The legacy PM is deprecated, so update a bunch of lit tests running opt to use the new PM syntax when specifying the pipeline. In this patch focus has been put on test cases for ConstantMerge, ConstraintElimination, CorrelatedValuePropagation, GlobalDCE, GlobalOpt, SCCP, TailCallElim and PredicateInfo.

|
; the test was generated from the following C++ source:
|
|
;
|
|
; int zoo ( S p1 );
|
|
;
|
|
; int foo ( int count, S p1 ) {
|
|
; if ( count > 10 )
|
|
; return zoo(p1);
|
|
;
|
|
; // After TRE: temporarily variable created for passing byvalue parameter
|
|
; // p1 could be used when zoo(p1) is called.
|
|
; return foo(count+1, p1);
|
|
; }
|
|
|
|
; this test checks that value of ByValue operand AGG_TMP_I of call site foo()
|
|
; is copied into temporarily variable AGG_TMP_I1(byVal value holder) and
|
|
; later the value from AGG_TMP_I1 is copied into function argument P1 before
|
|
; new iteration started.
