2011-05-02Implements strncasecmp() checker and simplifies some of the logic around ↵Lenny Maiorani
creating substrings if necessary and calling the appropriate StringRef::compare/compare_lower(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130708 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Use StringRef::substr() and unbounded StringRef::compare() instead of ↵Lenny Maiorani
bounded version of StringRef::compare() because bounded version of StringRef::compare() is going to be removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130425 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Eliminates an assert in the strncpy/strncat checker caused by not validating ↵Lenny Maiorani
a cast was successful. If the value of an argument was unknown, the cast would result in a NULL pointer which was later being dereferenced. This fixes Bugzilla #9806. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130422 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-25Implements the strncmp() checker just like the strcmp() checker, but with ↵Lenny Maiorani
bounds. Requires LLVM svn r129582. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130161 91177308-0d34-0410-b5e6-96231b3b80d8

Luis Felipe Strano Moraes! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129559 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-12This patch adds modeling of strcmp() to the CString checker. Validates ↵Lenny Maiorani
inputs are not NULL and are real C strings, then does the comparison and binds the proper return value. Unit tests included. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129364 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-09strcat() and strncat() model additions to CStringChecker.Lenny Maiorani
Validates inputs are not NULL, checks for overlapping strings, concatenates the strings checking for buffer overflow, sets the length of the destination string to the sum of the s1 length and the s2 length, binds the return value to the s1 value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129215 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-31Adding Static Analyzer checker for mempcpy().Lenny Maiorani
Models mempcpy() so that if length is NULL the destination pointer is returned. Otherwise, the source and destination are confirmed not to be NULL and not overlapping. Finally the copy is validated to not cause a buffer overrun and the return value is bound to the address of the byte after the last byte copied. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128677 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-15[analyzer] Use the new registration mechanism on some of the experimental ↵Argyrios Kyrtzidis
checks. These are: CStringChecker ChrootChecker MallocChecker PthreadLockChecker StreamChecker UnreachableCodeChecker MallocChecker creates implicit dependencies between checkers and needs to be handled differently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125598 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-10Split 'include/clang/StaticAnalyzer' into ↵Ted Kremenek
'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'. This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125251 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-23Chris Lattner has strong opinions about directoryTed Kremenek
layout. :) Rename the 'EntoSA' directories to 'StaticAnalyzer'. Internally we will still use the 'ento' namespace for the analyzer engine (unless there are further sabre rattlings...). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122514 91177308-0d34-0410-b5e6-96231b3b80d8
