2012-01-07Add field PaddingType to ABIArgInfo which specifies the type of padding thatAkira Hatanaka
is inserted before the real argument. Padding is needed to ensure the backend reads from or writes to the correct argument slots when the original alignment of a byval structure is unavailable due to flattening. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147699 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10Constant expression evaluation refactoring:Richard Smith
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions, and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert behaviour. - Factor out evaluation of bitfield bit widths. - Fix a few places which would evaluate an expression twice: once to determine whether it is a constant expression, then again to get the value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141561 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

2011-08-03Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.Bob Wilson
A homogeneous aggregate is an aggregate data structure where after flattening any nesting there are 1 to 4 elements of the same base type that is either a float, double, or Neon vector. All Neon vectors of the same size, either 64 or 128 bits, are treated as equivalent for this purpose. When using the AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by expanding them into a sequence of their base types. This requires extending the existing support for expanded arguments to handle not only structs, but also constant arrays and complex types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136767 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-01Revert "Re-enable byval for ARM in clang. rdar://problem/7662569"Bob Wilson
This reverts commit 67d097e1232b7d66f58989c16a45b8a11721f76e. We found a miscompile with ARM byval, which is still being investigated. In the meantime, this works around the problem by disabling ARM byval.
