9054213d30 This patch implements runtime Mips specific
setting of ELF header e_flags.

7cd7b1f749 This patch reworks how llvm targets set
and update ELF header e_flags.

Currently gathering information such as symbol, 
section and data is done by collecting it in an 
MCAssembler object. From MCAssembler and MCAsmLayout 
objects ELFObjectWriter::WriteObject() forms and 
streams out the ELF object file.

This patch just adds a few members to the MCAssember 
class to store and access the e_flag settings. It 
allows for runtime additions to the e_flag by 
assembler directives. The standalone assembler can 
get to MCAssembler from getParser().getStreamer().getAssembler().

This patch is the generic infrastructure and will be
followed by patches for ARM and Mips for their target 
specific use.

042547700a Add a warning when there is a macro defintion that has named parameters but
the body does not use them and it appears the body has positional parameters.

This can cause unexpected results as in the added test case.  As the darwin
version of gas(1) which only supported positional parameters, happened to
ignore the named parameters.  Now that we want to support both styles of
macros we issue a warning in this specific case.

3f50a8d5c0 This is a resubmittal. For some reason it broke the bots yesterday
but I cannot reproduce the problem and have scrubed my sources and
even tested with llvm-lit -v --vg.
Support for Mips register information sections.

Mips ELF object files have a section that is dedicated
to register use info. Some of this information such as
the assumed Global Pointer value is used by the linker
in relocation resolution.

The register info file is .reginfo in o32 and .MIPS.options
in 64 and n32 abi files.

This patch contains the changes needed to create the sections,
but leaves the actual register accounting for a future patch.

2e875dfb6d We want the dwarf AT_producer for assembly source files to match clang's
AT_producer.  Which includes clang's version information so we can tell
which version of the compiler was used.

This is the first of two steps to allow us to do that.  This is the llvm-mc
change to provide a method to set the AT_producer string.  The second step,
coming soon to a clang near you, will have the clang driver pass the value
of getClangFullVersion() via an flag when invoking the integrated assembler
on assembly source files.

d66ed8368e This patch tackles the problem of parsing Mips
register names in the standalone assembler llvm-mc.

Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.


The problem is resolved by the Mips specific AsmParser 
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.

a2153405de PowerPC: EH adjustments
This patch adjust the r171506 to make all DWARF enconding pc-relative
for PPC64. It also adds the R_PPC64_REL32 relocation handling in MCJIT
(since the eh_frame will not generate PIC-relative relocation) and also
adds the emission of stubs created by the TTypeEncoding.

7af95b6c84 Fix suffix handling for parsing and printing of cvtsi2ss, cvtsi2sd, cvtss2si, cvttss2si, cvtsd2si, and cvttsd2si to match gas behavior.
cvtsi2* should parse with an 'l' or 'q' suffix or no suffix at all. No suffix should be treated the same as 'l' suffix. Printing should always print a suffix. Previously we didn't parse or print an 'l' suffix.
cvtt*2si/cvt*2si should parse with an 'l' or 'q' suffix or not suffix at all. No suffix should use the destination register size to choose encoding. Printing should not print a suffix.

Original 'l' suffix issue with cvtsi2* pointed out by Michael Kuperstein.
