Eli Friedman 2c81975bae Get rid of useless comment; if a file uses functions from a given header, 
it is obvious that it should be included.

Jakob Stoklund Olesen 7d05bce70c Use a faster algorithm for computing MBB live-in registers after register allocation.

Kevin Enderby 9377a52c12 Adding support for printing operands symbolically to llvm's public 'C' 
disassembler API.  Hooked this up to the ARM target so such tools as Darwin's
otool(1) can now print things like branch targets for example this:
  blx _puts
instead of this:
  blx #-36
And even print the expression encoded in the Mach-O relocation entried for
things like this:
  movt r0, :upper16:((_foo-_bar)+1234)

Jakob Stoklund Olesen f8beafe207 Don't add live ranges for sub-registers when clobbering a physical register. 
Both coalescing and register allocation already check aliases for interference,
so these extra segments are only slowing us down.

This speeds up both linear scan and the greedy register allocator.

Jakob Stoklund Olesen 4fbbe3689d Speed up LiveIntervalUnion::unify by handling end insertion specially. 
This particularly helps with the initial transfer of fixed intervals.

Jakob Stoklund Olesen 96d04c8e00 Don't shrink live ranges after dead code elimination unless it is going to help. 
In particular, don't repeatedly recompute the PIC base live range after rematerialization.

llvm-svn: 129265
 2011-04-11 02:03:26 +00:00
Anders Carlsson c1c9971cab When we know that a dynamic_cast always returns null, we can make 
CodeGenFunction::EmitDynamicCast always return null or throw a bad_cast 
exception.

Anders Carlsson 50ddb5cc0a Remove the CodeGenCXX/dyncast.cpp test; it isn't really super useful to match on huge chunks of LLVM output.

Anders Carlsson c602006638 As a first step towards fixing PR9641, add a CK_DynamicToNull cast kind which 
represents a dynamic cast where we know that the result is always null.

For example:

struct A {
  virtual ~A();
};
struct B final : A { };
struct C { };

bool f(B* b) {
  return dynamic_cast<C*>(b);
}

Chandler Carruth 016ef400c4 Enhance the diagnostic for literal float -> int conversions to suggest 
rewriting the literal when the value is integral. It is not uncommon to
see code written as:

  const int kBigNumber = 42e5;

Without any real awareness that this is no longer an ICE. The note helps
automate and ease the process of fixing code that violates the warning.
