Expected constant simplification not happening
Hi
the appended IR code does not optimize to my liking :)
this is the interesting part in x86_64, that got produced via clang -Os:
---
movq -16(%r12), %rax
movl -4(%rax), %ecx
andl $2298949, %ecx ## imm = 0x231445
cmpq $2298949, (%rax,%rcx) ## imm = 0x231445
leaq 8(%rax,%rcx), %rax
cmovneq %r15, %rax
movl $2298949, %esi ## imm = 0x231445
movq %r12, %rdi
movq %r14,
