2013-09-02Implemented runtime check for overshift (controllable with --check-overshiftDan Liew
command line argument). Overshift is where a Shl, AShr or LShr has a shift width greater than the bit width of the first operand. This is undefined behaviour in LLVM so we report this as an error.
2013-09-02Fixed bug where divide by zero bugs would only be detected once in a programDan Liew
even if there were many divide by zero bugs. The fix basically inlines all function calls to klee_div_zero_check() so that each call to klee_report_error() is a unique instruction for each instrumentation of a divide operation. It also seems that inlining the call "magically" fixed the debug information (file and line number) of the instruction so that the debug information on the inlined instructions matches that of the instrumented division instruction. Note that the command line option -emit-all-errors could be used to workaround the bug fixed in this commit.
2013-09-02Fixed multiple definitions of POSIX file functionsMartin Nowack
Function like stat() were defined for 32bit and 64bit version. Added compile time based selection of appropriate version using GNUC macros __x86_64__ and __ppc64__.

2013-08-29Fix compiling issues with llvm 2.9Martin Nowack
Interface for ParseCommandLineOptions changed with LLVM 3.2 preserving constness for pointer to arguments.
2013-08-29Use new PathV2 interface for LLVM 2.9 and higherMartin Nowack
Enable PathV2 interface starting from LLVM 2.9 and do some minor include cleanup.
2013-08-28Modified the buildmode of bitcode libraries.Dan Liew
The Default is Release+Asserts but if you are building KLEE with debug symbols (for example "Release+Debug+Asserts" or "Debug+Asserts") then this breaks because KLEE will look for the bitcode libraries in the wrong place because the RUNTIME_CONFIGURATION macro is not defined to be what KLEE actually builds as. This has been tweaked so that when we build the bitcode libraries the Makefile variable "DEBUG_SYMBOLS" is correctly overridden.

2013-08-27Fix implementation for putcharMartin Nowack
According to manual: putchar() return the character written as an unsigned char cast to an int or EOF on error. Use return value of write to return the correct value for putchar.

2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful
