core/vm: use uint256 in EVM implementation (ethereum#20787)
* core/vm: use fixed uint256 library instead of big * core/vm: remove intpools * core/vm: upgrade uint256, fixes uint256.NewFromBig * core/vm: use uint256.Int by value in Stack * core/vm: upgrade uint256 to v1.0.0 * core/vm: don't preallocate space for 1024 stack items (only 16) Co-authored-by: Martin Holst Swende <[email protected]>
-
core/vm: clean up contract creation error handling (ethereum#22766)
Do not keep separate flag for "max code size exceeded" case, but instead assign appropriate error for it sooner.
-
core/vm: fix interpreter comments (ethereum#22797)
* Fix interpreter comment * Fix comment

-
core/vm: rework jumpdest analysis benchmarks (ethereum#23499)
* core/vm: rework jumpdest analysis benchmarks For BenchmarkJumpdestOpAnalysis use fixed code size of ~1.2MB and classic benchmark loop. * core/vm: clear bitvec in jumpdest analysis benchmark
-
-
core/vm, core/state/snapshot: remove unused code (ethereum#23956)
* core/state/snapshot: remove wiper functionality * core/vm: remove unused 'unofficial' opcodes

-
core/vm: simplify error handling in interpreter loop (ethereum#23952)
* core/vm: break loop on any error * core/vm: move ErrExecutionReverted to opRevert() * core/vm: use "stop token" to stop the loop * core/vm: unconditionally pc++ in the loop * core/vm: set return data in instruction impls
-
core/vm: rename SHA3 instruction to KECCAK256 (ethereum#23976)
This was proposed in 2016, Solidity uses this since 2017, and evmone and other VMs use the keccak256 name. This brings geth in line with those.

…ons (ethereum#23970) * core/vm: Move interpreter.ReadOnly check into the opcode implementations Also remove the same check from the interpreter inner loop. * core/vm: Remove obsolete operation.writes flag * core/vm: Capture fault states in logger Co-authored-by: Martin Holst Swende <[email protected]> * core/vm: Remove panic added for testing Co-authored-by: Martin Holst Swende <[email protected]>
-
core/vm: rename opSuicide to opSelfdestruct (ethereum#24022)
The opcode was renamed in the codebase in 2017, but the functions were kept unchanged.

…hereum#24026) * core/vm: Remove interpreter loop interruption check * core/vm: Unit test for interpreter loop interruption * core/vm: Check for interpreter loop abort on every jump

core/vm: reverse bit order in bytes of code bitmap (ethereum#24120)
* core/vm: reverse bit order in bytes of code bitmap This bit order is more natural for bit manipulation operations and we can eliminate some small number of CPU instructions. * core/vm: drop lookup table
-
core/vm: make INVALID a defined opcode (ethereum#24017)
* core/vm: Define 0xfe opcode as INVALID * core/vm: Remove opInvalid as opUndefined handles it Co-authored-by: Alex Beregszaszi <[email protected]>

core/vm: optimize Memory.Set32 (ethereum#24847)
* core/vm: remove unnecessary memset for Memory.Set32 * core/vm: optimize Memory.Set32
-
core/vm: better handle error on eip activation check (ethereum#25131)
* core/vm: correct logic for eip check of NewEVMInterpreter * refactor
-
core/vm: performance tweak of
OpCode.String()(ethereum#28453)make `opCodeToString` a `[256]string` array Co-authored-by: lmittmann <[email protected]>
