Bug ID: 121612
Summary: RISC-V: r16-2451-g4b62bd519a852a makes tests
unresolved
Product: gcc
Version: 15.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: parras at gcc dot gnu.org
Target Milestone: ---
4b62bd519a8 RISC-V: testsuite: Fix vx_vf_*run-1-f16.c run tests.
The CI output log [1] shows:
UNSUPPORTED: gcc.target/riscv/rvv/autovec/vx_vf/vf_vfmacc-run-1-f16.c
-ftree-vectorize -O3 -mrvv-vector-bits=scalable -mrvv-max-lmul=m4 -ffast-math

--param=fpr2vr-cost=0 -lm -o ./vf_vfmacc-run-1-f32.exe
and similar for all tests affected by this patch.
The CI summary [2] lists those tests as "resolved failures" because they are
not failing any more, but they actually never run.
The root cause is likely the combination of:
/* { dg-require-effective-target riscv_zvfh } */
in each testcase, and the definition of:
proc check_effective_target_riscv_zvfh_ok
in target-supports.exp [3].
The log shows that check_effective_target_riscv_zvfh fails but the
check_runtime part seems to never run.
Also, probably unrelated, but these lines appear twice:
proc remove_options_for_riscv_zvfh { flags } {
return [add_options_for_riscv_z_ext zvfh $flags]
}
