csanchezdll at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |csanchezdll at gmail dot com --- Comment #12 from csanchezdll at gmail dot com --- Seems to be still in SVN trunk. I have identified the problem and sent a patch: https://gcc.gnu.org/ml/gcc-patches/2015-07/msg00191.html Using newer cctools also solved the problem as newer gas versions support named parameters in macros, but with this patch updating cctools is not required.
