--- Comment #1 from Oleg Endo <olegendo at gcc dot gnu.org> ---
I've tried this issue on latest version of the SH LRA branch
https://github.com/olegendo/gcc/tree/devel/sh-lra
The issue still persists. Note that the above case must be compiled as C++.
If compiled as C, the code contains a redundant mode switch, see PR 116849
without LRA:
mova .L4,r0
fmov.s @r0+,fr2
fmov.s @r0+,fr1

fmov fr2,fr0

.align 2

with LRA:
