This looks similar to PR79389, where two problems were exposed. In addition to
split-paths issue, perhaps something disturbed RTL if-conversion to generate
jump instead of cmova?
.L4:
movq (%r15,%rax,8), %rcx
vmovsd (%rcx,%rbx), %xmm0
vandpd %xmm3, %xmm0, %xmm0
vucomisd %xmm1, %xmm0
vmaxsd %xmm1, %xmm0, %xmm1
cmova %eax, %edx
addq $1, %rax
cmpl %eax, %r14d
jg .L4
