* Start adding the load_complex and store_complex instructions. N.b.: The text format is not correct yet. Requires changes to the lexer and parser. I'm not sure why I needed to change the RuntimeError to Exception yet. Will fix. * Get first few encodings of load_complex working. Still needs var args type checking. * Clean up ModRM helper functions in binemit. * Implement 32-bit displace for load_complex * Use encoding helpers instead of doing them all by hand * Initial implementation of store_complex * Parse value list for load/store_complex with + as delimiter. Looks nice. * Add sign/zero-extension and size variants for load_complex. * Add size variants of store_complex. * Add asm helper lines to load/store complex bin tests. * Example of length-checking the instruction ValueList for an encoding. Extremely questionable implementation. * Fix Python linting issues * First draft of postopt pass to fold adds and loads into load_complex. Just simple loads for now. * Optimization pass now works with all types of loads. * Add store+add -> store_complex to postopt pass * Put complex address optimization behind ISA flag. * Add load/store complex for f32 and f64 * Fixes changes to lexer that broke NaN parsing. Abstracts away the repeated checks for whether or not the characters following a + or - are going to be parsed as a number or not. * Fix formatting issues * Fix register restrictions for complex addresses. * Encoding tests for x86-32. * Add documentation for newly added instructions, recipes, and cdsl changes. * Fix python formatting again * Apply value-list length predicates to all LoadComplex and StoreComplex instructions. * Add predicate types to new encoding helpers for mypy. * Import FieldPredicate to satisfy mypy. * Add and fix some "asm" strings in the encoding tests. * Line-up 'bin' comments in x86/binary64 test * Test parsing of offset-less store_complex instruction. * 'sNaN' not 'sNan' * Bounds check the lookup for polymorphic typevar operand. * Fix encodings for istore16_complex.
This crate contains the core Cretonne code generator. It translates code from an intermediate representation into executable machine code.
