Modified Files: src/external/gpl3/gcc/dist/gcc/config/rs6000: rs6000.c Log Message: Fix regression introduced to GCC10, where it wrongly recognizes 32-bit processors as POWER9 if -misel flag is specified. rs6000_machine_from_flags() assumes ISEL instructions are supported only for POWER9 and successors. However, ISEL is also implemented for 32-bit booke processors. Since our kernel for booke is compiled with -misel, this regression completely breaks it. As a fix, check whether CPU is 64-bit capable or not, before checking -misel flag. The problem has been reported as 100108 to upstream: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100108 OK mrg To generate a diff of this commit: cvs rdiff -u -r1.25 -r1.26 \ src/external/gpl3/gcc/dist/gcc/config/rs6000/rs6000.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
