[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

[LLVMdev] [cfe-dev] AARCH64 - compiler-rt missing some functions
2nd round of missing stuff in compiler-rt which is just waiting for review --------------- http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140210/204960.html http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140210/204961.html 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
