--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> ---
That's really weird as I see the vxrm assignment to round down at the very
beginning of the function -- which is exactly what we want as some designs
flush their instruction pipelines when they encounter the vxrm assignment.
main:
csrwi vxrm,2
addi sp,sp,-32
[ ... ]
.L2:
vsetvli a5,a3,e16,mf4,ta,ma
vle16.v v1,0(a2)
slli a1,a5,1
subw a3,a3,a5
add a2,a2,a1
vasub.vx v1,v1,zero
vse16.v v1,0(a4)
add a4,a4,a1
bgt a3,zero,.L2
addi s2,s2,20
la s0,a
la s1,b
[ ... ]
And running on the BPI I get:
0 2 5 7 10 12 15 17 20 22
