*	Switch addpc to use pc-offset instead of immediate operand	Bobby Bingham	2017-01-15	2	-2/+5
\| \| \| \| \|	This makes more sense, as the argument is really a signed offset from the program counter.
*	nqasm: Reformat nop grammar	Bobby Bingham	2017-01-15	1	-2/+1

*	nqasm: Handle pc offset arguments	Bobby Bingham	2017-01-15	1	-14/+20
\|
*	nqasm: Rename arglist non-terminals to a_*	Bobby Bingham	2017-01-15	1	-39/+46
\| \| \| \| \|	This will allow differentiation between pcoff (a single argument) and a_pcoff (an argument list consisting of only a pcoff argument).
*	nqasm: Handle immediate arguments	Bobby Bingham	2017-01-15	2	-6/+41

*	nqasm: Handle register and register indirect arguments	Bobby Bingham	2017-01-15	5	-53/+76

*	nqasm: Improve parsing at end of file	Bobby Bingham	2017-01-15	2	-4/+6
\| \| \| \| \| \| \| \| \|	Bison's implicit $accept rule ends with the END token. The fact that input could also end with END (via the line non-terminal) resulted in a shift reduce conflict. We resolve the conflict by modifying the lexer so that if it encounters end of file partway through a line, it produces a final EOL token before EOF.
*	Add gitignore	Bobby Bingham	2017-01-15	1	-0/+7
\|
*	nqasm: Initial stab at a lexer and parser	Bobby Bingham	2017-01-15	5	-0/+278
\| \| \| \| \|	So far, this only understands instructions, but no operands or labels. It doesn't handle bad input gracefully. It's just enough to test the basics.
*	Add table of instructions and their encodings	Bobby Bingham	2017-01-15	2	-0/+104
