we get these declarations ``` ; opt level 0 declare x86_intrcc void @page_fault_handler(ptr byval([8 x i8]) align 8, i64) unnamed_addr #1 ; opt level > 0 declare x86_intrcc void @page_fault_handler(ptr noalias nocapture noundef byval([8 x i8]) align 8 dereferenceable(8), i64 noundef) unnamed_addr #1 ``` The space after `i64` in the original regex made the regex not match for opt level 0. Removing the space fixes the issue. ``` declare x86_intrcc void @page_fault_handler(ptr {{.*}}, i64 {{.*}}){{.*}}#[[ATTRS:[0-9]+]] ```
