; This testcase tests to see if adds and PHI's are handled in their full
|
|
; generality. This testcase comes from the following C code:
|
|
;
|
|
; void f() {
|
|
; int i;
|
|
; for (i = 1; i < 100; i++) {
|
|
; if (i)
|
|
; g();
|
|
; }
|
|
; }
|
|
;
|
|
; Note that this is a "feature" test, not a correctness test.
