Rafael Espindola 46129b0934 Use StringRef::split instead of SplitString. 
llvm-svn: 87085
 2009-11-13 05:13:58 +00:00
Rafael Espindola ff2c72b858 Distinguish "a," from "a". The first one splits into "a" + "" and the second one into 
"a" + 0.

Anders Carlsson e828c36933 Add a special BuildVirtualCall that's going to be used for building calls to destructors. This is needed because when compiling: 
struct A {
	virtual ~A();
};

void f(A* a) {
	delete a;
}

A's deleting destructor should be called.

Anders Carlsson 78cfaa9e56 Fix two bugs with temporaries: 
1. For 

A f() {
	return A();
}

we were incorrectly calling the A destructor on the returned object.

2. For

void f(A);
void g() {
	A a;
	f(a);
}

we were incorrectly not calling the copy constructor.

Daniel Dunbar 636404a330 Add CompilerInstance, and starting moving clang-cc to it. 
- The design philosophy is in the CompilerInstance doxyment, if you don't agree
   with it now would be a good time to speak up.

Mike Stump fa81808a11 Refine construction vtables; they don't include bits that don't have 
virtual bases unless they are morally virtual.

Ted Kremenek aedb7434c8 Add clang-cc option "-analyzer-experimental-checks" to enable experimental path-sensitive checks. The idea is to separate "barely working" or "skunkworks" checks from ones that should always run. Later we need more fine-grain checker control.

David Greene 2f4c37425b Fix a bootstrap failure. 
Provide special isLoadFromStackSlotPostFE and isStoreToStackSlotPostFE
interfaces to explicitly request checking for post-frame ptr elimination
operands.  This uses a heuristic so it isn't reliable for correctness.

Douglas Gregor 9533e2803f We need the definition of NamedDecl in DeclContextInternals.h, since Clang is type-checking the template definition more thoroughly

David Greene 70fdd57dc1 Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a 
machine instruction loads or stores from/to a stack slot.  Unlike
isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be
something other than a pure load/store (e.g. it may be an arithmetic
operation with a memory operand).  This helps AsmPrinter determine when
to print a spill/reload comment.

This is only a hint since we may not be able to figure this out in all
cases.  As such, it should not be relied upon for correctness.

Implement for X86.  Return false by default for other architectures.

Bill Wendling e3ae25b3d8 If there's more than one function operand to a call instruction, be conservative 
and don't assume that the call doesn't throw. It would be nice if there were a
way to determine which is the callee and which is a parameter. In practice, the
architecture we care about normally only have one operand for a call instruction
(x86 and arm).
