eightbyte boundaries.
- Getting harder to test now that we handle cases gcc & llvm-gcc get
wrong ( { _Complex char; _Complex int; } is a good example). :)

- This is my best initial guess at what the "spec" means, although it is not
particularly clear on a number of points. Will refine through testing.
llvm-svn: 63292
filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.
llvm-svn: 61994
- Update comment to reflect fact that StructRet is now supported for
any type (modulo LLVM support).
- No functionality change, no scalar types currently use this
feature.
llvm-svn: 61192
- Currently still lives in CGCall.cpp but is intended to be the
target specific place for hooking ABI information.
- Select ABIInfo to use based on Target's prefix and pointer width.
llvm-svn: 57445
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn
Return attributes use 0 as the index.
Function attributes use ~0U as the index.

This sets the stage
- to implement function notes as function attributes and
- to distinguish between function attributes and return value attributes.
llvm-svn: 56623
- Enables use of ABIArgInfo::Expand when needed. This greatly
improves our x86 ABI compatibility.
- As the infrastructure for target specific ABI handling isn't built
yet, this change means ABI compatibility on other platforms is once
again broken in a different way than before.
- Upcoming: Figure out how to refactor ABI handling into
targets. More documentation.

Ensure that ABIArgInfo::Default implementation for aggregrate types
is sensible (StructRet on return and ByVal on arguments).
No functionality change.

value).
- Added ABIArgInfo::ByVal (mostly supported) and ABIArgInfo::Expand
(asserted out).
- Added classifyArgumentType which currently just uses
ABIArgInfo::Default or ByVal. This nearly matches old behavior, but
we now set ByVal in a few situations we may have left it off before
(on complex, for example).
llvm-svn: 56086
no method declaration was found.
- This was allowing arrays to pass "by value" among other things.
Add assert in CodeGen that arguments cannot have array type.
llvm-svn: 56080
- As a test, enable basic usage for some common x86-32 cases. This
increases our x86-32 compliance (on other targets our compliance
will just be broken in a different way).
llvm-svn: 56051
type of a call.
Change NeXT runtime to use this instead of trying to bitcasting
internally (which doesn't respect the ABI).
Fix subtle bug, use of ConvertTypeRecursive instead of ConvertType is
bad inside GetFunctionType.
llvm-svn: 56050
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo.
- Updated Obj-C runtimes to use this instead of rolling the
llvm::FunctionType by hand.
- Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}.
Add ABIArgInfo class to encapsulate ABI decision of how to lower types
to LLVM.
- Will move to target sometime soon.
llvm-svn: 56047
- Realized these functions will eventually need access to more data,
moved to CodeGenModule. Eventually they should probably live
together in some other helper class.
llvm-svn: 56039
- Add CodeGenFunction::EmitAnyExprToTemp
o Like EmitAnyExpr, but emits aggregates to a temporary location if
none is available. Seems like this should be simpler (even aside
from using first class aggregates).
- Killed CodeGenFunction::EmitCallArg (just append the pair)
- Conversion of RValues to actual call arguments is now isolated in
CodeGenFunction::EmitCall.
llvm-svn: 55970
- Add CGCall.h for dealing with ABI issues related to calls.
- Add CGFunctionInfo and CGCallInfo for capturing ABI relevant
information about functions and calls.
- Isolate LLVM parameter attribute handling inside CGCall.cpp
