Doesn't work on powerpc (gcc 13.4):
foo:
li 5,8192
li 4,0
b memset
foo2:
li 5,8193
li 4,0
b memset
But that's the reason why vdso Makefile has option -fno-builtin, that
option gives instead:
foo:
li 10,2048
li 9,0
addi 3,3,-1
mtctr 10
.L2:
stb 9,1(3)
stb 9,2(3)
stb 9,3(3)
stbu 9,4(3)
bdnz .L2
blr
foo2:
li 9,0
li 10,2048
stb 9,0(3)
mtctr 10
.L10:
