--- Comment #3 from Christophe Lyon <clyon at gcc dot gnu.org> ---
I do see different output with and without r266620 (attaching vcond_1.s.ok and
vcond_1.s.ko).

They are now checking different condition codes:
$ diff vcond_1.s.ok vcond_1.s.ko1014c1014
<       cmplt   p1.b, p0/z, z1.b, #5
---
>       cmple   p1.b, p0/z, z1.b, #4
1031c1031
<       cmplt   p1.h, p0/z, z1.h, #5
---
>       cmple   p1.h, p0/z, z1.h, #4
[...]

The testcase is compiled with -march=armv8.2-a+sve
