--- Comment #4 from Sam James <sjames at gcc dot gnu.org> --- Created attachment 57409 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57409&action=edit udataswp.ii.xz It goes wrong in common/udataswp.cpp's uprv_copyArray16 and uprv_copyArray64. (Seemingly both of them need to be pragma'd but I'll check again later as it's a bit weird.) The first differing pass is 262r.expand. ``` [...] -(insn # # # (set (reg:CC 17 flags) - (compare:CC (reg:SI 133) - (const_int 8 [0x8]))) "udataswp.cpp":173:9# - (nil)) - -(jump_insn # # # (set (pc) - (if_then_else (ltu (reg:CC 17 flags) - (const_int 0 [0])) - (label_ref #) - (pc))) "udataswp.cpp":173:9# - (int_list:REG_BR_PROB 644245100 (nil))) [...] @@ -6876,15 +6862,11 @@ Merged 2 and 3 without moving.
