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.

f36167d718 This patch produces the correct pointer size
value in the 64 bit .eh_frame section.

It doesn't however allow exception handling to work
yet since it depends on the correct relocation model

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.

5420e6ae4a Add a largish auto-generated test for the aligned bundling feature, along with
the script generating it. The test should never be modified manually. If anyone
needs to change it, please change the script and re-run it.

The script is placed into utils/testgen - I couldn't think of a better place,
and after some discussion on IRC this looked like a logical location.
