Indeed on armv8 for example, gcc-12 aarch64 outputs:

.file "main.cpp"
.text
.align 2
.p2align 4,,11
.global test::is_std_nan(float)
.type test::is_std_nan(float), %function
test::is_std_nan(float):
.LFB2710:
fcmp s0, s0
cset w0, vs
ret
.LFE2710:
.size test::is_std_nan(float), .-test::is_std_nan(float)
.align 2
.p2align 4,,11
.global test::is_std_nan(double)
.type test::is_std_nan(double), %function
test::is_std_nan(double):
.LFB2711:
fcmp d0, d0
cset w0, vs
ret
.LFE2711:
