Matthijs Kooijman be4fc9b9fb Add a testcase showing that scalarrepl supports first class structs. 
I originally made this script to show that scalarrepl didn't support them, but
it turned out it does. Better to still add the testcase then.

Chris Lattner 037379d767 Fix rdar://6252231 - cannot call vsnprintf with va_list on x86_64, 
by decaying __builtin_va_list's type when forming builtins.  On
x86-64 (and other targets) __builtin_va_list is a typedef for
an array.

Chris Lattner ff2c187e59 Replace a comparison with a static list of builtins that was wrong (it 
wasn't covering checking builtins like __builtin___vsnprintf_chk) with
a check that won't get out of date.

Dan Gohman 843fe14fab Move the code that handles DAGISel error conditions into 
helper functions instead of duplicating it inline each time
it is needed. This eliminates a few hundred or so copies
of this code in each target.

Daniel Dunbar 7f08678f7d (Update LLVM) Clean up obj-c exception generation to be a bit more 
readable and to generate more readable IR.

Daniel Dunbar c7486c8636 Add IRBuilder::{CreateIsNull, CreateIsNonNull} helper methods. 
- I'm open to the idea that these could have better names. I think
   these read better than CreateEQNull and CreateNENull.

Daniel Dunbar 86919f45cc Bug fix, codegen @catch(id<X> ...) acceptably. 
- This should be rejected by sema (IMHO) but that needs some
   investigation.

Ted Kremenek 21c24f1785 Revert 56735. The old bug categories were more informative. 
llvm-svn: 56755
 2008-09-27 22:02:42 +00:00
Daniel Dunbar 523208fb4a Simplify generate code for exceptions: 
- There is no need to branch on the rethrow variable to determine if
   we need to call objc_exception_try_exit. We know whether an
   exception was thrown, so just branch to a different target if we
   want to skip the try_exit. 

   This is a slight semantic departure from gcc, but only for throwing
   nil, which is undefined (and for which gcc emits broken code).

 - Also fixes a bug in current code which was calling try_exit too
   many times when an exception was uncaught (but there were some
   handlers).

Fix bug introduced in prev. commit, the type of the @catch parameter
was uninitialized.

Daniel Dunbar 274ff37583 Simplify code to emit the unified return block and move it to the end 
of the function.

llvm-svn: 56752
 2008-09-27 07:15:59 +00:00
Daniel Dunbar b22ff59750 Bug fix, make sure to initialize exception object (to rethrow) even 
when there are no @catch blocks.

Also, eliminated unneeded alloca for the rethrow object.

Also, avoid generating code to rethrow exception if the exception will
trivially always be caught.

Daniel Dunbar da04d7f4ec Easy fix for nasty bug, exception data buffer had wrong type == wrong 
(smaller) size == garbage on stack == heisenbugs.
