--- Comment #29 from Ilya Leoshkevich <iii at linux dot ibm.com> --- Created attachment 47463 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47463&action=edit nop plugin Hi Maxim, Just to clear my conscience, could you please try the nop trick in your setup? I normally use the attached plugin for that. Just build it and add e.g. -fplugin=$HOME/gcc-nop-plugin/libgcc_nop_plugin.so -fplugin-arg-libgcc_nop_plugin-S_regmatch=4 to the compiler flags. Best regards, Ilya
