Martin Holst Swende	b566cfdffd	core/evm: avoid copying memory for input in calls (#20177) ... * core/evm, contracts: avoid copying memory for input in calls + make ecrecover not modify input buffer * core/vm: optimize mstore a bit * core/vm: change Get -> GetCopy in vm memory access	5 years ago
Martin Holst Swende	36b78abe61	core/vm: instruction tests (#16327) ... This PR makes it easy to generate and execute testcases for VM arithmetic operations. By enabling and running the testcase TestWriteExpectedValues, a set of json files are created which contain input and output for each arith operation. The test TestJsonTestcases executes all of those tests. While meaningless as is, this PR makes it less risky to make changes (optimizations) to the vm operations, since there will be a larger body of testcases.	6 years ago

Hyung-Kyu Hqueue Choi	0ab54de1a5	core/vm: update benchmarks for core/vm (#17308) ... - Update benchmarks to use a pool of int pools. Unless benchmarks are aborted with segmentation fault. Signed-off-by: Hyung-Kyu Choi <hqueue@users.noreply.github.com>	6 years ago
Guillaume Ballet	7abedf9bbb	core/vm: support for multiple interpreters (#17093) ... - Define an Interpreter interface - One contract can call contracts from other interpreter types. - Pass the interpreter to the operands instead of the evm. This is meant to prevent type assertions in operands.	6 years ago
