Here&there I find the likes of mulqi3.S & divmodhi4.S.
Is there a reference anywhere on gnu.org on how to browse current official revisions of such architecture specific source code? What is the relation to LLVM?
If not, can you point me to a current resource? Download, if browsing is not supported.
What do "they" use for regression testing architecture specific routines;
is there something I could easily use myself?
