--- Comment #374 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- Created attachment 59286 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59286&action=edit a patch for c#367 We use movsf_ie as a fall-back for for moving fp-reg from/to multiword subreg in 59190. Looks this confuses LRA with the SI mode scratch constrained to "y". The patch uses a new pattern instead of movsf_ie. It's a mini movsf_ie in a sense but with the SFmode scratch. Tested only with target libgcc/libstdc++v3 build and c testsuite.
