Solidity, the Smart Contract Programming Language
There are features marked as deprecated and planned to be removed, many of them in the next breaking release v.0.9, which are listed in #15795 . We also need to...
Partially solves #15795 and #14770.
When assigning a newly pushed (and thus empty) dynamic storage array to another, the IR-based pipeline (`--via-ir`) generates less efficient code compared to the legacy pipeline. We discovered this inefficiency...
## Environment - Compiler version: solc 0.8.31 ## Steps to Reproduce Compile the following code using the command `solc a.sol --bin --optimize --no-optimize-yul` ``` contract C { struct A {...
evmasm peephole optimizer will apply EOF-only optimization passes, like IsZeroIsZeroRJumpI, that will never apply in non-EOF bytecodes. There should be a check to exclude running these passes ahead of time...
## Description The following code triggers an ICE when compiling with `--ir`. I think the issue comes from passing a function type that is not identical but implicitly convertible to...
## Abstract For implementing deployments and upgrades for ERC-2535 Diamonds it is necessary to get all the function selectors of a contract so they can be added to the diamond...
## Description The compiler terminates with a `Yul assertion failed: ./libyul/AsmAnalysis.cpp(147)` when trying to compile the program below via the `solc` CLI with the following Yul optimization sequence `[eT]j[t]s:O`. The...
evmasm::AssemblyItem::operator== is pretty hot, especially in the peephole optimizer: https://github.com/argotorg/solidity/blob/08c4e0c6cfab9d6f303fefbf0ad081e06fa4a532/libevmasm/AssemblyItem.h#L248-L252 This operator calls hasInstruction() twice, once in the actual operator, and the second time in the instruction() solAssert: https://github.com/argotorg/solidity/blob/08c4e0c6cfab9d6f303fefbf0ad081e06fa4a532/libevmasm/AssemblyItem.h#L218 This...
Each type of variable has a different slot size. What is the size (in bits) for each type? Where can I find the help documentation for this? How does the...
