[LLVMdev] Troubling promotion of return value to Integer ...
...atively (and this may be quite a change) to identify sign
information, we can add new SimpleValueTypes (u1, u8, u16, ...) to
signify unsigned values in addition to (i1, i8, i16, ...) which are
signed values.
Then the front-end can define
unsigned char ug(...);
as: declare u8 @ug(...)
where DAG.isReturnValueSignExtended(...) returns false
and
signed char sg(...);
as: declare i8 @sg(...)
where DAG.isReturnValueSignExtended(...) returns true
In both cases DAG.getReturnValueRegisterSizeInBits(...) returns 32 (on a
32 bit architecture)
The caveat here is when we don't have a prototype for callee in which...
