|

* Immutable variables with literal number values are considered pure.

Compiler Features:
|
||||
* Command Line Interface: New option ``--experimental-via-ir`` allows switching compilation process to go through
|
||||
the Yul intermediate representation. This is highly experimental and is used for development purposes.
|
||||
* Standard JSON: New option ``settings.viaIR`` allows the same switch as ``--experimental-via-ir`` on the commandline.
|
||||
* Command Line Interface: Report error if file could not be read in ``--standard-json`` mode.
|
||||
* Command Line interface: Report proper error for each output file which could not be written. Previously an exception was thrown, and execution aborted, on the first error.
|
||||
* SMTChecker: Add division by zero checks in the CHC engine.
|
||||
* SMTChecker: Support ``selector`` for expressions with value known at compile-time.
|
||||
* SMTChecker: More precise analysis of external calls using ``this``.
|
||||
* Command Line Interface: New option ``--model-checker-timeout`` sets a timeout in milliseconds for each individual query performed by the SMTChecker.
|
||||
* Standard JSON: New option ``modelCheckerSettings.timeout`` sets a timeout in milliseconds for each individual query performed by the SMTChecker.
|
||||
* Assembler: Perform linking in assembly mode when library addresses are provided.
|
||||
|
||||
|
||||
Bugfixes:
|
||||
* Command Line Interface: Reject duplicate libraries in ``--libraries`` option instead of arbitrarily choosing one.
|
||||
* SMTChecker: Fix lack of reporting potential violations when using only the CHC engine.
|
||||
* SMTChecker: Fix internal error on conversion from string literal to byte.
|
||||
* SMTChecker: Fix internal error when using tuples of rational literals inside the conditional operator.

* SMTChecker: Fix internal error when ``array.push()`` is used as the LHS of an assignment.
|

* Command Line Interface: Fix write error when the directory passed to ``--output-dir`` ends with a slash.
|
||||
* SMTChecker: Fix CHC false positives when branches are used inside modifiers.
|
||||
* Code generator: Fix missing creation dependency tracking for abstract contracts.
|

* NatSpec: Fix internal error when inheriting return parameter documentation but the parameter names differ between base and inherited.

* Standard JSON: Fix library addresses specified in ``libraries`` being used for linking even if the file names do not match.

It is possible to obtain the address of a library by converting
|
||||
the library type to the ``address`` type, i.e. using ``address(LibraryName)``.
|
||||
|

As the compiler cannot know where the library will be
|
||||
deployed at, these addresses have to be filled into the
|
||||
final bytecode by a linker
|
||||
(see :ref:`commandline-compiler` for how to use the

commandline compiler for linking). If the addresses are not
|
||||
given as arguments to the compiler, the compiled hex code
|
||||
will contain placeholders of the form ``__Set______`` (where
|
||||
``Set`` is the name of the library). The address can be filled

manually by replacing all those 40 symbols by the hex

encoding of the address of the library contract.

Manually linking libraries on the generated bytecode is discouraged, because

in this way, the library name is restricted to 36 characters.

You should ask the compiler to link the libraries at the time

the ``--libraries`` option of ``solc`` or the ``libraries`` key if you use

will contain placeholders of the form ``__$30bbc0abd4d6364515865950d3e0d10953$__``. The placeholder

is a 34 character prefix of the hex encoding of the keccak256 hash of the fully qualified library
|
||||
name, which would be for example ``libraries/bigint.sol:BigInt`` if the library was stored in a file
|
||||
called ``bigint.sol`` in a ``libraries/`` directory. Such bytecode is incomplete and should not be
|
||||
deployed. Placeholders need to be replaced with actual addresses. You can do that by either passing
|

them to the compiler when the library is being compiled or by using the linker to update an already

compiled binary. See :ref:`library-linking` for information on how to use the commandline compiler

Basic usage
|
||||
-----------
|
||||
|
||||
One of the build targets of the Solidity repository is ``solc``, the solidity commandline compiler.
|
||||
Using ``solc --help`` provides you with an explanation of all options. The compiler can produce various outputs, ranging from simple binaries and assembly over an abstract syntax tree (parse tree) to estimations of gas usage.
|
||||
If you only want to compile a single file, you run it as ``solc --bin sourceFile.sol`` and it will print the binary. If you want to get some of the more advanced output variants of ``solc``, it is probably better to tell it to output everything to separate files using ``solc -o outputDirectory --bin --ast-json --asm sourceFile.sol``.
|
||||
|
||||
Optimizer options
|
||||
-----------------
|
||||
|
||||
Before you deploy your contract, activate the optimizer when compiling using ``solc --optimize --bin sourceFile.sol``.
|
||||
By default, the optimizer will optimize the contract assuming it is called 200 times across its lifetime
|
||||
(more specifically, it assumes each opcode is executed around 200 times).

Path remapping

If your contracts use :ref:`libraries <libraries>`, you will notice that the bytecode contains substrings of the form ``__$53aea86b7d70b31448b230b20ae141a537$__``. These are placeholders for the actual library addresses.
|
||||
The placeholder is a 34 character prefix of the hex encoding of the keccak256 hash of the fully qualified library name.

is the path of its source file and the library name separated by ``:``.
|
||||
You can use ``solc`` as a linker meaning that it will insert the library addresses for you at those points:
|
||||
|
||||
Either add ``--libraries "file.sol:Math:0x1234567890123456789012345678901234567890 file.sol:Heap:0xabCD567890123456789012345678901234567890"`` to your command to provide an address for each library or store the string in a file (one library per line) and run ``solc`` using ``--libraries fileName``.
|
||||
|
||||
If ``solc`` is called with the option ``--link``, all input files are interpreted to be unlinked binaries (hex-encoded) in the ``__$53aea86b7d70b31448b230b20ae141a537$__``-format given above and are linked in-place (if the input is read from stdin, it is written to stdout). All options except ``--libraries`` are ignored (including ``-o``) in this case.
|
||||
Either add ``--libraries "file.sol:Math:0x1234567890123456789012345678901234567890 file.sol:Heap:0xabCD567890123456789012345678901234567890"`` to your command to provide an address for each library (use commas or spaces as separators) or store the string in a file (one library per line) and run ``solc`` using ``--libraries fileName``.
|
||||
|
||||
If ``solc`` is called with the option ``--standard-json``, it will expect a JSON input (as explained below) on the standard input, and return a JSON output on the standard output. This is the recommended interface for more complex and especially automated uses. The process will always terminate in a "success" state and report any errors via the JSON output.
|
||||
The option ``--base-path`` is also processed in standard-json mode.
|
||||
|
||||
If ``solc`` is called with the option ``--link``, all input files are interpreted to be unlinked binaries (hex-encoded) in the ``__$53aea86b7d70b31448b230b20ae141a537$__``-format given above and are linked in-place (if the input is read from stdin, it is written to stdout). All options except ``--libraries`` are ignored (including ``-o``) in this case.

.. warning::
|
||||
Manually linking libraries on the generated bytecode is discouraged because it does not update

contract metadata. Since metadata contains a list of libraries specified at the time of

compilation and bytecode contains a metadata hash, you will get different binaries, depending

on when linking is performed.
