search for: __subtf3

Is the llvm backend (legalize, isel, etc.) currently capable of handling type f128? I am trying to emit a call to __subtf3 when I compile the following bitcode: define fp128 @f1(fp128 %a0, fp128 %a1) nounwind readnone { entry: %sub = fsub fp128 %a0, %a1 ret fp128 %sub } This is for the Mips backend.

There is some generic code here and there which can handle f128, but some parts are still missed. You might need to fill them... -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

...ompiler-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
