; Test: ExternalConstant
;
; Description:
; This regression test helps check whether the instruction combining
; optimization pass correctly handles global variables which are marked
; as external and constant.
;
; If a problem occurs, we should die on an assert(). Otherwise, we
; should pass through the optimizer without failure.
;
; Extra code:
; RUN: as < %s | opt -instcombine
;
target endian = little
target pointersize = 32
%silly = external constant int ; <int*> [#uses=1]
implementation ; Functions:
declare void %bzero(sbyte*, uint)
declare void %bcopy(sbyte*, sbyte*, uint)
declare int %bcmp(sbyte*, sbyte*, uint)
declare int %fputs(sbyte*, sbyte*)
declare int %fputs_unlocked(sbyte*, sbyte*)
int %function(int %a.1) {
entry: ; No predecessors!
%a.0 = alloca int ; <int*> [#uses=2]
%result = alloca int ; <int*> [#uses=2]
store int %a.1, int* %a.0
%tmp.0 = load int* %a.0 ; <int> [#uses=1]
%tmp.1 = load int* %silly ; <int> [#uses=1]
%tmp.2 = add int %tmp.0, %tmp.1 ; <int> [#uses=1]
