Jordy Rose 134a236a14 Add a new path-sensitive checker for functions in <string.h>, for both null-terminated strings and memory blocks. Currently only checks memcpy(), memmove(), and bcopy(), but this is intended to be expanded soon.

Jim Ingham 279a6c2669 Hide the logic for command resolution for commands, aliases & user commands behind a single 
interface so everybody does it the same way.  Add an "exact" lookup for internal uses.

Fix up a few little cases where we weren't reporting command lookup errors correctly.

Added "b" as an alias for "breakpoint" so it doesn't collide with "bt".

Tom Care 3ff08a8e76 Added a path-sensitive idempotent operation checker (-analyzer-idempotent-operation). Finds idempotent and/or tautological operations in a path sensitive context, flagging operations that have no effect or a predictable effect. 
Example:
{
int a = 1;
int b = 5;
int c = b / a; // a is 1 on all paths
}

- New IdempotentOperationChecker class
- Moved recursive Stmt functions in r107675 to IdempotentOperationChecker
- Minor refactoring of SVal to allow checking for any integer
- Added command line option for check
- Added basic test cases

Jakob Stoklund Olesen a64c0a3d22 Be more forgiving when calculating alias interference for physreg coalescing. 
It is OK for an alias live range to overlap if there is a copy to or from the
physical register. CoalescerPair can work out if the copy is coalescable
independently of the alias.

This means that we can join with the actual destination interval instead of
using the getOrigDstReg() hack. It is no longer necessary to merge clobber
ranges into subregisters.

Gabor Greif 33134fa75f second round of low-level interface squeeze-out: 
making all of CallInst's low-level operand accessors
private

If you get compile errors I strongly urge you to
update your code.


I tried to write the necessary clues into the
header where the compiler may point to, but no
guarantees. It works for my GCC.

You have several options to update your code:

- you can use the v2.8 ArgOperand accessors
- you can go via a temporary CallSite
- you can upcast to, say, User and call its
  low-level accessors if your code is definitely
  operand-order agnostic.

If you run into serious problems, please
comment in below thread (and back out this
revision only if absolutely necessary):
