Roman Divacky a93d002321 Instead of explicitely comparing both lowercase and uppercase variants.
.lower() the Name and compare only the lowecase. Removing 81 compares/lines of
code. This changes the accepted string to be mixed lower/upper case but it
should be ok.

Reid Kleckner da0acc816c Revert "Change -save-temps to emit unoptimized bitcode files."
This reverts commit r224503.

It broke compilation of fortran through the Clang driver. Previously
`clang -c t.f` would invoke `gcc t.f` and `clang -cc1as`, but now it
tries to call `clang -cc1 t.f` which fails for obvious reasons.

Jean-Daniel Dupas 23dd15e26d [macho] -rpath support
Summary:
Work on adding -rpath support to the mach-o linker.
This patch is based on the ld64 behavior for the command line option validation.

It includes a basic test to check that the LC_RPATH load commands are properly generated when that option is used.

It also add LC_RPATH support to the binary reader, but I don't know how to test it though.

Zachary Turner f27ae73617 Always use python-based SWIG generation script for CMake.
As a first step in addressing Bug #21921 this patch prefers
the python-based SWIG generation by default rather than the
shell-based SWIG generation any time python is enabled
(e.g. LLDB_DISABLE_PYTHON is 0).

Additionally, this patch changes the default value of
LLDB_DISABLE_PYTHON from 1 to 0 on Windows.

Anyone not using the CMake build is unaffected by this patch.

Stephane Sezer b743a8034f Display local kernel version only when non-remote in PlatformLinux.
Summary:
This is part of the Linux remote platform work. Displaying the local
kernel information when remote debugging doesn't make sense, so we
should verify if we are in host mode before doing so.

Test Plan:
Connect to a remote linux platform mode daemon with `platform select
remote-linux` followed by `platform connect ...`, and look at the output
of `platform status`.

Repared support for warnings -Wkeyword-macro and -Wreserved-id-macro.
The warning -Wkeyword-macro now is not issued in patterns that are used
in configuration scripts:

    #define inline

also for 'const', 'extern' and 'static'. If macro repalcement is identical
to macro name, the warning also is not issued:

    #define volatile volatile

And finally if macro replacement is also a keyword identical to the replaced
one but decorated with leading/trailing underscores:

    #define inline __inline
    #define inline __inline__
    #define inline _inline // in MSVC compatibility mode

Warning -Wreserved-id-macro is off by default, it could help catching

David Majnemer 2d3663e559 Parse: Don't parse after the eof has been consumed
ParseCXXNonStaticMemberInitializer stashes away all the tokens for the
initializer and an additional EOF token to denote where the initializer
ends.  However, it is possible for ParseLexedMemberInitializer to get
its hands on the "real" EOF token; since the two tokens are
indistinguishable, we end up consuming the EOF and descend into madness.

Instead, make it possible to tell which EOF token we are looking at.

This fixes PR21872.

Bob Wilson f5ba8288ad Change -save-temps to emit unoptimized bitcode files.
It is often convenient to use -save-temps to collect the intermediate
results of a compilation, e.g., when triaging a bug report. Besides the
temporary files for preprocessed source and assembly code, this adds the
unoptimized bitcode files as well.

This adds a new BackendJobAction, which is mostly mechanical, to run after
the CompileJobAction. When not using -save-temps, the BackendJobAction is
combined into one job with the CompileJobAction, similar to the way the
integrated assembler is handled. I've implemented this entirely as a
driver change, so under the hood, it is just using -disable-llvm-optzns
to get the unoptimized bitcode.

Based in part on a patch by Steven Wu.
