| 620 | |
| 621 Of course all this is different for the portable runtime model | |
| 622 HP wants everyone to use for ELF. Ugh. Here's a quick description | |
| 623 of how it's supposed to work. | |
| 624 | |
| 625 1) callee side remains unchanged. It expects integer args to be | |
| 626 in the integer registers, float args in the float registers and | |
| 627 unnamed args in integer registers. | |
| 628 | |
| 629 2) caller side now depends on if the function being called has | |
| 630 a prototype in scope (rather than if it's being called indirectly). | |
| 631 | |
| 632 2a) If there is a prototype in scope, then arguments are passed | |
| 633 according to their type (ints in integer registers, floats in float | |
| 634 registers, unnamed args in integer registers. | |
| 635 | |
| 636 2b) If there is no prototype in scope, then floating point arguments | |
| 637 are passed in both integer and float registers. egad. | |
| 638 | |
| 639 FYI: The portable parameter passing conventions are almost exactly like | |
| 640 the standard parameter passing conventions on the RS6000. That's why | |
| 641 you'll see lots of similar code in rs6000.h. */ | |
