llvm dev - Aug 2014 - [LLVMdev] AARCH64 - compiler-rt missing some functions

Hi

Does anyone have a plan of attack for some things which libgcc is 
providing on AARCH64, but compiler-rt isn't yet?

We're hitting some Fortran issues with quad bits missing in glibc as a 
result.

Specifically this list
__addtf3
__eqtf2
__extenddftf2
__extendsftf2
__fixtfdi
__fixtfsi
__floatditf
__floatsitf
__gcc_qadd
__gcc_qdiv
__gcc_qmul
__gcc_qsub
__getf2
__gttf2
__letf2
__lttf2
__subtf3
__trunctfdf2
__trunctfsf2
__unordtf2

Comments/feedback appreciated. I'd like to get this upstream into 
compiler-rt asap.

./C

Has a pending review, needs a bit work before commit.

Those are only used on PPC for the double-double format?

2nd round of missing stuff in compiler-rt which is just waiting for review

The code is pretty small - Can someone please review those patches and 
push it. This blocks quad math stuff on aarch64 from using compiler-rt 
instead of gnu libgcc

__fixtfsi
__fixunstfsi
__floatsitf
__floatunsitf
