Joerg Sonnenberger ec353d3fc6 Reorganise CPU handling for Sparc. When using -mcpu=v9 and co, __sparcv8
is not defined for 32bit mode, but __sparcv9 is. Pass down the correct
-target-cpu flags to the backend, so that instruction restrictions are
applied correctly. Pass down the correct -A flag when not using IAS.
The latter is limited to NetBSD targets in this commit.

Renato Golin 4854d80c39 [EABI] Add Clang support for -meabi flag
The -meabi flag to control LLVM EABI version.

Without '-meabi' or with '-meabi default' imply LLVM triple default.
With '-meabi gnu' sets EABI GNU.
With '-meabi 4' or '-meabi 5' set EABI version 4 and 5 respectively.

A similar patch was introduced in LLVM.

John McCall 460ce58fa6 Define weak and __weak to mean ARC-style weak references, even in MRC.
Previously, __weak was silently accepted and ignored in MRC mode.
That makes this a potentially source-breaking change that we have to
roll out cautiously.  Accordingly, for the time being, actual support
for __weak references in MRC is experimental, and the compiler will
reject attempts to actually form such references.  The intent is to
eventually enable the feature by default in all non-GC modes.
(It is, of course, incompatible with ObjC GC's interpretation of
__weak.)

If you like, you can enable this feature with
  -Xclang -fobjc-weak
but like any -Xclang option, this option may be removed at any point,
e.g. if/when it is eventually enabled by default.

This patch also enables the use of the ARC __unsafe_unretained qualifier
in MRC.  Unlike __weak, this is being enabled immediately.  Since
variables are essentially __unsafe_unretained by default in MRC,
the only practical uses are (1) communication and (2) changing the
default behavior of by-value block capture.

As an implementation matter, this means that the ObjC ownership
qualifiers may appear in any ObjC language mode, and so this patch
removes a number of checks for getLangOpts().ObjCAutoRefCount
that were guarding the processing of these qualifiers.  I don't
expect this to be a significant drain on performance; it may even
be faster to just check for these qualifiers directly on a type
(since it's probably in a register anyway) than to do N dependent
loads to grab the LangOptions.

easily and make it consistent with Darwin toolchain (a TODO was
added for this refactoring - now removed). A new helper method
is also introduced to test if instrumentation profile option
is turned on or not.

Saleem Abdulrasool 436256a713 Support Debug Info path remapping
Add support for the `-fdebug-prefix-map=` option as in GCC.  The syntax is
`-fdebug-prefix-map=OLD=NEW`.  When compiling files from a path beginning with
OLD, change the debug info to indicate the path as start with NEW.  This is
particularly helpful if you are preprocessing in one path and compiling in
another (e.g. for a build cluster with distcc).

Note that the linearity of the implementation is not as terrible as it may seem.
This is normally done once per file with an expectation that the map will be
small (1-2) entries, making this roughly linear in the number of input paths.

environments.  This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword.  Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and

Windows on ARM ABI uses the FP for fast stack walking.  By paying the slight
cost of the loss of registers, a much faster backtrace is possible by using the
frame pointer since the pdata need not be consulted.  Furthermore, even if pdata
is not available, you can still more easily reconstruct the stack.

Bruno Cardoso Lopes a5efe3a66b [DarwinDriver] Reapply: Use -lto_library to specify the path for libLTO.dylib
Reapply r248935.

Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.

However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

Vasileios Kalintiris 712f0887f6 Add support for the new mips-mti-linux toolchain.
Summary:
This new toolchain uses primarily LLVM-based tools, eg. compiler-rt, lld,
libcxx, etc. Because of this, it doesn't require neither an existing GCC
installation nor a GNU environment. Ideally, in a follow-up patch we
would like to add a new --{llvm|clang}-toolchain option (similar to
--gcc-toolchain) in order to allow the use of this toolchain with
independent Clang builds. For the time being, we use the --sysroot
option just to test the correctness of the paths generated by the
driver.

Summary:
This patch moves getCompilerRT() from the clang::driver::tools namespace to
the ToolChain class. This is needed for multilib toolchains that need to
place their libraries in Clang's resource directory with a layout that is
different from the default one.

Saleem Abdulrasool d44901f21b Driver: support ARM/HF on a single toolchain
ARM EABI adds target attributes to the object file.  Amongst the attributes that
are emitted is the VFP argument passing (Hard vs Soft).  The linker is
responsible for checking these attributes and erroring on mismatches.  This
causes problems for the compiler-rt builtins when targeting both hard and
soft.  Because both of these options name the builtins compiler-rt component
the same (libclang_rt.builtins-arm.a or libclang_rt.builtins-arm-android).  GCC
is able to get away with this as it does one target per toolchain.  This
changes the naming convention for the ARM compiler-rt builtins to differentiate
between HF and Soft.  Although this means that compiler-rt may be duplicated, it
enables supporting both variants from a single toolchain.  A similar approach is
taken by the Darwin toolchain, naming the library to differentiate between the
calling conventions.

Eric Christopher 74a7c5dc16 The Clang gcc-compatible driver (clang/tools/driver/driver.cpp) has some
logic to select an alternate target based on the executable it was
called as. For instance, if you symlink i686-linux-android-gcc to clang
and invoke it, the driver will act as though it were called with another
argument ("-target i686-linux-android"). This leads to visible effects
even in syntax-only compilations (like the ANDROID preprocessor symbol
being defined).

This behavior is not replicated for tool invocations--for instance,
clang::createInvocationFromCommandLine will not choose an alternate
target based on ArgList[0]. This means that configurations stored in
compilation databases aren't accurately replayed.

This patch separates the logic for selecting a mode flag and target from
the executable name into a new member function on ToolChain. It should
have no functional effects (but will allow other code to reuse the
target/mode selection logic).

Xcode 7 doesn't support targeting iOS5 and earlier. Instead of just dropping cc_kext_ios5, I've repurposed it to cc_kext_ios, and I'm pulling the iOS architectures out of cc_kext. Putting OS X and iOS slices inside the same archive was just odd.
