iburg -- A Code Generator Generator
|
||
|
|
|
||
|
|
iburg is a code-generator generator that uses dynamic programming at
|
||
|
|
compile time. It's described in
|
||
|
|
|
||
|
|
C. W. Fraser, D. R. Hanson and T. A. Proebsting,
|
||
|
|
Engineering a simple, efficient code generator generator,
|
||
|
|
ACM Letters on Prog. Languages and Systems 1, 3 (Sep. 1992), 213-226.

|
||
|
|
|
||
|
|
iburg is written in and generates ANSI C and thus must be compiled
|
||
|
|
with an ANSI C compiler and preprocessor, e.g., gcc or lcc. To compile
|
||
|
|
iburg, type "make". There should be no warnings or errors (except
|
||
|
|
perhaps in the system-dependent YACC skeleton). If you need to
|
||
|
|
customize the makefile, edit custom.mk, which is included in makefile.
|
||
|
|
The default custom.mk is empty.
|
||
|
|
|
||
|
|
sample.brg is from the paper in burg.ps, sample4.brg is from the paper
|
||
|
|
in iburg.ps, and sample5.brg is an example from a compilers course.
|
||
|
|
"make test" runs iburg on sample[45].brg and executes the resulting
|
||
|
|
programs. The output should be something like:
|
||
|
|
|
||
|
|
% make test
|
||
|
|
./iburg -I sample4.brg sample4.c; cc -o test4 sample4.c; ./test4
|
||
|
|
sample4.c
|
||
|
|
i = c + 4;
|
||
|
|
stmt: ASGNI(disp,reg)
|
||
|
|
disp: ADDRLP
|
||
|
|
reg: disp
|
||
|
|
disp: ADDI(reg,con)
|
||
|
|
reg: CVCI(INDIRC(disp))
|
||
|
|
disp: ADDRLP
|
||
|
|
con: CNSTI
|
||
|
|
./iburg -I sample5.brg sample5.c; cc -o test5 sample5.c; ./test5
|
||
|
|
sample5.c
|
||
|
|
stm: MOVE(MEM(loc),reg)
|
||
|
|
loc: NAME
|
||
|
|
reg: PLUS(MEM(loc),reg)
|
||
|
|
loc: PLUS(NAME,reg)
|
||
|
|
reg: MEM(loc)
|
||
|
|
loc: NAME
|
||
|
|
reg: con
|
||
|
|
con: CONST
|
||
|
|
%
|
||
|
|
|
||
|
|
To install iburg, copy it and its man page to the appropriate local
|
||
|
|
directories, e.g., on UNIX:
|
||
|
|
|
||
|
|
% cp iburg /usr/local
|
||
|
|
% cp iburg.1 /usr/local/man/man1
|
||
|
|
|
||
|
|
"make clobber" removes the executables and all derived files except
|
||
|
|
gram.c; "make clean" removes just object, core, and sample*.c files.
|
||
|
|
|
||
|
|
Mail bug reports along with the shortest input that exposes them to
|
||
|
|
drh@drhanson.net.
