llvm-svn: 41359
 2007-08-24 15:17:59 +00:00
Devang Patel 4bc9298f2a It is not safe to execute split condition's true branch first all the time. If split 
condition predicate is GT or GE then execute false branch first.

 2007-08-24 06:17:19 +00:00
Devang Patel 4be56a5d12 Reject ICMP_NE as index split condition.

 2007-08-24 05:36:56 +00:00
Chris Lattner 2da04b3322 completely refactor codegen of scalar expressions out into its own CGExprScalar.cpp file. 
This patch temporarily breaks compound assignment operators, but greatly simplifies many
things.

 2007-08-23 23:43:33 +00:00
Chris Lattner 247ef955bc in the truncation case, make sure to propagate the sign correctly, this 
fixes an assertion on:
void f (int z) { switch (z) { case ~0ULL: case -1: return; } }

testcase from Neil.

Steve Naroff 8ddb23a6c5 Support '~' for complex conjugation. This is a GCC extension. 
This following now compiles without error...

_Complex unsigned X, Y;
_Complex double x, y;
void test2(int c) {
  X = ~Y;
  x = ~y;
}

llvm-svn: 41341
 2007-08-23 22:06:40 +00:00
Chris Lattner 7b939cf606 fix a bug where we would type 0ULL as unsigned instead of unsigned long long 
llvm-svn: 41340
 2007-08-23 21:58:08 +00:00
Chris Lattner e5b60445e7 Pretty print as: 
"case sizeof x:"
instead of:
  "case sizeofx:"

llvm-svn: 41339
 2007-08-23 21:46:40 +00:00
Chris Lattner 9568880c3e sizeof(x) doesn't require x to be an i-c-e for sizeof to be an i-c-e. Thanks to Neil for pointing this out.

Ted Kremenek 9aae513318 No functionality change. Moved visitor methods for CFGBuilder out-of-line 
from the class declaration.  This enables a nice view of what visitor methods
have been implemented.

llvm-svn: 41337
 2007-08-23 21:42:29 +00:00
Chris Lattner 1aaab49a3e add support for codegen of calls returning complex. 
llvm-svn: 41336
 2007-08-23 21:38:16 +00:00
Steve Naroff 9e1e551c01 Remove a FIXME, allowing ++/-- on Complex types (a GCC extension). 
Now, the following test case succeeds...

_Complex double x, y;
void test2(int c) {
  ++x;
}

llvm-svn: 41335
 2007-08-23 21:37:33 +00:00
Ted Kremenek 04cca64f8c moved CFGBuilder into an anonymous namespace 
llvm-svn: 41334
 2007-08-23 21:26:19 +00:00
Steve Naroff 4e1f80d255 - Cleanup "hack" comment and fix typos. 
- Use getLang().ObjC2 when appropriate.

llvm-svn: 41333
 2007-08-23 19:56:30 +00:00
Ted Kremenek 879d8e1f77 Added support for switch, default, and case statements in source-level CFGs. 
llvm-svn: 41332
 2007-08-23 18:43:24 +00:00
Chris Lattner 67998451c7 finish off switch case overlap checking, adding support for 
verifying case ranges.

llvm-svn: 41331
 2007-08-23 18:29:20 +00:00
Steve Naroff 7c34817902 Add helper functions Token::isObjCAtKeyword() and Token::getObjCKeywordID(). 
Convert all clients to the new cleaner, more robust API.

llvm-svn: 41330
 2007-08-23 18:16:40 +00:00
Ted Kremenek 13fdfe99cd Refactored "getSubStmt" and "SubStmt" from the CaseStmt and DefaultStmt 
class to their common parent class SwitchCase.

llvm-svn: 41329
 2007-08-23 18:04:38 +00:00
Chris Lattner f81460f99c detect and diagnose empty case ranges: 
switch.c:16:8: warning: empty case range specified
  case 100 ... 99: ;  // expected-warning {{empty case range}}
       ^~~~~~~~~~

 2007-08-23 17:48:14 +00:00
Ted Kremenek 9ee3bcf81c For gotos, breaks, and continues where we cannot find a target successor 
block (because we are creating a CFG from an incomplete AST) we now
(gracefully) have a block ending with such statements not have any successors
instead of firing an assertion.

 2007-08-23 17:29:58 +00:00
Duncan Sands a0f12c5493 Fix this testcase: there are two matches for 
llvm.cttz.i64 because of the declaration of
the intrinsic.  Also, emit-llvm is automatic
and doesn't need to be specified.

llvm-svn: 41326
 2007-08-23 17:22:50 +00:00
Ted Kremenek 9443f5b1e0 Added support for do..while loops in CFG construction. 
llvm-svn: 41325
 2007-08-23 17:15:32 +00:00
Ted Kremenek 07b5b52cd0 Modified CFG to have explicit "Exit" pointer for exit block. This should 
have been committed with my previous patch.

llvm-svn: 41324
 2007-08-23 16:51:52 +00:00
Ted Kremenek 889073f785 Renamed "CFG::BuildCFG" to "CFG::buildCFG" to have more consistent capitalization. 
Added explicit "Exit" CFGBlock pointer to the source-level CFG.

Changed the construction of blocks with "return" statements to have the
return statement appear both as a statement in the list of statements for
a CFGBlock as well as appear as a control-flow terminator.  Also removed
the implicit linearization of "return" so that the return value and the
return statement did not appear as separate statements in the block.

Anders Carlsson cb8f832c26 As suggested by Chris, use MatchRHSPunctuation instead of manually looking for a right parenthesis when parsing @encode() and @protocol(). 
llvm-svn: 41321

Chris Lattner 725c6a4279 this test is passing, though it is generating bogus code at the moment. 
llvm-svn: 41314
 2007-08-23 05:47:53 +00:00
Chris Lattner fc1c44ac7d start checking case values of switch stmts more closely. Emit overflow 
warnings when converting case values to the expression type.
