2018-02-01llvm50: use auto variable instead of SwitchInst::CaseItJiri Slaby
llvm50 changed the semantics of SwitchInst::CaseIt and started using "auto" variable type. So use it here too for all versions greater than 3.4 -- 3.4 does not support this semantics yet. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2017-10-04Remove Autoconf/Makefile build system and adjust the TravisCIDan Liew
configuration, TravisCI scripts and Dockerfile build appropriately. There are a bunch of clean ups this enables but this commit doesn't attempt them. We can do that in future commits.
2017-10-03Silenced some warnings about unused variables when assertions are disabled.Cristian Cadar
2017-09-22Merge pull request #748 from ccadar/optionsCristian Cadar
Added support for hiding command-line options

2017-08-07Untabify this file, which was using a mix of spaces and tabs for alignment.Cristian Cadar
2017-08-07Added checks for div/mod by zero and overshifts in constant expressions. ↵Cristian Cadar
Such div/mod by zero expressions would previously crash KLEE. Added two test cases, one for div/mod by zero, the other for overshift. This fixes the bug reported in #268.

2017-07-31Fix build for FreeBSD.Tatiana Tikhomirova
On FreeBSD <sys/capabilities.h> is present in libc, so we don't require libcap there. Close and write functions are located in <unistd.h>.
2017-07-29Added an optional KInstruction* argument to evalConstant and ↵Cristian Cadar
evalConstantExpr which allows us to print the location associated with the constant in any error messages. Added a test case for the unsupported features for taking the address of a label, which exercises the patch.
2017-07-29Added another variant of printFileLine in KInstruction that returns the ↵Cristian Cadar
location as a string. Also added const qualifier to the printFileLine functions
2017-07-26Now that LLVM 2.9 is gone, we can use cl::bits instead of cl::listCristian Cadar
2017-07-25Merge pull request #725 from ccadar/foldCristian Cadar
Refactored some code related to constant evaluation
2017-07-25This commit simply moves evalConstant to ExecutorUtil (where ↵Cristian Cadar
evalConstantExpr also resides), as suggested by an old comment.
2017-07-25Added the const qualifier to the keys in the constantMapCristian Cadar

Request LLVM 3.4 as minimal requirement for KLEE
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.
2017-07-20Core: TimingSolver, use TimerStatIncrementerJiri Slaby
Do not opencode what we already have in TimerStatIncrementer. This simplifies the code a lot and makes transition to LLVM 4.0 a lot easier. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
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.
2017-07-19Fixes bug in TreeStreamWriter::write reported by @gladtbx in #562. Also ↵Cristian Cadar
removes commented out code from that function.
2017-07-18Use assembly line for printing debug informationMartin Nowack

llvm: get rid of static_casts from iterators
2017-07-08Corrected comment of Z3Solver classAndrew Santosa
2017-06-16move module loading into external functionJörg Thalheim
- having an explicit function which is defined for multiple llvm versions separately increases readability. - also: error handling was simplified - Personal motivation: being able to use this functionality in unit tests fixes #561 related to #656
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>

2017-06-15llvm37: do not copy DILocation to getDSPIPathJiri Slaby
DILocation is not copyable in LLVM 3.7. So, pass it as reference and make it const given we do not write to it. 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>
