...brary (http://www.etalabs.net/musl/) for my ELLCC (http://ellcc.org) cross compiler project. During my musl feasability study I made a Mips port of musl. A day or two ago, just to make things interesting, I updated to the LLVM TOT (r158294). I started getting assembler warnings about ".set nomicromips". I'm running a fairly recent binutils (2.21.1). My questions are: 1. Does the code generator really need to output ".set nomicromips"? 2. Does a more recent version of binutils understand it? -Rich

I have these statements left to translate. Most we already discussed. .align 2 the .nomips16 and .nomicromips we have it in mipsTargetStreamer (which to me seems little different from emit raw text). I think you mentioned already how to do the .size OutStreamer.EmitRawText(".align 2"); OutStreamer.EmitRawText(".nomips16"); OutStreamer.EmitRawText(".nomicromips");...

I am not saying that the functions should not exist in the IL, just that they should not be inline
