It seems a regression in GCC10. GCC9 is ok, https://godbolt.org/
GCC 9:
f1(float, float):
ucomiss xmm0, xmm1
jp .L4
jne .L4
ret
.L4:
jmp f()
f2(float, float):
ucomiss xmm0, xmm1
jnp .L11
.L7:
ret
.L11:
jne .L7
jmp f()
GCC10:
f1(float, float):
ucomiss %xmm1, %xmm0
jp .L4
comiss %xmm1, %xmm0
jne .L4
ret
.L4:
jmp f()
f2(float, float):
ucomiss %xmm1, %xmm0
jnp .L11
.L7:
ret
.L11:
jne .L7
jmp f()
