* LLVM IR: Generate new-style byval-with-Type from ClangTim Northover2019-06-051-2/+2
| | | | | | | | | | | LLVM IR recently added a Type parameter to the byval Attribute, so that when pointers become opaque and no longer have an element type the information will still be present in IR. For now the Type parameter is optional (which is why Clang didn't need this change at the time), but it will become mandatory soon. llvm-svn: 362652

* Allowing individual targets to determine whether a given calling convention ↵Aaron Ballman2012-10-021-1/+1

* ANSI C requires that a call to an unprototyped function type succeedJohn McCall2011-09-211-1/+1
| | | | | | | | | | | | | | | | | 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

* Standardize the parsing of function type attributes in a way thatJohn McCall2010-02-051-4/+4
| | | | | | | | | | | | follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). llvm-svn: 95436

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-2/+2
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
* Eliminate &&s in tests.Daniel Dunbar2009-11-081-1/+1

| | | | | | | | - This is just to normalize, these will go away soon hopefully. Added all the missing '&&'s that have crept in. :) llvm-svn: 77062
