1. Introduction

liveanalysis is a liveness analysis pass built to be used with the SUIF2/ MachSUIF2 compiler infrastructure. This pass generates a textual representation for the liveness information in a given control-flow graph. It reports the live-in and live-out sets, while the kill and gen set can also be reported by setting the REPORT_KILL_GEN_SET compile-time switch.

This pass uses the cfa, bvd and machine libraries of Machine-SUIF. It works for the SUIFvm instruction set as well as other MachSUIF backends. The liveanalysis pass has been tested with MachSUIF 2.02.07.15.

2. File listing

The liveanalysis distribution includes the following files:

/liveanalysis Top-level directory
AUTHORS List of liveanalysis authors.
LICENSE The modified BSD license governs liveanalysis.
README.rst This file.
README.html HTML version of README.
README.pdf PDF version of README.
VERSION Current version of the project sources.
liveanalysis.cpp Implementation of the liveanalysis pass.
liveanalysis.h C++ header file containing declarations and prototypes for the above.
rst2docs.sh Bash script for generating the HTML and PDF versions of the documentation (README).
suif_main.cpp Entry point for building the standalone program do_liveanalysis that implements the pass.
suif_pass.cpp Define the SUIF pass built as the dynamically loadable library libliveanalysis.so.
suif_main.h C++ header file for the above.

3. Installation

Unpack the liveanalysis archive wherever you like, e.g. in $MACHSUIFHOME/cfa/liveanalysis. You don't need to modify anything in the Makefile, if you have a working MachSUIF 2 installation.

The program binary (do_liveanalysis) will be installed at $NCIHOME/bin and the shared library (libliveanalysis.so) at $NCIHOME/solib, where NCIHOME is the SUIF 2 top-level directory.

4. Usage details

The pass accepts an input file in CFG form to operate. Textual output is generated, written to stdout by default.

Usage synopsys:

$ do_liveanalysis test.cfg
