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.

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

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 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.

Ted Kremenek 8bafa2cf9f Internally store the body of a BlockExpr using a Stmt* instead of a CompoundStmt*, and use the getBody() method to do the appropriate checking. This both removes the type-punning warnings in Expr.cpp and also makes BlockExpr have more consistency checks against modifications to its body (via StmtIterator).

Devang Patel 597e70876e Now Attributes are divided in three groups 
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

Chris Lattner c88a23e8d7 Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo 
to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

Chris Lattner 6bea488c79 testcase for my previous patch. 
llvm-svn: 56670
 2008-09-26 18:07:51 +00:00
Chris Lattner e744d32b72 emulate a bit of GCC path lookup weirdness: if a system 
directory is shadowed by a user directory in the lookup
path, ignore the user directory not the system one.  Not
doing this can affect file lookup and the "is a system
header" bit on locations.  For example:
  clang -v -I/usr/include inc.c -E | & grep /usr/inc
now prints:

# 1 "/usr/include/i386/_types.h" 1 3 4
# 37 "/usr/include/i386/_types.h" 3 4
# 70 "/usr/include/i386/_types.h" 3 4

instead of:

# 1 "/usr/include/i386/_types.h" 1
# 37 "/usr/include/i386/_types.h"
# 70 "/usr/include/i386/_types.h"

This is part of rdar://6243860.
