[−][src]Module cranelift_codegen_meta::isa::x86::recipes
Encoding recipes for x86/x86_64.
Structs
| RecipeGroup | Helper data structure to create recipes and template recipes. It contains all the recipes and recipe templates that might be used in the encodings crate of this same directory. |
| Template | Previously called a TailRecipe in the Python meta language, this allows to create multiple variants of a single base EncodingRecipe (rex prefix, specialized w/rrr bits, different opcodes). It serves as a prototype of an EncodingRecipe, which is then used when actually creating Encodings, in encodings.rs. This is an idiosyncrasy of the x86 meta-language, and could be reconsidered later. |
Enums
| RexRecipeKind | Specifies how the REX prefix is emitted by a Recipe. |
Functions
| decode_opcodes | Given a sequence of opcode bytes, compute the recipe name prefix and encoding bits. |
| define | |
| replace_nonrex_constraints | Replaces constraints to a REX-prefixed register class by the equivalent non-REX register class. |
| replace_put_op | Given a snippet of Rust code (or None), replace the |
| supported_floatccs_predicate | Returns a predicate checking that the "cond" field of the instruction contains one of the directly supported floating point condition codes. |
| valid_scale | Return an instruction predicate that checks if |
