When I put a breakpoint in expand_expr, I see that in the case of `++a[i]' `(reg:SI 72)' is being returned. When `a[i]++' is presented, then (queued:SI (mem:SI (reg:SI 70) 0) (nil) (nil) (parallel[ (set (mem:SI (reg:SI 70) 0) (plus:SI (mem:SI (reg:SI 70) 0) (const_int 1 [0x1]))) (clobber (reg:CC 17 flags)) ] ) (nil)) is returned. -S shows that no code is generated for `++a[i].' ./A class T { public static void main(String [] args) { int a[] = new int[1]; int i = 0; ++a[i]; System.out.println (a[i]); } }
