NONA(1) User Manuals NONA(1)NAMEnona - code selector description translator
SYNOPSISnona [ -c++ -v -debug -export -pprefix] specification-file
DESCRIPTION
Command nona translates code selector description (CS) which is
described in specification file into code for solving code selection
(tree matcher) and possibly other back-end tasks. The specification
file must have suffix `.nona' determined by CS builds cover of low
level internal representation (which must be a directed acyclic graph)
by the tree patterns with minimal cost on the first bottom up pass and
fulfills actions associated with the choiced tree patterns on the sec‐
ond bottom up pass.
Generated code consists of interface and implementation files having
the same names as one of specification file and correspondingly suf‐
fixes `.h' and `.c' (C code) or `.cpp' (C++ code).
Full documentation of OKA is in OKA User's manual.
OPTIONS
The options which are known for NONA are:
-c++ NONA generates C++ code instead of C code (default).
-v NONA outputs statistic information to standard output stream.
-debug NONA outputs debugging information during execution of function
`CS_find_cover' and `CS_traverse_cover' (see generated code).
-export
NONA generates macros defining identifiers of terminals as inte‐
ger constants and inclusion of their in the interface file.
Usually the user himself declares the identifiers in a C decla‐
rations section.
-pprefix
NONA generates names starting with prefix `prefix' instead of
`CS'.
