2017-07-20Merge pull request #657 from delcypher/vectorized_instructionsCristian Cadar
Implement basic support for vectorized instructions.
2017-07-20Replace assertions of types on LLVM instructions in the Executor with aDan Liew
pass that checks these assertions. This improves several things. * This pass provides more friendly messages than assertions in that it just emits a warning and carries on checking the rest of the instructions. * The takes the checks outside of the Executor's hot path and so avoids checking the same instruction multiple times. Now each instruction is only checked once just before execution starts. The disadvantage of this approach is the check for invariants we expect to hold have been pulled far away from where we expect them to hold. After discussion with @ccadar and @MartinNowack it was decided we will take this hit to readability for better performance and simpler code in the Executor.
2017-07-19Implement basic support for vectorized instructions.Dan Liew
We use LLVM's Scalarizer pass to remove most vectorized code so that the Executor only needs to support the InsertElement and ExtractElement instructions. This pass was not available in LLVM 3.4 so to support that LLVM version the pass has been back ported. To check that the Executor is not receiving vector operand types that it can't handle assertions have been added. There are a few limitations to this implementation. * The InsertElement and ExtractElement index cannot be symbolic. * There is no support for LLVM < 3.4.

llvm: get rid of static_casts from iterators
2017-06-16llvm37: introduce type for PassManagerJiri Slaby
In LLVM 3.7, PassManager was moved to the legacy:: namespace. Introduce a type for it and use it in the code. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-06-15llvm: get rid of static_casts from iteratorsJiri Slaby
In commit b7a6aec4eeb4 (convert iterators using static_cast), I switched all implicit casts to static_cast. It turned out that llvm 4.0 banned casting via static_cast. See e.g. 1e2bc42eb988 in the llvm repo what they do. So similarly to the above commit, change all the casts of iterators to "&*" which is what they do in LLVM.

2017-06-12llvm: don't use clEnumValEnd for LLVM 4.0Jiri Slaby
It became unnecessary when defining options and mainly undefined. So introduce KLEE_LLVM_CL_VAL_END as suggested by @delcypher. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-05-24llvm: make KLEE compile against LLVM 3.5 and 3.6Richard Trembecký
Based on work by @ccadeptic23 and @delcypher. Formatting fixed by @snf. Fix compiler warning by @martijnthe. Further fixes by @mchalupa. Refactored, so that changes can be reviewed -- no massive changes in whitespace and in the surrounding code. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-02-28convert iterators using static_castJiri Slaby
Newer versions of LLVM do not allow to implicitly cast iterators to pointers where they point. So convert all such uses to explicit static_cast, the same as LLVM code does. Otherwise we see errors like: lib/Core/Executor.cpp:548:15: error: no viable conversion from 'Module::iterator' (aka 'ilist_iterator<llvm::Function>') to 'llvm::Function *' Function *f = i; ^ ~ Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-02-25llvm: stop using global contextJiri Slaby
It was marked as deprecated long time ago and finally removed in LLVM 3.9. Remove all uses of getGlobalContext and create our own context. Propagate it all over the code then. [v2] use ctx, not C as name Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2014-09-14[LLVM3.5] Don't try to use DEBUG macro without DEBUG_TYPE.Daniel Dunbar
2014-09-13Add KLEE specific DEBUG macros.Daniel Dunbar
- This allows us to build in +Asserts mode even when LLVM isn't (by disabling the checks in that mode). - Eventually it would be nice to just move off of LLVM's DEBUG infrastructure entirely and just have our own copy, but this works for now. - Fixes #150.
2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2014-04-14Tidy up code by using LLVM's V2 path API only and removing usesDan Liew
of old V1 path API. LLVM2.9 supports LLVM's V2 path API. Because that is the minimum version we support we should just use this API everywhere so we reduce the number of #if LLVM_VERSION_CODE macros and duplicated code.

Old Path API was removed
2014-01-17Make KLEE fail in case main function is missingMartin Nowack
Existence of main() function is checked with assertion. This check fails if KLEE is compiled in Release mode.
2013-12-19Optimize inlineChecks functionMartin Nowack
* Just iterate over the instructions which use the function to be inlined * Handle each callsite (e.g. CallInst and InvokeInst)
2013-12-19Allow to specify KLEE-internal functionsMartin Nowack
KLEE provides runtime library functions to do detection of bugs (e.g. overflow). This runtime functions are not the location of the bugs but it is the next non-runtime library function from the stack. Use the caller inside that function to indicate where the bug is.

Make KLEE compile with LLVM 2.3.
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.

2013-08-27Port 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

version codes. This makes the preprocessor-based version tests more concise and less error prone.
