John McCall a464ff9d15 Switch some random local-decl cleanups over to using lazy cleanups. Turn on 
the block-release unwind cleanup:  we're never going to test it if we don't turn
it on.

 2010-07-21 06:13:08 +00:00
John McCall 906da4bb52 Switch finally cleanups over to being lazy cleanups. We get basically nothing 
from the laziness features here except better block ordering, but it removes yet
another CleanupBlock use.

Douglas Gregor 05fc5be32f Implement zero-initialization for array new when there is an 
initializer of (). Make sure to use a simple memset() when we can, or
fall back to generating a loop when a simple memset will not
suffice. Fixes <rdar://problem/8212208>, a regression due to my work
in r107857.

 2010-07-21 01:10:17 +00:00
John McCall 1e67040fb7 Convert the end-catch call for finally blocks to a lazy cleanup. This kills off 
the last of the shared-code cleanups.

John McCall c20acd31f7 Convert the ObjC @synchronized cleanups to laziness. This is not actually 
a big deal, except that I want to eliminate the shared-code EH cleanups
in preparation for a significant algorithmic fix.

Chris Lattner f2f3870189 Follow the implementation approach suggested by PR6687, 
which generates more efficient and more obviously conformant
code.  We now test for overflow of the multiply then force
the result to -1 if so.  On X86, this generates nice code
like this:

__Z4testl:                              ## @_Z4testl
## BB#0:                                ## %entry
	subl	$12, %esp
	movl	$4, %eax
	mull	16(%esp)
	testl	%edx, %edx
	movl	$-1, %ecx
	cmovel	%eax, %ecx
	movl	%ecx, (%esp)
	call	__Znam
	addl	$12, %esp
	ret

Fariborz Jahanian 217af240b5 Adopt objc_assign_threadlocal() for __thread variables of GC types. 
Implements radar 8203301.

Devang Patel 6c01820900 Print template argument names for template class.

 2010-07-20 20:24:18 +00:00
Chris Lattner 26008e07de implement rdar://5739832 - operator new should check for overflow in multiply, 
causing clang to compile this code into something that correctly throws a
length error, fixing a potential integer overflow security attack:

void *test(long N) {
  return new int[N];
}

int main() {
  test(1L << 62);
}

We do this even when exceptions are disabled, because it is better for the
code to abort than for the attack to succeed.

This is heavily based on a patch that Fariborz wrote.

Douglas Gregor af82e3510b Introduce a new lexer function to compute the "preamble" of a file, 
which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.
