Tom Care ea7c48ccf7 Updated scan-build: 
- Idempotent operations are on by default, to match --analyze in the driver.
- Integrated stats calculation based on parsing warnings emitted with the -analyzer-stats flag. The new -stats flag enables this.
- New -maxloop flag to pass down a maxloop value to the analyzer.

Evan Cheng 2fb20b1d37 ARM instruction itinerary fixes: 
1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones.
2. Cortex-a9 is out-of-order so model all read cycles as cycle 1.
3. Lots of other random fixes for A8 and A9.

Ted Kremenek b0e7d77729 Include changes to VisitCXXMemberCallExpr (call visitor functions). 
llvm-svn: 115120
 2010-09-30 01:06:29 +00:00
Ted Kremenek e18dd0a84e Change CheckerVisitor so that [Pre,Post]VisitCallExpr only handles CallExprs for simple C functions, not 
all CallExprs (including CXXMemberCallExpr, etc.).  Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.

Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.

Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.

Sebastian Redl 517523014d In MeasureTokenLength, the FileLoc supplied to the lexer must point to the start of the buffer, or we risk overflow.

Tom Care 2f0419e1f8 AnalyzerStatsChecker improvements: 
- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.

Owen Anderson 6d33f59952 Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also 
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

Douglas Gregor 4ed49f375d When performing template argument deduction of a function template 
against a function type, be sure to check the type of the resulting
function template specialization against the desired function type
after substituting the deduced/defaulted template arguments. Fixes PR8196.

Owen Anderson 0cd522428c UnreachableBlockElim could incorrectly return false when it had not modified the CFG, but HAD modified some PHI nodes. Fixes PR8174. 
llvm-svn: 115083
 2010-09-29 20:57:19 +00:00
Owen Anderson 99c985c37d Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop. 
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.

 2010-09-29 20:05:01 +00:00
Caroline Tice 9068d794fd Fix breakpoint id range testing to disallow ranges that specify breakpoint locations from 
crossing major breakpoint boundaries (must be within a single breakpoint if specifying locations).

Add .* as a means of specifying all the breakpoint locations under a major breakpoint, e.g. "3.*"
means "all the breakpoint locations of breakpoint 3".

Fix error message to make more sense, if user attempts to specify a breakpoint command when there
isn't a target yet.
