Akira Hatanaka f47db38a01 [mips] Remove Triple:mips from SupportedArchs in MCJIT unittests 
MIPS does not handle multiple relocations correctly, so two tests from the
unittests are expected to fail. These are:
 - MCJITTest.return_global and
 - MCJITTest.multiple_functions.

Until the multiple relocations are fixed, XFAIL the MCJIT unittests for
MIPS. This issue is tracked as Bug 16250.

Patch by Petar Jovanovic.

Meador Inge dfb08a2cb8 Remove the simplify-libcalls pass (finally) 
This commit completely removes what is left of the simplify-libcalls
pass.  All of the functionality has now been migrated to the instcombine
and functionattrs passes.  The following C API functions are now NOPs:

  1. LLVMAddSimplifyLibCallsPass
  2. LLVMPassManagerBuilderSetDisableSimplifyLibCalls

Meador Inge f081d02586 CodeGen: Don't set 'PMBuilder.DisableSimplifyLibCalls' 
The simplify-libcalls pass has been removed from LLVM.  Thus
'PMBuilder.DisableSimplifyLibCalls' does not exist anymore.
The disabling/enabling of library call simplifications is
done through the TargetLibraryInfo which is already wired
up in Clang.

The old isNormal is already functionally replaced by the method isFiniteNonZero
in r184350 and all references to said method were replaced in LLVM/clang in
r184356/134366.

Joey Gouly f81d036ea7 This reverts r155000.

Ulrich Weigand 22dff957d4 [PowerPC] Add missing build dependency 
This (hopefully) fixes build failures resulting from r184436;
the PowerPC asm parser now depends on PowerPC target expresssions.

Reid Kleckner 5ca566fbdf Fix CodeGenCXX/debug-info.cpp test on Windows 
On Windows, it looks like FlagIndirectVariable is being set in Flags for
DIBuilder::createLocalVariable(), giving us an i32 of 8192 instead of 0,
as on Linux.

Fixes breakage from r184367.

Ulrich Weigand d412098f43 [MC] Support @ variants with directional labels 
The assembler parser common code supports recognizing symbol variants
using the @ modifer.  On PowerPC, it should also be possible to use
(some of) those modifiers with directional labels, like "1f@l".

This patch adds support for accepting symbol variants on directional
labels as well.

llvm-svn: 184437
 2013-06-20 16:24:17 +00:00
Ulrich Weigand 96e6578395 [PowerPC] Optimize @ha/@l constructs 
This patch adds support for having the assembler optimize fixups
to constructs like "symbol@ha" or "symbol@l" if "symbol" can be
resolved at assembler time.

This optimization is already present in the PPCMCExpr.cpp code
for handling PPC_HA16/PPC_LO16 target expressions.  However,
those target expression were used only on Darwin targets.

This patch changes target expression code so that they are
usable also with the GNU assembler (using the @ha / @l syntax
instead of the ha16() / lo16() syntax), and changes the
MCInst lowering code to generate those target expressions
where appropriate.

It also changes the asm parser to generate HA16/LO16 target
expressions when parsing assembler source that uses the
@ha / @l modifiers.  The effect is that now the above-
mentioned optimization automatically becomes available
for those situations too.

 2013-06-20 16:23:52 +00:00
Ulrich Weigand 865a1efc13 [PowerPC] Support compare mnemonics with implied CR0 
Just like for branch mnemonics (where support was recently added), the
assembler is supposed to support extended mnemonics for the compare
instructions where no condition register is specified explicitly
(and CR0 is assumed implicitly).

This patch adds support for those extended compare mnemonics.

Summary:
Fixes a problem where \t,\v or \f could lead to a crash when placed as

these characters, but our code didn't, so some invariants could be broken.
