constant.

 2009-01-24 23:29:36 +00:00
Eli Friedman 52cc016f21 PR3062: statement expressions should be illegal at file scope. I don't 
think this has any significant effects at the moment, but it could 
matter if we start constant-folding statement expressions like gcc does.

llvm-svn: 62943
 2009-01-24 23:09:00 +00:00
Eli Friedman 8549e5dcc8 Fix for PR2910: implement CodeGen for non-constant offsetof. 
Note that there are still other issues in this area; see PR3396.

llvm-svn: 62942
 2009-01-24 22:38:55 +00:00
Eli Friedman 2aa38fea35 Refactor sizeof handling to use constant folding logic for constant 
sizeof expressions.

llvm-svn: 62941
 2009-01-24 22:19:05 +00:00
Nate Begeman b09b0242ca Fix an indent and a typo. 
llvm-svn: 62940
 2009-01-24 22:12:48 +00:00
Chris Lattner 6806131c6b add initial support for the gcc "alignof(decl) is the alignment of the decl 
not the type" semantics.  This can definitely be improved, but is better than
what we had.

llvm-svn: 62939
 2009-01-24 21:53:27 +00:00
Dale Johannesen 2b3389a626 Revert previous change; even this mild and clearly 
more accurate change loses more than it gains on
benchmarks.

llvm-svn: 62938
 2009-01-24 21:49:34 +00:00
Sebastian Redl 887ce84b2b Undo accidental disabling of smart pointers.

 2009-01-24 21:29:22 +00:00
Fariborz Jahanian 4723fb70a9 Patch to build class meta-data for each implementation 
of class in objc2's nonfragile abi.

llvm-svn: 62935
 2009-01-24 21:21:53 +00:00
Sebastian Redl 9ed6efdd75 Add support for declaring pointers to members. 
Add serialization support for ReferenceType.

llvm-svn: 62934
 2009-01-24 21:16:55 +00:00
Chris Lattner 04964bbebe remove a bunch of alignment handling code out of CGExprScalar, since 
alignment must always be a constant.  Just let the constant folder 
do it.

llvm-svn: 62933
 2009-01-24 21:09:45 +00:00
Chris Lattner 24aeeab05c Improve handling of alignof. alignof(VLA) now works properly for example. 
llvm-svn: 62932
 2009-01-24 21:09:06 +00:00
Chris Lattner 7bf46469f3 fix some const-correctness issues. 
llvm-svn: 62931
 2009-01-24 21:08:33 +00:00
Chris Lattner 096d3ecb51 remove dead code. 
llvm-svn: 62930
 2009-01-24 20:24:49 +00:00
Fariborz Jahanian 9e3ad5220d This patch builds the meta-class object for each 
implemented class in objc2's nonfrigile abi.

llvm-svn: 62929
 2009-01-24 20:21:50 +00:00
Chris Lattner 8dff017695 Fix PR3386 by handling GCC's rules for alignof, which are substantially 
different than those for sizeof.  Reject alignof(bitfield) like gcc does.

llvm-svn: 62928
 2009-01-24 20:17:12 +00:00
Chris Lattner 619393762b fix a fixme, don't leak the expr on error. 
llvm-svn: 62927
 2009-01-24 19:49:13 +00:00
Chris Lattner b1355b1545 minor formatting changes, no functionality change. 
llvm-svn: 62926
 2009-01-24 19:46:37 +00:00
Torok Edwin 3cedd4dc64 add note about possible GEP improvement with fields of size 0. 
llvm-svn: 62925
 2009-01-24 19:30:25 +00:00
Daniel Dunbar 134a02586e Fix invalid evaluation of _Complex float (real & imaginary parts had 
mismatched semantics).
 - Enforce this in APValue.

llvm-svn: 62924
 2009-01-24 19:08:01 +00:00
Anders Carlsson a0b892113a Handle the 'e' constraint. Fixes PR3385 
llvm-svn: 62923
 2009-01-24 18:03:09 +00:00
Anders Carlsson b66a312f93 Ignore parens when determining if an expr is a string literal. Fixes PR3382.

Dan Gohman 73fd5a5651 Add a PR comment to this test. 
llvm-svn: 62921
 2009-01-24 17:32:54 +00:00
Torok Edwin f4395ea97a testcase for PR3381. 
Also it was an empty struct, not a void after all.

llvm-svn: 62920
 2009-01-24 17:16:04 +00:00
Dan Gohman 142ccc0e15 Add more documentation mentioning the limitations due to PR2660. 
llvm-svn: 62919
 2009-01-24 15:58:40 +00:00
Torok Edwin 73ff92272f void* is represented as pointer to empty struct {}. 
Thus we need to check whether the struct is empty before trying to index into
it. This fixes PR3381.

llvm-svn: 62918

Owen Anderson ee34b8f179 Some cleanups. No functional changes.

 2009-01-24 08:43:22 +00:00
Daniel Dunbar 3334a44501 Start filling in x86_64 ABI implementation. 
- No functionality change, moved behind -use-x86_64-abi option until
   it becomes non-experimental.

Dale Johannesen 899ecdbbba Improve the inlining cost function a bit. 
Little practical effect.

llvm-svn: 62908
 2009-01-24 01:27:33 +00:00
Chris Lattner 72cd68fe64 Make InstCombineStoreToCast handle aggregates more aggressively, 
handling the case in Transforms/InstCombine/cast-store-gep.ll, which
is a heavily reduced testcase from Clang on x86-64.

llvm-svn: 62904
 2009-01-24 01:00:13 +00:00
Ted Kremenek f08ac278ed More hacking on static analyzer diagnostics. When emitting summary diagnostics the code paths for diagnostics involving paths or single locations are now unified. This patch also constifies many arguments/methods that are touched by this logic, leading to a nice overall code cleanup. 
llvm-svn: 62903
 2009-01-24 00:55:43 +00:00
Mike Stump 82221d62a9 Perform optional clang building.

Evan Cheng 6d8970695b Refactor code. No functionality change. 
llvm-svn: 62893
 2009-01-23 23:27:33 +00:00
Devang Patel ccfacfff9a Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags. 
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.
