Bug ID: 116421 Summary: s390: vector-subscript-4.c FAILS on z16 Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: mpolacek at gcc dot gnu.org Target Milestone: --- Running c-c++-common/vector-subscript-4.c with -march=z13 up to -march=z16 results in: FAIL: c-c++-common/vector-subscript-4.c -Wc++-compat scan-tree-dump-not optimized "vector" It can be seen e.g. here https://gcc.gnu.org/pipermail/gcc-testresults/2024-August/821419.html. We generate: ``` int foo2 (int x, v2si v) { int _1; int _2; int _3; int _7; vector(2) int _8; <bb 2> [local count: 1073741824]: _1 = BIT_FIELD_REF <v, 32, 0>; _2 = BIT_FIELD_REF <v, 32, 32>; _3 = _1 ^ _2; BIT_FIELD_REF <v, 32, 0> = _3; _8 = v; _7 = .VEC_EXTRACT (_8, x_6(D)); return _7; } ```
