Label support in assembly #28

Closed jserv closed 6 years ago

jserv commented 7 years ago

Recently, @pakls contributed a series of conditional branch instructions which enables further translation from higher level languages to our virtual machine. However, lacking of labels prevents jump instructions from being efficiently used.

Thus, we expect that assembler can recognize labels as the indicators of open/close loop or deterministic location.

For reference, here is x86 labels reference: https://docs.oracle.com/cd/E19120-01/open.solaris/817-5477/esqaq/index.html

Symbolic labels should be easy to implement.
