* API and data structures proposal for the SSA construction module * Polished API and implemented trivial functions * API more explicit, Variable now struct parameter * Sample test written to see how the API could be used * Implemented local value numbering for SSABuilder * Implemented SSA within a single Ebb * Unfinished unoptimized implementation for recursive use and seal * Working global value numbering The SSABuilder now create ebb args and modifies jump instructions accordingly * Updated doc and improved branch argument modifying. Removed instructions::branch_arguments and instructions::branch_argument_mut * SSA building: bugfix, asserts and new test case Missing a key optimization to remove cycles of Phi * SSA Building: small changes after code review Created helper function for seal_block (which now contains sanity checks) * Optimization: removed useless phis (ebb arguments) Using pessimistic assumption that when using a non-def variable in an unsealed block we create an ebb argument which is removed when sealing if we detect it as useless Using aliases to avoid rewriting variables * Changed the semantics of remove_ebb_arg and turned it into a proper API method * Adapted ssa branch to changes in the DFG API * Abandonned SparseMaps for EntityMaps, added named structure for headr block data. * Created skeletton for a Cretonne IL builder frontend * Frontend IL builder: first draft of implementation with example of instruction methods * Working basic implementation of the frontend Missing handling of function arguments and return values * Interaction with function signature, sample test, more checks * Test with function verifier, seal and fill sanity check * Implemented python script to generate ILBuilder methods * Added support for jump tables and stack slot * Major API overhaul * No longer generating rust through Python but implements InstBuilder * No longer parametrized by user's blocks but use regular `Ebb` * Reuse of allocated memory via distinction between ILBuilder and FunctionBuilder * Integrate changes from StackSlot * Improved error message * Added support for jump arguments supplied by the user * Added an ebb_args proxy method needed * Adapted to Entity_ref splitted into a new module * Better error messages and fixed tests * Added method to change jump destination * We whould be able to add unreachable code * Added inst_result proxy to frontend * Import support * Added optimization for SSA construction: If multiple predecessors but agree on value don't create EBB argument * Move unsafe and not write-only funcs apart, improved doc * Added proxy function for append_ebb_arg * Support for unreachable code and better layout of the Ebbs * Fixed a bug yielding an infinite loop in SSA construction * SSA predecessors lookup code refactoring * Fixed bug in unreachable definition * New sanity check and display debug function * Fixed bug in verifier and added is_pristine ;ethod for frontend * Extended set of characters printable in function names To be able to print names of functions in test suite * Fixes and improvements of SSA construction after code review * Bugfixes for frontend code simplification * On-the-fly critical edge splitting in case of br_table with jump arguments * No more dangling undefined values, now attached as EBB args * Bugfix: only split corresponding edges on demand, not all br_table edges * Added signature retrieval method * Bugfix for critical edge splitting not sealing the ebbs it created * Proper handling of SSA side effects by the frontend * Code refactoring: moving frontend and SSA to new crate * Frontend: small changes and bugfixes after code review
