Duncan Sands 536c399579 Turn off the new FastCC for the moment. It causes
a slew of Ada testsuite failures on x86-32 linux.
Seems to be related to the use of float.

Daniel Dunbar 573884eaf7 Implement ABIArgType::Coerce support.
- 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).

Daniel Dunbar b8b4759462 Add CodeGenTypes::GetFunctionType overload for getting the effective
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.

Daniel Dunbar 7a95ca3197 Move FunctionType conversion into CGCall.cpp:
- 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.

Argyrios Kyrtzidis 07052350f0 Implement CodeGen support for the 'CXXConditionDeclExpr' expression node, which represents a 'condition' declaration, e.g: "if (int x=0) {...}".

Daniel Dunbar c68897d2c3 Tweak CGCall functions again:
- 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
2008-09-10 00:41:16 +00:00
Daniel Dunbar 76c8eb75b1 Tweak CGCall functions:
- Move actual param attr list creation to
   CodeGenFunction::ConstructParamAttrList.
 - Make ReturnTypeUsesSret static.

2008-09-10 00:24:59 +00:00
Bill Wendling 648930b9ba Implement "visitPow". This is mainly used to see if we have a pow() call of this
form:

          powf(10.0f, x);

If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

Daniel Dunbar 81cf67fa0b Add CodeGenFunction::ReturnTypeUsesSret
- Hook so NeXT runtime doesn't depend on ABI.

Argyrios Kyrtzidis aa479138ea Add new 'CXXConditionDeclExpr' expression node used for a 'condition' declaration, e.g: "if (int x=0) {...}".
It is a subclass of DeclRefExpr and the main difference is that CXXConditionDeclExpr owns the declaration that it references.

Dan Gohman b4c0295b8e Change -fast-isel-no-abort to -fast-isel-abort, which now defaults
to being off by default. Also, add assertion checks to check that
the various fast-isel-related command-line options are only used
when -fast-isel itself is enabled.

function.

Dale Johannesen abb1e7770b Move the uglier parts of deciding not to emit a
UsedDirective for some symbols in llvm.used into
Darwin-specific code.  I've decided LessPrivateGlobal
is potentially a useful abstraction and left it in
the target-independent area, with improved comment.

Dan Gohman 91491b51e2 Add a new option, -fast-isel-verbose, that can be used with
-fast-isel-no-abort to get a dump of all unhandled instructions,
without an abort.

Argyrios Kyrtzidis 2bdac73591 Make IdentifierResolver::isDeclInScope regard declarations of a parent 'control' scope as part of the current scope.
The 'control' scope is the 'condition' scope of if/switch/while statements and the scope that contains the for-init-statement and 'condition' of a for statement.

e.g:
if (int x = 0 /*'control' scope*/) {
  // x will be regarded as part of this substatement scope.
} else {
  // and as part of this substatement scope too.
}
