Bug ID: 471476
Summary: unhandled amd64-linux syscall: 441
Classification: Developer tools
Product: valgrind
Version: 3.21.0
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: cachegrind
Assignee: n...@valgrind.org
Reporter: ronnebaumfinan...@gmail.com

SUMMARY
***
unhandled amd64-linux syscall: 441
I received this warning message when running the commands below.
I ran the same command on a couple C programs after receiving the warning,
and they all output the same message show below.
The warning states that there is an unhandled amd64-linux syscall, specifying
441.
I'm not very inclined when it comes to hardware, but I am on an intel cpu, so
I'm
curious as to why there would be an amd syscall.
The programs that I ran the command on were compiled with the c89, c99, gcc,
and clang compilers.
All of the programs output the same warning message shown below.
***
STEPS TO REPRODUCE
1. valgrind --tool=cachegrind ls -l ./<program> (cmd source:
https://courses.cs.washington.edu/courses/cse326/05wi/valgrind-doc/cg_main.html)
I get the following output after running the command:
$ valgrind --tool=cachegrind ls -l ./<program>
WARNING: unhandled amd64-linux syscall: 441
You may be able to write your own handler.
Read the file README_MISSING_SYSCALL_OR_IOCTL.
Nevertheless we consider this a bug. Please report
it at http://valgrind.org/support/bug_reports.html.
