2012-12-12Rewrite calls to bitcast unprototyped functions when emitting a definition.John McCall
My variadics patch, r169588, changed these calls to typically be bitcasts rather than calls to a supposedly variadic function. This totally subverted a hack where we intentionally dropped excess arguments from such calls in order to appease the inliner and a "warning" from the optimizer. This patch extends the hack to also work with bitcasts, as well as teaching it to rewrite invokes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170034 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-21ANSI C requires that a call to an unprototyped function type succeedJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140241 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24Canonicalize parameter and return types before computing ABI info. EliminatesJohn McCall
a common source of oddities and, in theory, removes some redundant ABI computations. Also fixes a miscompile I introduced yesterday by refactoring some code and causing a slightly different code path to be taken that didn't perform *parameter* type canonicalization, just normal type canonicalization; this in turn caused a bit of ABI code to misfire because it was looking for 'double' or 'float' but received 'const float'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97030 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

to go back and clean up existing uses of the bitcasted function. This is not just an optimization: it is required for correctness to get always inline functions to work, see testcases in function-attributes.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70971 91177308-0d34-0410-b5e6-96231b3b80d8
