Anders Carlsson 82aea737a7 Move code generation of C++ temporaries into a new file. 
llvm-svn: 72792
 2009-06-03 18:40:21 +00:00
Eli Friedman cb9d07caeb Add support for __builtin_unwind_init. 
Also, committing an #if 0'ed __builtin_setjmp and __builtin_longjmp 
implementation I've had sitting in my tree for a while.  I haven't 
enabled it because the LLVM backend support isn't complete yet.

Eli Friedman f6bd15038c If we recognize alloca, treat it as a builtin. This fixes uses of 
alloca without declaring it.

K&R-style definition.

llvm-svn: 72591
 2009-05-29 21:03:38 +00:00
Douglas Gregor 7de5966d76 Create a new PrintingPolicy class, which we pass down through the AST 
printing logic to help customize the output. For now, we use this
rather than a special flag to suppress the "struct" when printing
"struct X" and to print the Boolean type as "bool" in C++ but "_Bool"
in C.

 2009-05-29 20:38:28 +00:00
Eli Friedman 9444638e4e Re-add a slightly more general version of the check from r72578; it is 
actually necessary in some obscure cases.

llvm-svn: 72585
 2009-05-29 19:23:46 +00:00
Mike Stump a678874975 Oops, the testcase I was thinking of is supposed to error out. I 
tried other things that might trip, but they all worked.

llvm-svn: 72578
 2009-05-29 17:06:45 +00:00
Mike Stump df0fe27b66 Fixup the rest of the trivial cases of the codegen of volatile. If 
any body can spot codegen bugs with volatile, or knows of any in the
bug database, let me know.

llvm-svn: 72572
 2009-05-29 15:46:01 +00:00
Eli Friedman 2a69547f38 PR4281: Fix bogus CodeGen assertion. The issue is that 
getUnqualifiedType() doesn't strip off all qualifiers for non-canonical 
types.

llvm-svn: 72552
 2009-05-28 23:04:00 +00:00
Mike Stump 01c2d0a17c Not setting all the fields is confusing... 
llvm-svn: 72506
 2009-05-28 00:16:27 +00:00

llvm-svn: 72504
 2009-05-27 23:45:33 +00:00
Fariborz Jahanian 7c1baf46d6 No write-barrier for initializations.

llvm-svn: 72449
 2009-05-27 01:45:47 +00:00
Mike Stump 3e97f3b35d Fix typo. I also fixed the hard to read case differences, so that no 
one else is tempted to copy the style, incorrectly.

llvm-svn: 72448
 2009-05-27 01:42:21 +00:00
Anders Carlsson 3a9463bfda Rename an EmitCallExpr function to EmitCall to make it clear that it doesn't emit an expr. 
llvm-svn: 72446
 2009-05-27 01:22:39 +00:00
Mike Stump ec3cbfe8c6 Fixup codegen for volatile structs in the trivial cases (a a=a and a=a=a). 
llvm-svn: 72439
 2009-05-26 22:03:21 +00:00
Daniel Dunbar bee70bd1e7 Use .data() instead of &...[0]. 
- Just SmallVectors this time.

llvm-svn: 72432
 2009-05-26 19:40:20 +00:00
Mike Stump 25306cacc6 Esnure that if we have a volatile structure as the destination, that 
we actually have a destination.

llvm-svn: 72429
 2009-05-26 18:57:45 +00:00
Daniel Dunbar 1518b64ddc When trying to pass an argument on the stack, assume LLVM will do the right 
thing for non-aggregate types.
 - Otherwise we unnecessarily pin values to the stack and currently end up
   triggering a backend bug in one case.

 - This loose cooperation with LLVM to implement the ABI is pretty ugly.

 - <rdar://problem/6918722> [irgen] clang miscompile of many pointer varargs on
   x86-64

llvm-svn: 72419
 2009-05-26 16:37:37 +00:00
Eli Friedman 895771aa4b Handle the edge case of a weak function with incomplete type correctly. 
Found by code inspection; I haven't seen this in real-world code.

llvm-svn: 72408

Mike Stump b9f2518626 Propagate volatile for implicit property refernces. 
llvm-svn: 72353
 2009-05-23 23:52:31 +00:00
Mike Stump 9afc476d4a Propagate volatile around for property references. 
llvm-svn: 72352
 2009-05-23 23:48:13 +00:00
Mike Stump 5e9e61b8d2 Track volatile aggregate copies better. I'm hoping someone else will decide 
how to get the backend to know that the operation is volatile.
