I heard once that there was some long-term project of storing function declarations (without corresponding definitions) in a more memory-efficient memory representation. Moving default parameters within PARM_DECL seems a little backward in this respect. And if your memory is right, requiring to build PARM_DECLs just to store default arguments would be even worse. I understand this has to be done in a separate pass: I was just bringing up the issue so that, if possibile, we could find some place which does not conflict with that project. Giovanni Bajo
