Feature #1672
closedEasy interface for Aspectator
0%
Description
As far as I recall, our Aspectator tool has a tricky and somewhat inconvenient interface. Ideally, it should be called like this:
aspectator first.aspect second.aspect ... last.aspect -I /path/ ... file1.c file2.c ... (usual C compiler options)
And the result should appear in the output -o file (or in a.out), all temporary directories being created automatically in the proper places. Such a simple interface is required for:
- publishing our tools to the external users
- for us, to make experimentation with verifiers easier (i.e. without building comprehensive rule models).

This task became more important since we began to use CIF more extensively. For instance, in #2462 it's used to execute information requests to get argument signatures. #2959 also needs CIF to extract information on driver structures and callbacks registration. At last it will be very well if CIF will have good interface before publishing it (#2159).

- Aspectator is a tool that extends GCC with implementation of aspect-oriented programming for the C programming language.
- CIF is interface for Aspectator intended for high-level and convenient manipulations of instrumentation stages (this interface can be used by Rule Instrumentor, Rerouter and Driver Environment Generator, for instance).
As for repository and installation, CIF is already named correctly (cif) while for Aspectator it's used something like aspectator-core. I'm going to fix names while resolving #2227.

Here is current version of help for CIF (I guess that it answers the most of questions how to use it):
NAME
./cif: instruments a file using an aspect and options
specified.
SYNOPSIS
./cif [option...] [-- options_for_aspectator]
OPTIONS
--aspect <file>
Aspect <file> to be used for instrumentation.
--aspect-preprocessing-opts <string>
Options specified by means of <string> will be passed as is at
'aspect preprocessing' stage.
--back-end <back-end>
Use specified back-end to produce output at 'comilation' stage. Following
back-ends available: 'bin', 'asm', 'obj' and 'src'.
--aspectator <bin>
<bin> is executable to be used as aspectator during instrumentation.
--compilation-opts <string>
Options specified by means of <string> will be passed as is at 'compilation'
stage.
--debug <level>
Debug <level> may be 'QUIET', 'WARNING', 'NORMAL', 'INFO', 'DEBUG', 'TRACE'
or 'ALL'. Each following level includes all messages of levels before it.
--file-preparation-opts <string>
Options specified by means of <string> will be passed as is at
'file preparation' stage.
--general-opts <string>
Options specified by means of <string> will be passed as is at all stages.
-h, --help
Print this help and exit with a syntax error.
-c, --in <file>
Input <file> to be instrumented.
--instrumentation-opts <string>
Options specified by means of <string> will be passed as is at
'instrumentation' stage.
--keep
Keep intermediate files.
--keep-prepared-file
Keep just prepared intermediate file. This may be required because of
preprocessed file refers to the given file instead of the original one.
--macro-instrumentation-opts <string>
Options specified by means of <string> will be passed as is at
'macro instrumentation' stage.
-o, --out <file>
Specified back-end will place output to <file> if 'compilation' stage will
be performed. Intermediate files are placed near output file.
--stage <stage>
<stage> may be one of 'aspect preprocessing', 'file preparation', 'macro
instrumentation', 'instrumentation', 'compilation'. Each following stage
includes all previous stages. 'Compilation' stage is used by default.
options_for_aspectator
This is list of options that will be passed to aspectator as is. Note that
these options are processed by your interpreter before passing to CIF, so
don't forget about proper escaping.
ENVIRONMENT VARIABLES
LDV_ASPECTATOR
Optional environment variable that specifies aspectator to be used during
instrumentation. This option has more priority then using default and
specified by means of --aspectator aspectator.
Script itself is available in feature-1672 branch.

I guess that CIF is rather well interface for Aspectator. As one can notice CIF can be used instead of compiler in building any applications. But to do this one should specify required options: -in, --out, options after -, --aspect, --aspectator, --back-end.
