LWTools: lwasm/pragma.c annotate

annotate lwasm/pragma.c @ 473:8181ddd707f1

Add "nooutput" pragma Add the "nooutput" pragma which causes assembly to proceed as normal for code with the exception that no output is generated for any instructions under this pragma. The current address is increased as usual and the symbol table is still constructed. However, no actual output is generated for lines operating under this pragma.
