John McCall c84e4e9b1c Call __cxa_begin_catch before std::terminate() in a noexcept trap. 
r174939-40 caused us to do this in the canonical terminate lpad,
but when the EH stack has other cleanups on it we use the
terminate handler block, which wasn't doing this.

Fixes the rest of rdar://11904428 given appropriate stdlib support.

headers may be included from within the module, but not from outside

Sean Silva 05001b9f38 [yaml2obj][ELF] Add support for st_value and st_size. 
After this patch, the ELF file produced by
`yaml2obj-elf-symbol-basic.yaml`, when linked and executed on x86_64
(under SysV ABI, obviously; I tested on Linux), produces a working
executable that goes into an infinite loop!

Sean Silva c1c290b25e [yaml2obj][ELF] Add the section name -> section index map to State. 
One of the key things that the YAML format abstracts over is the use of
section numbers for referencing sections. Instead, textual section names
are used, which yaml2obj then translates into appropriate section
numbers. (Technically ELF doesn't care about section names (only section
numbers), but since this is a testing tool, readability counts).

This simplifies using section names as symbolic references in various
parts of the code. An upcoming commit will use this to allow symbols to
reference sections.

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.

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

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.

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.

 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.

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.
