--- Comment #27 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 45566 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45566&action=edit gcc9-pr88714.patch Untested full patch, will try to bootstrap it now on armv7hl, no access to other variants though. A few GCC10 backend cleanup comments - "" constraints in match_operand should be omitted, it would be nice to replace GET_CODE (x) == REG or GET_CODE (x) != MEM etc. tests with REG_P (x) or !MEM_P (x) etc. and the formatting is sometimes quite weird.
