* Simpler, more robust emulation of calls to variadic functions:xleroy2013-12-289-25/+26
| | | | | | | | | | | | | | - C function types and Cminor signatures annotated by calling conventions. esp. vararg / not vararg - Cshmgen: generate correct code for function call where there are more arguments than listed in the function prototype.
