2018-10-26llvm5: handle getOrInsertFunction terminatorJiri Slaby
llvm 5 does not terminate getOrInsertFunction parameters with NULL, take care of that. Since commit 9d54400bba7eb04bca80fce97fa170452d19eaf1. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-24ShiftChecker: Instrument shift instructions only onceMartin Nowack
As the shift checker could be executed multiple times, we need to avoid that shift instructions are instrumented multiple times as well. Mark the instrumented instruction using metadata and avoid it in successive runs.
2018-10-24ShiftChecker: Avoid unneeded checksMartin Nowack
Do not instrument shift operations with constant shift operations that are smaller than the type size.
2018-10-24ShiftCheck: Use llvm::Builder instead of Inst::Create*Martin Nowack
Use llvm::Builder instead of Inst::Create* to create instruction. This handles metadata automatically and does instruction folding if possible. Updated to C++11 and clang-formatted.
2018-10-24DivCheck do not instrument multiple timesMartin Nowack
DivChecker can be executed multiple times due to the new linking process. Avoid instrumenting div instructions multiple times by annotating checked instructions with marker. Only unmarked div instructions will be instrumented.
2018-10-24DivCheck Skip unneeded checksMartin Nowack
Do not instrument divisions which do have a constant non-zero value.
2018-10-24Use llvm::Builder for DivCheck instrumentationMartin Nowack
Use llvm::Builder instead of raw `*Inst::create()` functions. Builder automatically manages metadata (e.g. debug, TBAA, ..) such that we don't have to take care of this automatically. Updated code to C++11 and clang-formated it.
2017-07-23Remove support for LLVM < 3.4Martin Nowack
Request LLVM 3.4 as minimal requirement for KLEE
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.

2017-02-28convert 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] Update for CallSite.h move into IR/.Daniel Dunbar
2014-05-29Remove #include <iostream> to avoid static constructorsMartin Nowack
iostream injects static constructor function into every compilation unit. Remove this to avoid it.
2013-12-19Remove old algorithm for acquiring debug info. Since LLVM 2.7,Dan Liew
debug information is attached directly to most instructions so the simpler algorithm added in 5ecfd6e2fd5becc10be355b3a20d014e76e40518 can be used. Since support for LLVM version < 2.9 has been removed the old algorithm should be removed. This has been tested with LLVM 2.9 and LLVM 3.3

2013-12-06Deprecate LLVM 2.8 and lowerMartin Nowack
2013-10-29Merge pull request #26 from delcypher/fix_divide_by_zeroPaul
Fixed bug where divide by zero bugs would only be detected once in a program
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.
2013-08-27Port 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

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. Also, fix the version tests in lib/Expr/Parser.cpp (immutable zext and trunc were introduced in LLVM 2.9); now 2.9 passes "make test". git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@135583 91177308-0d34-0410-b5e6-96231b3b80d8
