mratsim 8d76cab46a Was confused about ∧ in the Yellow paper. Fix #50 - pass 2 new tests. Only 1 arithmetic failure left. 2018-06-13 16:05:52 +02:00

Gas refactoring - decouple opcode logic and gas (#49)
* Decoupling op logic and gas - introduce gasometer, rework opcode declaration

* Remove gas constants for gas opcode computation

* Remove gas constants for precompiled contracts

* make vm_types compile

* Make opcode, call and computation compile

* Distinguish between dynamic and complex gas costs, fix arithmetic

* Fix context and sha3

* update memory and storage ops

* Log opcode uses memory expansion code

* update/stub system_ops with gas costs

* Make test compile. Deactivate stub test_vm

* all tests compiles, opcode fails due to https://github.com/nim-lang/Nim/issues/8007 (const object variant in tables reset at runtime)

* Create an enum without holes - workaround: https://github.com/nim-lang/Nim/issues/8007

* Use arrays instead of tables for GasCosts, remove some unused imports - passing all basic tests!

* Make test_vm_json compile

* Fix test_vm_json - workaround https://github.com/nim-lang/Nim/issues/8015

* fix memory expansion cost bug

* Remove leftover special handling from before GckMemExpansion

* cleanup outdated comment, better align =

* Fix sha3 gas cost not taking memory expansion into account

* Improve gas error reporting of test_vm_json

* Fix gas computation regression due to mem expansion

* mass replace for memExpansion->RequestedMemSize was too eager

* fix log gas cost (no tests :/)

* missed a static FeeSchedule

* static as expression is fickle

Gas & Memory ops refactoring - uses native integer instead of uint256 fixes #35 and #39 (#40)

1st gas refactoring - handle different gas costs in Ethereum forks (#37)
* Start by renaming the fork by chronological order

* initial commit - groundwork: support different gasCosts depending on VMs

* Running VMTests with new gas config - only push32AndSuicide changed

* Introduce newNimbusVM that (temporarily) abstract over Frontier and Tangerine VM creation

* Fix Gas - push32AndSuicide repassing and expXY_success passing - fixes #34

* case sensitive imports (thank you auto-completion) fix Travis on Linux

* Add pre and post EIP-150 tests

* Nimify gas identifiers that supports multiple forks
