At least DOM is being miscompiled or something weird is going on:
from loop.c's .vars:
- (T.6480 + regs->array)->set_in_loop = 0;
- p.6567 = p.6252;
- loop_depth.6251 = loop_depth.6570;
+ i = 0;
+
+<L467>:;
+ (regs->array + (struct loop_reg *)((unsigned int)(i + regno) * 16))->set_in_loop = 0;
+ i = i + 1;
+ if (i <= 0) goto <L467>; else goto <L1576>;
+
+<L1576>:;
+ p.6572 = p.6252;
+ loop_depth.6251 = loop_depth.6575;
