Bug ID: 34052
Summary: [NewGVN/PredicateInfo] Assertion `isa<X>(Val) &&
"cast<Ty>() argument of incompatible type!"' failed.
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: dav...@freebsd.org
CC: dber...@dberlin.org, jo...@netbsd.org,
llvm-bugs@lists.llvm.org
Joerg ran a full package run on NetBSD (with NewGVN) and that resulted in a
series of crashes. This one is the first, in the objective-c runtime.
I reduced it to the following:
$ ./opt -newgvn tinky.ll
opt: ../include/llvm/Support/Casting.h:255: typename llvm::cast_retty<X,
Y*>::ret_type llvm::cast(Y*) [with X = llvm::Function; Y = llvm::Constant;
typename llvm::cast_retty<X, Y*>::ret_type = llvm::Function*]: Assertion
`isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
$ cat tinky.ll
%0 = type opaque
%2 = type opaque
define void @patatino() {
entry:
%call10 = call %0* bitcast (i8* (i8*, ...)* @objc_msgSend to %0* (i8*)*)(i8*
null)
%cmp11 = icmp eq %0* %call10, null
br i1 %cmp11, label %if.end14, label %if.end14.thread
if.end14.thread:
%tmp = bitcast %0* %call10 to i8*
ret void
if.end14:
ret void
}
declare i8* @objc_msgSend(i8*, ...)
declare %2* @llvm.ssa.copy.p0s_s(%2* returned)
