- Add a instruction value that contains the encoding, the address and a
flag to indicate if this instruction contains label references
- Add label value that contains an address
- Add reference value that contains offset, an absolute address and an
operand size
- define types for all value options in the union
- define accessor functions for all the values in the union
When two identifiers follow eachother it could be two instruction
mnemonics or one instruction mnemonic and one operand. To fix this
TOKEN_NEWLINE has been reintroduced as a semantic token. The grammar has
been changed to allow empty statements and every instruction and
directive has to end in a newline. Labels do not have to end in a
newline.
In addition to updating the grammar, the implementation of tokenlist,
ast and parser has been updated to reflect these changes.
- Exposes all errors in the header file so any user of the api can test
for the specific error conditions
- Mark all static error pointers as const
- Move generic errors into error.h
- Name all errors err_modulename_* for errors that belong to a specific
module and err_* for generic errors.
