This unifies all the targets supported by an OS into a template.
It also cleans up the differences between the darwin targets.
Also __LP64__ wasn't needed for *BSD, since x86-64 target defines it anyway.

"semantic analysis" part. Use the "semantic analysis" part when
performing template instantiation on a DeclRefExpr, rather than an ad
hoc list of rules to construct DeclRefExprs from the instantiation.

A test case for this change will come in with a large commit, which
illustrates what I was actually trying to work on.

Mark the super region of the binding of block level expr in the Environment
as live.

unknown for it.

Mark the super region of a live region as live, if the live region is pointed
to by a live pointer variable.

These fixes xfail_regionstore_wine_crash.c.

This was caused by me confounding FP0 and ST(0).

DeclStmt would be dead before the DeclStmt.
For example:
int x = 0;
int y = x;
'x' would be dead before 'int y = x'.

Temporarily restore the scavenger implicit_def checking code. MachineOperand isUndef mark is not being put on implicit_def of physical registers (created for parameter passing, etc.).

llvm-svn: 74519

Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them.

The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.

This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.

Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

llvm-svn: 74506

It's not getASTContext() to avoid "getASTContext is ambiguous" compiler errors for subclasses of both Decl and DeclContext.

llvm-svn: 74505

Timings showed no significant difference before and after the commit.

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.
