Typedef Documentation

mir_bitfield_field_t

typedef struct mir_bitfield_field mir_bitfield_field_t

A bitfield's field declaration.

mir_bitfield_spec_t

typedef struct mir_bitfield_spec mir_bitfield_spec_t

A bitfield or bitfield's field declaration.

Examples:

1. Reg{arg1}
2. Opcode { opcode = 0x11, reg = arg1 }

In the second example, the opcode = 0x11 and reg = arg1 are represented with this struct too, in the spec list of the Opcode{} specification.

mir_bitfield_spec_type_t

typedef enum mir_bitfield_spec_type mir_bitfield_spec_type_t

A bitfield spec type.

It's specify the type of the specification for bitfield's value.

mir_bitfield_t

typedef struct mir_bitfield mir_bitfield_t

A bitfield declaration.

mir_inst_param_t

typedef struct mir_inst_param mir_inst_param_t

An instruction's parameter.

Example: inst not[32](arg: register[32])

mir_inst_t

typedef struct mir_inst mir_inst_t

Instruction declaration.

mir_register_t

typedef struct mir_register mir_register_t

Register declaration.

mir_t

typedef struct mir mir_t

Mya in-memory intermediate representation.

mir_type_t

typedef enum mir_type mir_type_t

Enumeration Type Documentation

mir_bitfield_spec_type

enum mir_bitfield_spec_type

A bitfield spec type.

It's specify the type of the specification for bitfield's value.

Enumerator
FT_FIELDS	Bitfied spec value has a body with a list of fields. Example: Opcode{ opcode = 0x1, reg = arg1 } On this type, spec is the used value with a list of bitfield spec's fields.
FT_IDENTIFIER	Bitfield spec value is a identifier. Example: Reg{arg2} On this type, identifier is the used value.
FT_LITERAL	Bitfield spec value is a literal value. Example: Reg{4} On this type, value is the used value.
FT_SPEC	Bitfield spec value is a bitfield spec. Example: reg = Reg{2} On this type, spec is the used value with an unique bitfield spec.
