Bug ID: 16878
Summary: Itanium Mangling wrong with unsigned integer literals
passed to integer parameters
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
consider:
template <int I> struct A {
};
template <int I, int J> A<I+J> f(A<I>, A<J>) {
A<I+J> a;
return a;
}
A<0x80000001> (*g)(A<0x80000000>, A<1>) = &f;
we mangle it like:
_Z1fILin_2D_2147483648ELi1EE1AIXplT_T0_EES0_IXT_EES0_IXT0_EE
demangles like:
A<(-_2D_2147483648)+(1)> f<-_2D_2147483648, 1>(A<-_2D_2147483648>, A<1>)
I think we should mangle it like:
_Z1fILin2147483648ELi1EE1AIXplT_T0_EES0_IXT_EES0_IXT0_EE
demangles like:
A<(-2147483648)+(1)> f<-2147483648, 1>(A<-2147483648>, A<1>)
