- This is pretty ugly, but the most obvious solution. Chime in if you
have a nicer one.
- The problem is that with -save-temps, clang-cc has no idea what the
name of the original input file is. However, the user expects to be
able to set breakpoints based on the input file name.
- We support this by providing a new option -main-file-name (similar
to -dumpbase used by gcc) which allows the driver to pass in the
original file name.
- <rdar://problem/6753383> building with clang using --save-temps
gets the compile unit name from the .i file...
llvm-svn: 68595
- Add -pic-level clang-cc option to specify the value for the define,
updated driver to pass this.
- Added __pic__
- Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc).

clang.
- We will eventually want some more driver infrastructre for this
probably.
- For now, the clang-cc interface stays relatively the same, but we
don't accept multiple instances anymore, or the [no-] variants
directly.
llvm-svn: 68550
- Ignore some more -W options and -[fm] options which we can somewhat
safely ignore.
- Recognize that -W is an alias for -Wextra
W: -Wdeclaration-after-statement -Werror-implicit-function-declaration -Wfour-char-constants -Winit-self -Wmissing-format-attribute -Wno-#warnings -Wno-comment -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Wstrict-prototypes -Wunused-parameter

preceeded by a linker input flag.
- <rdar://problem/6757236> clang should make a dSYM when going
straight from source to binary
- This still matches gcc, but the right way to solve this would be to
detect the situation we care about (we are compiling from source
and linking in one step), instead of looking at the suffix of the
input file. The Tool doesn't quite have enough information to do
this yet, however.
- Also, find the suffix correctly.
llvm-svn: 68417
the preprocessor.
- PR3602.
- As is inherent in the blanket forwarding options, this will only
work if clang-cc happens to accept what the user passed. Users by
and large should use driver options to interact with the
preprocessor, if at all possible.
llvm-svn: 68144
- Rip out various bits of logic from clang-cc's dependency file gen,
force driver to provide instead.
- -MD output now goes to proper location
<rdar://problem/6723948> clang -MD puts dep file in /tmp with wrong name
- -M and -MM still don't work correctly.
llvm-svn: 68022
turned into -m[no-]pascal-strings by the tool chain.
- This still has issue that derived arguments don't propogate "used"
information correctly so spurious "argument unused" warnings will
still show up.
llvm-svn: 67841
- -emit-llvm no longer changes what compilation steps are done.
- -emit-llvm and -emit-llvm -S write output files with .o and .s
suffixes, respectively.
- <rdar://problem/6714125> clang-driver should support -O4 and -flto,
like llvm-gcc

clang doesn't support, and don't want to warn are unused. Eventually
these should disappear.
Here is a more readable list than is in the diff:
W options: -Wall, -Wcast-align, -Wchar-align, -Wchar-subscripts,
-Werror, -Wextra, -Winline, -Wint-to-pointer-cast, -Wmissing-braces,
-Wmost, -Wnested-externs, -Wno-format-y2k, -Wno-four-char-constants,
-Wno-missing-field-initializers, -Wno-trigraphs, -Wno-unknown-pragmas,
-Wno-unused-parameter, -Wparentheses, -Wpointer-arith,
-Wpointer-to-int-cast, -Wreturn-type, -Wshorten-64-to-32, -Wswitch,
-Wunused-function, -Wunused-label, -Wunused-value, -Wunused-variable,
-Wwrite-strings.
f options: -fasm-blocks, -fmessage-length=.
llvm-svn: 67549
are forwarded to GCC.
- The later is unfortunate, as it prevents us from generally warning
about anything interesting on platforms that use a generic
toolchain. However, we can't do much better without significantly
complicating things, and generally we should have proper tool chain
definitions.
llvm-svn: 67293
if our usual methods fail. This isn't necessary for running the tool,
but improves the accuracy of logging output.
Also, have GCC tools lookup gcc program path.
