Bug ID: 113035
Summary: RISC-V: -mtune=sifive-7-series additional dump
failures found with bitmanip, zicond, and vector
targets
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ewlu at rivosinc dot com
Target Milestone: ---

testsuite failures for rv64 bitmanip and vector as of r14-6557-g767e2674875
I was testing different cpu/tunes for cleaning up the scheduler and saw that
there are significant differences in testsuite results between using
mtune=rocket (default) and mtune=sifive-7-series.
Most notably, there are many failures in gcc.target/riscv/rvv/vsetvl,
gcc.target/riscv/zicond-primitiveSemantics_compare_*.c, and some with zbb and
zbs.
