Alexis Hunt 656bb314d9 Reapplying patch to change StmtNodes.def to StmtNodes.td, this time 
with no whitespace. This will allow statements to be referred to in
attribute TableGen files.

Alexis Hunt a8136cc408 Revert r103072; I accidentally ended up deleting a bunch of trailing 
whitespace which makes this patch unreadable. Will recommit without the
whitespace.

Douglas Gregor 96c79498fb Improve the AST representation of Objective-C @try/@catch/@finally 
statements. Instead of the @try having a single @catch, where all of
the @catch's were chained (using an O(n^2) algorithm nonetheless),
@try just holds an array of its @catch blocks. The resulting AST is
slightly more compact (not important) and better represents the actual
language semantics (good).

Chris Lattner 1a8f394a1f david conrad points out that {|} in inline assembly on arm are not asm 
variants.  This fixes neon inline asm which my patch for PR6780 broke.

Douglas Gregor d7d70e4788 Remove the AST statistics tracking I added yesterday; it didn't pan out.

 2010-03-31 18:21:31 +00:00
Douglas Gregor ad2c6988a2 Introduce new AST statistics that keep track of the number of isa (or 
dyn_cast) invocations for C++ and Objective-C types, declarations,
expressions, and statements. The statistics will be printed when
-print-stats is provided to Clang -cc1, with results such as:

277073 clang - Number of checks for C++ declaration nodes
 13311 clang - Number of checks for C++ expression nodes
    18 clang - Number of checks for C++ statement nodes
174182 clang - Number of checks for C++ type nodes
 92300 clang - Number of checks for Objective-C declaration nodes
  9800 clang - Number of checks for Objective-C expression nodes
     7 clang - Number of checks for Objective-C statement nodes
 65733 clang - Number of checks for Objective-C type nodes

The statistics are only gathered when NDEBUG is not defined, since
they introduce potentially-expensive operations into very low-level
routines (isa).

Sam Weinig a16b0dd1ae Implement Doug's suggestion. Eliminate the Stmts pointer from CXXTryStmt and instead allocate the statements after the object.

 2009-12-24 00:39:05 +00:00
Ted Kremenek b27a6d24a6 Add StmtIterator support for iterating over both the condition 
variable initializer and the other expressions in an IfStmt.

This change required adding a 'DoDestroy()' method for IfStmt that did
not include destroying the initializer (since that is owned by the
VarDecl).

 2009-12-23 23:38:34 +00:00
Ted Kremenek 00d19ee130 Add 'DeclStmt::DoDestroy()' which doesn't actually recurse over its child expressions (via StmtIterator), as those expressions are owned by the Decls and Types (which are destroyed elsewhere). This fixes a crasher reported in <rdar://problem/7487294>.
