Alexander Arlt fc7fb3cb7d [ewasm] Polyfill: callvalue, gasprice & difficulty. 2021-04-23 15:54:10 +01:00
Alex Beregszaszi e39433198d Remove the usage of boost::noncopyable 
Prior to this half of the codebase used explicit deleted copy constructors, the others used boost::noncopyable.

Harikrishnan Mulackal f162c484ca Merge pull request #11026 from ethereum/resolve-keccak 
Evaluate ``keccak256(a, const)``, when the value at memory location ``a`` is known at compile time and ``const <= 32``
 2021-04-22 19:18:19 +02:00
hrkrshnn b599235b8d Skip resolving Keccak if AST contains msize. 
Also a refactoring changing `m_optimizeMLoad` to `m_containsMSize`.
 2021-04-22 18:19:47 +02:00
hrkrshnn 3bc4f5708a Evaluate keccak(a, const) if value at memory location a is known 
Here the value of constant can be at most 32.

hrkrshnn 011f8d3ff7 Changed the type of gas calculation to bigint instead of size_t 
Since the gas calculation can involve multiplication by ``--optimize-runs``, it is possible that
`size_t` is not enough to represent the total gas.
 2021-04-22 18:19:47 +02:00
hrkrshnn 94f9410abe Added hashFunction to Dialect. For EVMDialect, it is keccak256 
In a later PR, the functions `storageLoadFunction`, `storageStoreFunctions`, etc will be refactored
to return a YulString instead of a pointer to a BuiltinFunction.

hrkrshnn 0100f48e05 FunctionSpecializer: skip specializing recursive functions 
This avoids potential pathological behaviour, like in Ackermann function.
 2021-03-29 11:02:31 +02:00
hrkrshnn 45a3747701 Added FunctionSpecializer to the optimization suite 2021-03-29 11:02:18 +02:00
hrkrshnn 22ebdc7438 Implemented FunctionSpecializer 
Optimiser step that specializes the function with its literal arguments.
 2021-03-29 11:02:18 +02:00
hrkrshnn 8564d08228 Added a helper class FunctionCopier in ASTCopier 
Helper class that creates a copy of the function definition, replacing the names of the variable
declaration with a new name.
 2021-03-29 11:02:18 +02:00
hrkrshnn b42fc2015c NameCollecter can now only collect VariableDeclarations 
This is done to help with the optimizer step FunctionSpecializer
 2021-03-25 11:49:16 +01:00
hrkrshnn 6d9e9e1b1e Fix small bug in GasMeter calculation in creation context 
Old calculation did not ignore `optimize-runs` parameter, when creation code gas computations were
done. This would lead to expanding values such as `shl(180, 1)` inside constructor code, even for
the default value for `--optimize-runs`, i.e., 200.

Alex Beregszaszi ded5d721d2 Turn unreachable error into assertion 2021-02-16 10:59:22 +00:00
Christian Parpart 32ba5f5ae7 libsolidity: Extend the AST for named AST nodes in order to get precise locations for names. 
The actual SourceLocation on an ASTNode is representing the whole
ASTNode whereas in an LSP (for example) you are also interested in the
SourceLocation of a name of a construct (e.g. variable decarlation, function definition, ...).

This also properly encodes non-existend sources as `-1` in the JSON output (eliminating the use of `numeric_limits<size_t>::max()`).
