* 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 <martin@swende.se>
Do not keep separate flag for "max code size exceeded" case, but instead assign appropriate error for it sooner.
* Fix interpreter comment * Fix comment
* 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/state/snapshot: remove wiper functionality * core/vm: remove unused 'unofficial' opcodes
* 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
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 <martin@swende.se> * core/vm: Remove panic added for testing Co-authored-by: Martin Holst Swende <martin@swende.se>
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 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: Define 0xfe opcode as INVALID * core/vm: Remove opInvalid as opUndefined handles it Co-authored-by: Alex Beregszaszi <alex@rtfs.hu>
* core/vm: remove unnecessary memset for Memory.Set32 * core/vm: optimize Memory.Set32
* core/vm: correct logic for eip check of NewEVMInterpreter * refactor
make `opCodeToString` a `[256]string` array Co-authored-by: lmittmann <lmittmann@users.noreply.github.com>
