2012-02-12Update for LLVM changes - there is no more "unwind" instruction.Peter Collingbourne

2012-02-01Second compatability fix for SwitchInst refactoring (added compatability ↵Stepan Dyatkovskiy
with llvm versions < 3.1). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@149528 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Compatability fix for SwitchInst refactoring.Stepan Dyatkovskiy
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want. What was done: 1. Changed semantics of index inside the getCaseValue method: getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous. 2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned. 3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment. 4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst. 4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor. 4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor. Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@149484 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Nice patch by Gang Hu, Heming Cui and Junfeng Yang fixing a memoryCristian Cadar
leak in KLEE. From Gang Hu: "The memory leak is caused by two reasons. First, the MemoryObject objects are not freed, until the MemoryManager is destroyed. Second, when KLEE allocates a non-fixed MemoryObject object, KLEE also allocates a block of memory which is the same as the object's size. This block of memory is never freed. So, this patch generally does reference counting on the MemoryObject objects, and frees them as soon as the reference count drops to zero." Many thanks to Paul Marinescu as well, who tested this patch thoroughly on the Coreutils benchmarks. On 1h runs, the memory consumption typically goes down by 1-5%, but some applications which see more significant gains. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@148402 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-11This is a workaround for the infinite loop reported at Cristian Cadar
http://keeda.stanford.edu/pipermail/klee-dev/2011-August/000723.html KLEE needs to use --fno-builtin when compiling its version of memset. However, this patch also adds the workaround suggested by Paul in the thread above, since support for --fno-builtin was added to llvm-gcc only after LLVM 2.9 was released.

2011-07-20Deprecate LLVM_VERSION_MAJOR and LLVM_VERSION_MINOR in favour ofPeter Collingbourne
version codes. This makes the preprocessor-based version tests more concise and less error prone.

This patch changes the build system to use its own copy of Makefile.rules (taken from a recent svn snapshot). Also added a --with-llvm-build-mode flag and changed the default runtime library configuration to Release+Asserts. Makefile.rules was modified to support --with-llvm-build-mode and older versions of LLVM (tested 2.7 and 2.8). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@131584 91177308-0d34-0410-b5e6-96231b3b80d8
