David Malcolm <dmalcolm at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andrea.corallo at arm dot com, | |dmalcolm at gcc dot gnu.org --- Comment #21 from David Malcolm <dmalcolm at gcc dot gnu.org> --- If you can reproduce this, please set comp-ctxt-debug to >= 3: emacs ought to write out a log to libgccjit.log (each invocation will overwrite the previous log file there); please attach the log to this bug. FWIW when I do this, my logfile has (among all kinds of other useful info): JIT: argv[10]: -mtune=generic JIT: argv[11]: -march=x86-64 so I don't think it's being affected by the machine its run on (but maybe emacs can customize this?)
