Description
Write a program that implements pass 1 of an assembler for the language
described in the langdef.txt file.
Requirements:
1. use turnin to submit a tar file
2. the tar file must contain:
a. c/c++/python source program
b. makefile that builds a default target named p1 by simply
typing the command ‘make’
c. if the program is in python, it must contain the correct
#! first line and the makefile must copy it to a file named
p1 and p1 must be marked as executable using: chmod +x p1
3. p1 must run by typing:
./p1 FILENAME
where FILENAME is the name of a file containing a program in our
assembly language
4. p1 must print the symbol table to standard output in this format:
symbol location_in_decimal rel/abs
For example, for this input:
R0 EQU 0
LA 1,1
LABEL1 ST 1,I1
ST 1,I2
LABEL2 EQU 99
PINT 2,DATA
J LABEL3
DATA INTZ 12
END EQU DATA+12 # DATA can not be fwd ref
ORG DATA # DATA can not be fwd ref
I1 INTU 1
I2 INTU 1
ORG END # END can not be fwd ref
LABEL3 HALT
the program would print this output:
R0 0 abs
LABEL1 3 rel
LABEL2 99 abs
DATA 15 rel
END 27 rel
I1 15 rel
I2 16 rel
LABEL3 27 rel
