* common/math: "optimised" SafeMul and added comment on Exp (#3675)Jeffrey Wilcke2017-02-182-2/+5

* params: core, core/vm, miner: 64bit gas instructionsJeffrey Wilcke2017-02-142-0/+75
| | | | | | | | | | | | | | | | | Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test

* all: fix license headers one more timeFelix Lange2015-07-242-2/+2
| | | | I forgot to update one instance of "go-ethereum" in commit 3f047be5a.
* all: update license headers to distiguish GPL/LGPLFelix Lange2015-07-232-8/+8
| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
