* Calculate the dataGas correctly in the constant optimiserAlex Beregszaszi2018-08-142-3/+2

* Added guards for unknown pragmasAugusto F. Hack2018-08-061-4/+10
| | | | | | | | | | | | | | | Removed push/pop if there was no change to the warnings *in the same file* for a given compiler. This assumes the imported boost headers use a warning stack themselves. The pragmas don't seem to be required anymore, but were not removed to mantain compatibility with older versions of the boost library. Compiled with - clang version 6.0.1 (tags/RELEASE_601/final) - gcc (GCC) 8.1.1 20180531 against: - libboost 1.67.0-5

* Make the Solidity repository standalone.Bob Summerwill2016-08-011-0/+62
| | | | | | | | | | | | | | | | | | | | This commit is the culmination of several months of work to decouple Solidity from the webthree-umbrella so that it can be developed in parallel with cpp-ethereum (the Ethereum C++ runtime) and so that even for the Solidity unit-tests there is no hard-dependency onto the C++ runtime. The Tests-over-IPC refactoring was a major step in the same process which was already committed. This commit contains the following changes: - A subset of the CMake functionality in webthree-helpers was extracted and tailored for Solidity into ./cmake. Further cleanup is certainly possible. - A subset of the libdevcore functionality in libweb3core was extracted and tailored for Solidity into ./libdevcore. Further cleanup is certainly possible - The gas price constants in EVMSchedule were orphaned into libevmasm. - Some other refactorings and cleanups were made to sever unnecessary EVM dependencies in the Solidity unit-tests. - TravisCI and Appveyor support was added, covering builds and running of the unit-tests (Linux and macOS only for now) - A bug-fix was made to get the Tests-over-IPC running on macOS. - There are still reliability issues in the unit-tests, which need immediate attention. The Travis build has been flipped to run the unit-tests 5 times, to try to flush these out. - The Emscripten automation which was previously in webthree-umbrella was merged into the TravisCI automation here. - The development ZIP deployment step has been commented out, but we will want to read that ONLY for release branch. Further iteration on these changes will definitely be needed, but I feel these have got to sufficient maturity than holding them back further isn't winning us anything. It is go time :-)
