mratsim 9fc80cb6c9 Update VMTests with Stint, raise Exception for non-implemented Exp and byteOp instead of quitting 2018-05-11 18:16:35 +02:00

Migrate from ttmath to stint (#24) 
* Constants and accounts compile as standalone

* Mass replace ttmath by Stint

* Adapt utils_numeric proc

* Adapt memory.nim

* Deactivate "ValidationError" test that requires pow(2, 256) function

* Fix state_db toByteArrayBE

* Fix more getUint toInt conversion

* Remove absolute value ambiguous call

* Stub-ify proc and opcode that requires pow - https://github.com/status-im/nim-stint/issues/37

Few steps forward vm_tests (#15) 
* Enable vm_tests, remove usage of from keyword as a variable name

* Fix Genesis types and use the new EthTime

* Add a new VMKind enum (py-evm vmclass runtime type)

* renaming block_obj to block_types

* chain.BlockHeader and utils.header.Header are the same thing (BlockHeader in py-evm)

* For now blockNumbers are UInt256

* EoD merge: vm_test compiles and does not throw computation error

* running full transactions is too early

Add opcode tests (#4) 2018-04-06 16:25:01 +02:00
Alexander Ivanov 8be1a51c64 Fix 80 arithmetic gas cost tests, improve exp gas cost 2018-02-28 17:06:05 +02:00
Alexander Ivanov f179695341 Fix arithmetic and save test progress in VMTests.md 2018-02-27 20:10:45 +02:00
Alexander Ivanov dc365b2e23 Fix tests 2018-02-26 14:00:15 +02:00
Alexander Ivanov 99921f38cb Pass more tests, use UInt256 more often 
82 / 189 arithmetic
55 / 62 logic
77 / 78 stack

Most errors are the same sstore gascost bug, also next work on flow and memory

Alexander Ivanov 9c056b85de Pass first fixtures tests 
Todo

Pass most VM opcode tests that we can (of those that don't depend
too much on porting the whole py-evm)

Simplify a bit the current py-evm-inspired internal loop arch
