Hello Vlad, Back in October, you added a patch to remove extra clobbers introduced by LRA: http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02531.html
This also disables some -frename-registers opportunities (a few 100 on x86-64 for my collection of cc1-i files). Do you think it's be possible (and worth the effort) to implement something that keeps clobbers for registers that are live above the clobber after removing the clobber? Ciao! Steven
