[LLVMdev] gcroot + `section not found for addresss ...' ???
Hi,
If I type
define i32 @main() gc "shadow-stack" {
entry:
%0 = alloca i8*
%1 = call i8* @malloc(i64 1)
store i8* %1, i8** %0
call void @llvm.gcroot(i8** %0, i8* null)
ret i32 0
}
declare i8* @malloc(i64)
declare void @llvm.gcroot(i8**, i8*) nounwind
in test.ll
and then do
> llc test.ll
> gcc test.s
I get the error
