2012-08-28[ms-inline asm] Have generateAsmString() return the AsmString computed by Sema.Chad Rosier
We still need to translate the string, but this at least gets us one step closer to using the more general EmitAsmStmt() codegen function. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162785 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[ms-inline asm] Add constraints to MSAsmStmt. We don't currently computeChad Rosier
the constraints, so in the interim we speculatively assume a 'r' constraint. This is expected to work for most cases on x86. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162784 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-28[ms-inline asm] Rename EmitGCCAsmStmt to EmitAsmStmt and have it accept Chad Rosier
AsmStmts. This function is only used by GCCAsmStmts, however. Constraints need to be properly computed before MSAsmStmts can use EmitAsmStmt. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162776 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-28[analyzer] Don't purge dead symbols at the end of calls if -analyzer-purge=none.Jordan Rose
No test case since this is a debug option that we will never turn on by default since it makes the leak checkers much less useful. (We'll only report leaks at the end of analysis if -analyzer-purge=none.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162772 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-28Warn about suspicious implicit conversions from floating point to boolHans Wennborg
This warns in two specific situations: 1) For potentially swapped function arguments, e.g. void foo(bool, float); foo(1.7, false); 2) Misplaced brackets around function call arguments, e.g. bool InRange = fabs(a - b < delta); Where the last argument in a function call is implicitly converted from bool to float, and the function returns a float which gets implicitly converted to bool.

2012-08-28[analyzer] Rename addTrackNullOrUndefValueVisitor to trackNullOrUndefValue.Jordan Rose
This helper function (in the clang::ento::bugreporter namespace) may add more than one visitor, but conceptually it's tracking a single use of a null or undefined value and should do so as best it can. Also, the BugReport parameter has been made a reference to underscore that it is non-optional. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162720 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[analyzer] Refactor FindLastStoreBRVisitor to not find the store ahead of time.Jordan Rose
As Anna pointed out to me offline, it's a little silly to walk backwards through the graph to find the store site when BugReporter will do the exact same walk as part of path diagnostic generation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162719 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[analyzer] If the last store into a region came from a function, step into it.Jordan Rose
Previously, if we were tracking stores to a variable 'x', and came across this: x = foo(); ...we would simply emit a note here and stop. Now, we'll step into 'foo' and continue tracking the returned value from there. <rdar://problem/12114689> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162718 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[analyzer] Rename CallEvent::mayBeInlined to CallEvent::isCallStmt.Jordan Rose
The two callers are using this in order to be conservative, so let's just clarify the information that's actually being provided here. This is not related to inlining decisions in any way. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162717 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-27This is a temporary solution until we have a better way toManuel Klimek

I'm not entirely happy about this script, but as it saves a lot of work in keeping the docs up to date with the actual code I think checking it in makes sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162690 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-27[analyzer] Don't inline constructors for objects allocated with operator new.Jordan Rose
Because the CXXNewExpr appears after the CXXConstructExpr in the CFG, we don't actually have the correct region to construct into at the time we decide whether or not to inline. The long-term fix (discussed in PR12014) might be to introduce a new CFG node (CFGAllocator) that appears before the constructor.
