mrnet's Introduction

Dyninst

Notes

Known issues should have open issues associated with them.
ARMv8 (64 bit) support for dynamic instrumentation is experimental and incomplete. For more details about current supported functionality refer to Dyninst Support for the ARMv8 (64 bit).

Build DyninstAPI and its subcomponents

Docker Containers

Containers are provided that can be used for Dyninst development (e.g., make changes to Dyninst and quickly rebuild it) or for development of your own tools (e.g., have a container ready to go with Dyninst). Links will be added here when the containers are pushed to the Dyninst associated package registries. Instructions for usage and building locally are provided in the docker directory.

Install with Spack

spack install dyninst

Build from source

Configure Dyninst with CMake

cmake /path/to/dyninst/source -DCMAKE_INSTALL_PREFIX=/path/to/installation
Build and install Dyninst in parallel

make install -jN

If this does not work for you, please refer to the Wiki for detailed instructions. If you encounter any errors, see the Building Dyninst or leave a GitHub issue.

Known Issues

Windows 64-bit mode is not yet supported
Windows rewriter mode is not yet supported
Exceptions in relocated code will not be caught
Linux rewriter mode for 32-bit, statically linked binaries does not support binaries with .plt, .rel, or .rela sections.
Callbacks at thread or process exit that stop the process will deadlock when a SIGSEGV occurs on a thread other than the main thread of a process
Stackwalker is fragile on Windows
Parsing a binary with no functions (typically a single object file) will crash at CodeObject destruction time.

mrnet's Issues

graph is not connected, found 0 potential roots

Anyone know what would cause this error:

graph is not connected, found 0 potential roots

This is using STAT as reported by a user in LLNL/STAT#46. I'm wondering if it is because of the ".bullx" in the FE hostname. Does MRNet think it is a fully qualified hostname? In this case, I don't think "bullx" is the domain name.

XPlat::Connect() does not handle EINTR properly

XPlat::Connect() when it encounters an EINTR error on the connect call will exit the function with -1 without any retries. However the EINTR error is likely recoverable by retrying the connect call again. Need to add EINTR to the list of errors which results in a connection retry.

Build fails on latest LLVM: ISO C++17 does not allow 'register' storage class specifier

@kupsch @bigtrak

I plan to add this to our CI testing at some point even though it doesn't use Dyninst. We should fix this and do a point release.

xplat_config.h and mrnet_config.h not installed with Lightweight MRNet

When building lightweight MRNet by itself (via "make lightweight-all") the files xplat_config.h and mrnet_config.h are not installed onto the system when Make Install is called. Thus if you are building MRNet with only lightweight support then you would not have these required headers installed on the system.

No way to specify the location of libexpat

There is no way to currently specify the location of libexpat. This is not a problem on most systems however on some systems a static version of libexpat may not be available which would result in the Cray version of MRNet failing to build properly.
