I've been adding fixes to pass a ton of regression in the Generic folder. Currently there are two tests that fail with a "cannot select build_pair" related to adding 16bit reg classes in the inline asm code. The rest of failing tests are related with not being able to run llc with -O0. There's a serious codegen bug that i spotted yesterday while doing the fixes that I need to work on. 2013/7/22 Borja Ferrer <bor...@gm...> > Hello Stepan, > > 3) Yes, it's the second case.
