Bhargava Shastry 5d7533b540 Merge pull request #14227 from ethereum/update-codegen-fuzzer 
Stack optimizer fuzzer: Detect stack-too-deep during optimization
 2023-07-03 14:52:27 +02:00
Martin Blicha 29041c8101 Remove ReasoningBasedSimplifier from libyul 
Due to a design decision to move away from a bundled SMT solver,
ReasoningBasedSimplifier in its current form cannot be use any longer.
This is a necessary step to allow a unified way to call solvers using
only SMTLIB interface.

Since this optimization pass has always been marked as highly
experimental and never turned on by default, it should be OK to remove
it.

hrkrshnn 41ce3feb0a test: some tests for push0 
1. `push0_disallowed.yul`: checks if `push0()` is a valid builtin in strict Yul
2. `push0_disallowed.sol`: checks if `push0()` is a valid builtin in inline assembly
3. `push0.sol`: simple semantic test that returns 0
4. `evmone_support.sol`: tests if push0 works properly in evmone
5. Updated some bytecode too large tests to use `shanghai` as version
6. Updated various tests where `push1 0` was hardcoded in different forms / expectations on bytecode
size (`Assembler.cpp`, `GasCosts.cpp`, `SolidityCompiler.cpp`, `SolidityExpressionCompiler.cpp`)

 		ef6ff2f055 Adds support for the EVM version "Paris". 
Deprecates `block.difficulty` and disallow `difficulty()` in inline assembly for EVM versions >= paris.
The change is due to the renaming introduced by EIP-4399 (see: https://eips.ethereum.org/EIPS/eip-4399).
Introduces `block.prevrandao` in Solidity and `prevrandao()` in inline assembly for EVM versions >= paris.
