Jeffrey Wilcke	846d091bd2	core/vm: allocate stack to 1024 ... Pre allocate the stack to 1024 optimising stack pushing, reducing calls to runtime.makeslice and runtime.mallocgc	8 years ago
Jeffrey Wilcke	10582a97ca	core/vm: expose intpool to stack dup method ... Improve the duplication method of the stack to reuse big ints by passing in an existing integer pool.	8 years ago
Jeffrey Wilcke	bbc4ea4ae8	core/vm: improved EVM run loop & instruction calling (#3378) ... The run loop, which previously contained custom opcode executes have been removed and has been simplified to a few checks. Each operation consists of 4 elements: execution function, gas cost function, stack validation function and memory size function. The execution function implements the operation's runtime behaviour, the gas cost function implements the operation gas costs function and greatly depends on the memory and stack, the stack validation function validates the stack and makes sure that enough items can be popped off and pushed on and the memory size function calculates the memory required for the operation and returns it. This commit also allows the EVM to go unmetered. This is helpful for offline operations such as contract calls.	8 years ago
Nick Johnson	781915f183	core/vm: Refactor tracing to make Tracer the main interface ... This CL makes several refactors: - Define a Tracer interface, implementing the `CaptureState` method - Add the VM environment as the first argument of `Tracer.CaptureState` - Rename existing functionality `StructLogger` an make it an implementation of `Tracer` - Delete `StructLogCollector` and make `StructLogger` collect the logs directly - Change all callers to use the new `StructLogger` where necessary and extract logs from that. - Deletes the apparently obsolete and likely nonfunctional 'TraceCall' from the eth API. Callers that only wish accumulated logs can use the `StructLogger` implementation straightforwardly. Callers that wish to efficiently capture VM traces and operate on them without excessive copying can now implement the `Tracer` interface to receive VM state at each step and do with it as they wish. This CL also removes the accumulation of logs from the vm.Environment; this was necessary as part of the refactor, but also simplifies it by removing a responsibility that doesn't directly belong to the Environment.	8 years ago
Jeffrey Wilcke	b196278044	core/vm: added JIT segmenting / optimisations ... * multi-push segments * static jumps segments	9 years ago
Jeffrey Wilcke	ac697326a6	core/vm: reduced big int allocations ... Reduced big int allocation by making stack items modifiable. Instead of adding items such as `common.Big0` to the stack, `new(big.Int)` is added instead. One must expect that any item that is added to the stack might change.	9 years ago
Jeffrey Wilcke	846f34f78b	core/vm, tests: implemented semi-jit vm ... * changed stack and removed stack ptr. Let go decide on slice reuse.	9 years ago
Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago

Gustav Simonsson	c26c8d3a44	Read most protocol params from common/params.json ... * Add params package with exported variables generated from github.com/ethereum/common/blob/master/params.json * Use params package variables in applicable places * Add check for minimum gas limit in validation of block's gas limit * Remove common/params.json from go-ethereum to avoid outdated version of it	10 years ago
