This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target. Note that at this point, the target
cannot yet be built since the configure bits are missing. Those
will be provided shortly by a follow-on patch.
This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov. Thanks to all reviewers!

We've added the RS880 variant in the LLVM backend to represent an R600
GPU with no vertex cache, so we need to update the GPU mappings for
-mcpu.

This is another patch in preparation for adding the SystemZ target.
It defines the appropriate values for DWARF encodings; the intent
is to be compatible with what GCC currently does on the target.

Several platforms need to disable all old-JIT unit tests, since they only
support the new MCJIT. This currently done via #ifdef'ing out those tests
in the ExecutionEngine/JIT/*.cpp files. As those #ifdef's have grown
historically, we now have a number of repeated directives which -in total-
cover nearly the whole file, but leave a couple of helper functions out.
When building the tests with clang itself, those helper functions now
cause spurious "unused function" warnings.
To fix those warnings, and also to remove the duplicate #ifdef conditions
and make it easier to disable the tests for a new target, this patch
consolidates the #ifdefs into a single one per file, which covers all
the tests including all helper routines.
Tested on PowerPC and SystemZ.

As pointed out by Evgeniy Stepanov, assigning a std::string temporary
to a StringRef is not a good idea. Rework MatchRegisterName to avoid
using the .lower routine.

LLVM/Clang basically don't use such comments and for Google-style,
include-lines are explicitly exempt from the column limit. Also, for
most cases, where the column limit is violated, the "better" solution
would be to move the comment to before the include, which clang-format
cannot do (yet).
llvm-svn: 181191
clang-format did not indent any declarations/definitions when breaking
after the type. With this change, it indents for all declarations but
does not indent for function definitions, i.e.:
Before:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }
After:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }
While it might seem inconsistent to indent function declarations, but
not definitions, there are two reasons for that:
- Function declarations are very similar to declarations of function
type variables, so there is another side to consistency to consider.
- There can be many function declarations on subsequent lines and not
indenting can make them harder to identify. Function definitions
are already separated by their body and not indenting
makes the function name slighly easier to find.

This seems to be more common in LLVM, Google and Chromium.
Before:
class AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA :
public BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB,
public CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC {
};
After:
class AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
: public BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB,
public CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC {
};

We used to disable constant merging not only if a constant is llvm.used, but
also if an alias of a constant is llvm.used. This change fixes that.
llvm-svn: 181175
This gets exception handling working on ELF and Macho (x86-64 at least).
Other than the EH frame registration, this patch also implements support
for GOT relocations which are used to locate the personality function on
MachO.

I was not able to find a case (other than the fix in r181163) where this
makes a difference, but it is a more obviously correct API to have.

indirect branch at the end of the BB. Otherwise if-converter, branch folding
pass may incorrectly update its successor info if it consider BB as fallthrough
to the next BB.
