Devang Patel 887db2d832 Remove dead code. 
llvm-svn: 41295
 2007-08-22 21:07:41 +00:00
Ted Kremenek 1c65be13cc Added preliminary support for while loops within source-level CFGs. 
Adjusted printing of source-level CFGs to account that the entry block
may not be the first block in the list of blocks a CFG object maintains.

Ted Kremenek 88dea224c1 Added explicit pointer within class CFG to the Entry block. 
Before we assumed that the first block in the list of blocks was the entry
block, but this has posed hurdles during CFG construction.

Devang Patel 31206b56d5 Cosmetic change 
"True Loop" and "False Loop" naming terminology to refer two loops
after loop cloning is confusing. Instead just use A_Loop and B_Loop.

Andrew Lenharth beb80a9832 move this check. ppc outputs .no_dead_strip properly

Steve Naroff f1bc45b1d1 Finish up method prototype parsing. 
Next step...starting installing class names into the type namespace (so we can start parsing Cocoa headers).

Devang Patel 90da534987 Refactor loop condition check in a separate function. 
llvm-svn: 41282
 2007-08-22 18:27:01 +00:00
Ted Kremenek 7e776b1d9c Added CFG support for: for loops 
In CFG dumper, refactored the code to print block terminators into a
StmtVisitor.

Added the method "FinishBlock" to CFGBuilder to do the reversal of statements
in a block instead of calling "reverseStmts" for a block directly.  This
was necessary to fix a bug in how blocks with labels were being processed
(some cases would cause the statements to be reversed twice).  FinishBlock
detects blocks that start with labels and doesn't do a second reversal.

Devang Patel cd8beb7645 Fix thinko. 
Starting value of second loop's induction variable can not be lower 
then starting value of original loop's induction variable.

 2007-08-22 18:07:47 +00:00
Steve Naroff 99264b4b04 Add support for parsing method prototypes (and other stuff required by @interface). 
Still need to finish Parser::ParseObjCMethodDecl(). Before I do, I need to do a minor
refactoring of ParseDeclarationOrFunctionDefinition(), to disallow function definitions.
At the moment, @inteface allows function defs (which is incorrect).

 2007-08-22 16:35:03 +00:00
Ted Kremenek de979aeff3 Changed data structure recording the CFG blocks that need to be backpatched 
to labeled blocks from a list to a vector.

the selection statements and iteration statements.  Add
spec citations.

CFGBlock& instead of CFGBlock*.

dispatch to walk the AST.

Ted Kremenek 4aa1e8b3b8 Added CFG infrastructure (CFG.cpp and CFG.h) for clang ASTs. 
Added builder code to translate ASTs to CFGs.  This currently supports
if, return, and non-control flow statements.

Added pretty-printer to debug CFGs.

Added a "-dump-cfg" option to the clang driver to dump CFGs for code
sent through the frontend.

llvm-svn: 41244
 2007-08-21 18:51:13 +00:00
Chris Lattner 43ba25187b Tweak error recovery for missing semicolon after decl. For this: 
void foo() {
  int x
  if (x) {
  }
}

We now emit:

a.c:5:3: error: parse error
  if (x) {
  ^
1 diagnostic generated.

instead of:

a.c:5:3: error: parse error
  if (x) {
  ^
a.c:9:1: error: expected '}'

^
2 diagnostics generated.
