Zhongxing Xu f0c133fe88 This patch adds support for tmpfile in StreamChecker. Patch by Lei Zhang.

 2010-07-22 14:01:01 +00:00
Zhongxing Xu adf644d05e Make a bunch of new data structures for the new analysis 
engine of the new translation unit. State marshal is there but no real
work is done. End nodes are passed back.

Chandler Carruth 3c31aa3a44 Fix PR7673 by allowing an empty clobbers section in an ASM statement. 
llvm-svn: 109087
 2010-07-22 07:11:21 +00:00
Chandler Carruth 96f2e9e418 Add alternate names for x86 SIMD intrinsics. These aren't as common, but show 
up enough to be worth supporting properly. Fixes PR7674.

Daniel Dunbar 6d48476446 Driver/Darwin: Set -force_cpusubtype_ALL only by default on x86. 
llvm-svn: 109074
 2010-07-22 01:47:22 +00:00
Daniel Dunbar 43d74a3b02 build: Make sure arm_neon.h gets installed. 
llvm-svn: 109073
 2010-07-22 01:19:36 +00:00
Daniel Dunbar a66a4d10ae Driver/Darwin: Always allow blocks on Darwin, so that users can conditionally 
use blocks even when targetting older systems (using runtime checks and weak
linking).

Devang Patel 222f4be834 ObjCId is special "struct objc_object". Make this explicit in debug info. 
This is tested by objc-rbreak.exp in gdb testsuite.

Sebastian Redl 4e6c567653 Allow loading macros from any file in the chain. WIP 
llvm-svn: 109048
 2010-07-21 22:31:37 +00:00
Ted Kremenek 1ddd6d2b6b Upgrade "'X' is unavailable" from a warning to an error. This matches GCC's behavior. Note that 
GCC emits a warning instead of an error when using an unavailable Objective-C protocol, so now
Clang's behavior is more strict in this case, but more consistent.  We will need to see how much
this fires on real code and determine whether this case should be downgraded to a warning.

Fixes <rdar://problem/8213093>.

 2010-07-21 20:43:11 +00:00
Sebastian Redl fa0614458a Promote some macro-related stuff to per-file data. Fix a cache-inefficient nested loop by inverting the nesting. Store the size of each file in the chain; will need this later for statement offsets.

John McCall cda666ccd8 Rename LazyCleanup -> Cleanup. No functionality change for these last three 
commits.

llvm-svn: 108993
 2010-07-21 06:20:50 +00:00
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.

llvm-svn: 108992
 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.

John McCall 1d9875654f Convert the EH cleanups for base and member destructors in a constructor into 
lazy cleanups.

 2010-07-21 01:23:41 +00:00
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.

llvm-svn: 108977
 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.

Sebastian Redl c713b9665b Allow loading identifiers from any file in the chain. WIP 
llvm-svn: 108974
 2010-07-21 00:46:22 +00:00
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.

llvm-svn: 108973
 2010-07-21 00:41:47 +00:00
John McCall 8f51041184 Add a little helper method which will be useful soon.

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
