Functions ¶
func ForksWhereOpAdded ¶ added in v0.2.0
ForksWhereOpAdded returns the fork names where a given op is added. If this returns nil, op is invalid.
Types ¶
type InstructionSet ¶ added in v0.2.0
type InstructionSet struct {
// contains filtered or unexported fields
}
InstructionSet is an EVM instruction set.
func FindInstructionSet ¶ added in v0.2.0
func FindInstructionSet(name string) *InstructionSet
FindInstructionSet resolves a fork name to a set of opcodes.
func (*InstructionSet) AllOps ¶ added in v0.2.1
func (is *InstructionSet) AllOps() []*Op
AllOps returns all operations.
func (*InstructionSet) ForkWhereOpRemoved ¶ added in v0.2.0
func (is *InstructionSet) ForkWhereOpRemoved(op string) string
ForkWhereOpRemoved returns the fork where a given op was removed from the instruction set. This is intended to be called when op is known to not exist. Note this will return an empty string in several cases:
- op is invalid
- op is valid, but does not appear in lineage of instruction set
- op is valid and exists in instruction set
func (*InstructionSet) Name ¶ added in v0.2.0
func (is *InstructionSet) Name() string
Name returns the canonical instruction set name.
func (*InstructionSet) OpByCode ¶ added in v0.2.0
func (is *InstructionSet) OpByCode(code byte) *Op
OpByCode resolves an opcode by its code.
func (*InstructionSet) OpByName ¶ added in v0.2.0
func (is *InstructionSet) OpByName(opname string) *Op
OpByName resolves an opcode by its name. Name has to be all uppercase.
func (*InstructionSet) Parents ¶ added in v0.2.1
func (is *InstructionSet) Parents() []string
Parents returns the parent fork chain of the instruction set.
func (*InstructionSet) PushBySize ¶ added in v0.2.0
func (is *InstructionSet) PushBySize(size int) *Op
PushBySize resolves a push op by its size.
func (*InstructionSet) SupportsPush0 ¶ added in v0.2.0
func (is *InstructionSet) SupportsPush0() bool
SupportsPush0 reports whether the instruction set includes the PUSH0 instruction.
type InstructionSetDef ¶ added in v0.2.0
type InstructionSetDef struct {
Names []string // all names of this instruction set
Parent string
Added []*Op
Removed []*Op
}
InstructionSetDef is the definition of an EVM instruction set.
func (*InstructionSetDef) Name ¶ added in v0.2.0
func (def *InstructionSetDef) Name() string
Name returns the canonical name.
type Op ¶ added in v0.2.0
type Op struct {
Name string
Code byte
// Flags:
// - Push is set for PUSHx
// - Term is set for instructions that end execution
// - Jump is set for all jumps
// - Unconditional is set for unconditional jumps
// - JumpDest is set for JUMPDEST
Push, Term, Jump, Unconditional, JumpDest bool
}
Op is an EVM opcode.
