime library into the object file, which later is picked up
by the linker.
This also adds a new CC1 flag for adding a dependent library.

This implements support for the /Fo option, which is used
to set the filename or output dir for object files.

These are used to specify source files, and whether to treat source
files as C or C++.

The original commit was reverted in r187640 after it broke the Mac build.
This should now be fixed, by Clang r187668, LLVM r187675, and putting
a -- before %s in the test.

It broke the "phase1 - sanity" buildbot. Reverting until
we can figure out what's going on.
And Eric says it broke all current Mac builds actually.

This adds a bunch of options to clang-cl. Notably, this includes
all the options that get passed when doing a default build of a
command-line project with msbuild.exe in Debug and Release modes,
and I believe all flags from Reid's original patch.

This adds a few more clang-cl options. It also exposes two core clang
options to the clang-cl mode: we need to be able to claim --driver_mode
so it doesn't show up as unused in cl mode, and we need -### for tests.
