CHANGELOG.md

@@ -12,12 +12,24 @@ This is a development pre-release.
 
 Supported `polkadot-sdk` rev: `2503.0.1`
 
+### Changed
+- Remove the broken `--llvm-ir` mode.
+- Remove the unused fallback for size optimization setting.
+- Unlinked contract binaries are emitted as raw ELF objects.
+
 ### Added
 - Line debug information per YUL builtin and for `if` statements.
+- Column numbers in debug information.
 - Support for the YUL optimizer details in the standard json input definition.
+- The `revive-explorer` compiler utility.
+- `revive-yul`: The AST visitor interface.
+- The `--link` deploy time linking mode.
 
 ### Fixed
 - The debug info source file matches the YUL path in `--debug-output-dir`, allowing tools to display the source line. 
+- Incosistent type forwarding in JSON output (empty string vs. null object).
+- The solc automatic import resolution.
+- Compiler panic on missing libraries definition.

+# revive-explorer
+
+The `revive-explorer` is a helper utility for exploring the compilers YUL lowering unit.
+
+It analyzes a given shared objects from the debug dump and outputs:
+- The count of each YUL statement translated.
+- A per YUL statement break-down of bytecode size contributed per.
+- Estimated `yul-phaser` cost parameters.
+
+Example:
+
+```
+statements count:
+	block 532
+	Caller 20
+	Not 73
+	Gas 24
+	Shr 2
+    ...
+	Shl 259
+	SetImmutable 2
+	CodeSize 1
+	CallDataLoad 87
+	Return 56
+bytes per statement:
+	Or 756
+	CodeCopy 158
+	Log3 620
+	Return 1562
+	MStore 36128
+	...
+	ReturnDataCopy 2854
+	DataOffset 28
+	assignment 1194
+	Number 540
+	CallValue 4258
+yul-phaser parameters:
+	--break-cost 1
+	--variable-declaration-cost 3
+	--function-call-cost 8
+	--if-cost 4
+	--expression-statement-cost 6
+	--function-definition-cost 11
+	--switch-cost 3

+//!
+//! # Internals
+//!
+//! After all contracts have been built successfully, the compiler
+//! tries to link the resulting raw ELF object files into PVM blobs.
+//! This fails if any library address symbols are unknown at compile
+//! time (which is better known in Solidity as the so called "deploy
+//! time linking" feature). Since factory dependency symbols can be
+//! resolved only after the the final PVM blob linking step, missing
+//! libraries may further lead to unresolved factory dependencies.
