--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Confirm.  But option save/restore has been always implemented:

    .section    .gnu.lto_.opts,"",@progbits
    .ascii  "'-fno-openmp' '-fno-openacc' '-fno-pie' '-fcf-protection"
    .ascii  "=3Dnone' '-mabi=3Dlp64d' '-march=3Dloongarch64' '-mfpu=3D64' '=
-m"
    .ascii  "simd=3Dlasx' '-mcmodel=3Dnormal' '-mtune=3Dloongarch64' '-flto"
    .ascii  "'\000"

So -msimd=3Dlasx is correctly recorded.  Not sure why it does not work.=
