Description Matheus Castanho 2022-01-26 13:46:03 UTC 
SUMMARY
valgrind issues a warning noting syscall number 387 is not implemented by valgrind on ppc64le when using upstream glibc. This seems to be map to the rseq syscall.

STEPS TO REPRODUCE
1. git clone git://sourceware.org/git/glibc.git
2. mkdir build && cd build
3. ../glibc/configure --prefix=/usr && make -j10 && make test t=elf/tst-valgrind-smoke

OBSERVED RESULT

--2953886-- WARNING: unhandled ppc64le-linux syscall: 387
--2953886-- You may be able to write your own handler.
--2953886-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--2953886-- Nevertheless we consider this a bug.  Please report
--2953886-- it at http://valgrind.org/support/bug_reports.html.

EXPECTED RESULT

No warning.

SOFTWARE/OS VERSIONS
