Instruction Error Analysis using SHVAL

This repo is a fork of https://github.com/lam2mo/shval that performs:

  • Error evolution analysis per memory location.
  • Error evolution analysis per instruction.
  • Isolating error caused by functions.

Note: This fork disables MPFR shadow value analysis.

Instructions

Currently this project only works on x86_64 Linux.

Dependencies:

  • Intel Pin 3.2 (Tested version: 81205)

    Set the PIN_ROOT variable in the ./build.sh script.

    Copy pin_isa.H to PIN_ROOT/source/include/pin/

To build all tools, use the ./build.sh command in the tools directory. To run a tool, use a command similar to the following:

pin -t /path/to/obj-intel64/shval-native32.so -- /path/to/app

This assumes that the pin wrapper is in your PATH. Application parameters can be included at the end if necessary. In addition, most tools provide various command-line options to customize their runtime behavior. To see descriptions of each tool's options, run the tool without an app. These options must be specified after the tool library but before the -- separator.

Authors
