instructions (with patterns) that load memory marked, for example.

Add a isImmutable bit to StackObject. Fixed stack objects are immutable (in the function) unless specified otherwise.

removing them, fitting the file into 80 columns. :)

Put return type of synthesize method on same line as method declaration, space after method declaration header.

MachineRegisterInfo.  Once all clients are switched over, the former will be going away.

llvm-svn: 45805

The first only returns definitions of a register, the second only
returns uses, the third returns both.

llvm-svn: 45799

Do not use the stack pointer directly, issue a copyfromreg instead. Otherwise we can end up with something like ADD32ri %esp, x which two-address pass won't like.

than hardware supported type will be scalarized, so we
can infer their alignment from that info.

We now codegen pr1845 into:

_boolVectorSelect:
	lbz r2, 0(r3)
	stb r2, -16(r1)
	blr

Add a FIXME to commit r45784. Thanks mrs!

llvm-svn: 45790

Fix Sema::ActOnDeclarator() to call MergeFunctionDecl for function decls that aren't in scope. Since C functions are in a flat namespace, we need to give them special treatment (when compared with variables and typedefs).

so that nodes can be marked as representing an infeasible program point. This
flag lets the path-sensitive solver know that no successors should be generated
for such nodes.

BExpr*** and ***BExpr respectively. These edges represent program locations
between the entrance/exit of a block and Block-level Expressions.

Also added ***SExpr and SExpr*** ProgramEdges to represent the locations in the
program between the evaluation of subexpressions and block-level expressions.

llvm-svn: 45786

code restructuring.  (new files will be introduced shortly)

llvm-svn: 45785

Fix ASTContext::typesAreCompatible to allow for int/enum compatibility (C99 6.7.2.2p4).
Fix Sema::MergeFunctionDecl to allow for function type compatibility (by using the predicate on ASTContext). Function types don't have to be identical to be compatible...

llvm-svn: 45784

Clean up StrongPHIElimination a bit, and add some more comments to the internal structures.  There's
still more work to do on this front.
