* Whether an argument is required (in contrast with being anJohn McCall2012-02-171-16/+27
| | | | | | | | | | | | | | | | | | | | | optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. llvm-svn: 150788

* Add field PaddingType to ABIArgInfo which specifies the type of padding thatAkira Hatanaka2012-01-071-10/+24

* ANSI C requires that a call to an unprototyped function type succeedJohn McCall2011-09-211-0/+17
| | | | | | | | | | | | | | | | | if the definition has a non-variadic prototype with compatible parameters. Therefore, the default rule for such calls must be to use a non-variadic convention. Achieve this by casting the callee to the function type with which it is required to be compatible, unless the target specifically opts out and insists that unprototyped calls should use the variadic rules. The only case of that I'm aware of is the x86-64 convention, which passes arguments the same way in both cases but also sets a small amount of extra information; here we seek to maintain compatibility with GCC, which does set this when calling an unprototyped function. Addresses PR10810 and PR10713. llvm-svn: 140241
