If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke --- core/vm/jump_table.go | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'core/vm/jump_table.go') diff --git a/core/vm/jump_table.go b/core/vm/jump_table.go index 255c4f189..4e997f636 100644 --- a/core/vm/jump_table.go +++ b/core/vm/jump_table.go @@ -16,7 +16,11 @@ package vm -import "math/big" +import ( + "math/big" + + "github.com/ethereum/go-ethereum/params" +) type jumpPtr struct { fn instrFn @@ -25,7 +29,7 @@ type jumpPtr struct { type vmJumpTable [256]jumpPtr -func newJumpTable(ruleset RuleSet, blockNumber *big.Int) vmJumpTable { +func newJumpTable(ruleset *params.ChainConfig, blockNumber *big.Int) vmJumpTable { var jumpTable vmJumpTable // when initialising a new VM execution we must first check the homestead -- cgit v1.2.3
