ugly testcase failing in {*movhi_aarch64}
I am not creating a separate PR for this, since the testcase is quite long, but
it might be useful for you.
$ aarch64-unknown-linux-gnu-gcc -O2 -ffast-math testcase.c -w
testcase.c: In function 'foo0':
testcase.c:36:1: error: insn does not satisfy its constraints:
36 | }

(insn 46 190 191 2 (set (reg:HI 4 x4 [172])
(mem/v/j/c:HI (plus:DI (reg/f:DI 6 x6 [96])
(const_int -257 [0xfffffffffffffeff])) [1 +0 S2 A8]))
"testcase.c":21:17 68 {*movhi_aarch64}
(nil))
during RTL pass: reload
