Bug ID: 113533 Summary: [14 Regression] Code generation regression after change for pr111267 Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: rtl-optimization Assignee: unassigned at gcc dot gnu.org Reporter: law at gcc dot gnu.org Target Milestone: --- sh3-linux-gnu or sh3eb-linux-gnu is showing a code generation regression after the changes for pr111267. test_01 with -O1 shows the problem nicely: int test_01 (unsigned char* a) { /* 1x cmp/pz, 1x addc */ return a[0] + (a[0] < 128); } Before: test_01: mov.b @r4,r1 extu.b r1,r0 cmp/pz r1 mov #0,r1 rts addc r1,r0 After: test_01: mov.b @r4,r0 extu.b r0,r0 mov.b @r4,r1 cmp/pz r1 mov #0,r1 rts addc r1,r0 Note the extra memory load. I'm not actively working on this.
