We didn't switch to LLVM.clang because of some gcc <-> kernel issue. On that time when we decided on this, i think we were not even aware of that bug.
IIRC kernel is not yet ready at least official branch to be compiled with clang. I'm not an kernel expert but CONFIG_CC_OPTIMIZE_FOR_SIZE set to y (not default value) may bring more bad rather good effects. 2014-07-28 11:23 GMT+02:00 Jeffrey Johnson <[email protected]>: > > > On Jul 28, 2014, at 4:54 AM, Tomasz Paweł Gajc <[email protected]> wrote: > > > > Yes we switched from gcc to clang for CC and CXX.
