I've just confirmed on focal that valgrind 1:3.15.0-1ubuntu9.1 fixes this issue.
I've also confirmed on bionic that valgrind 1:3.13.0-2ubuntu also fixes
this issue.
I used the following program to validate that valgrind doesn't crash
anymore:
cat test-sync.c
#define __SYNC(l) ".long (0x7c0004AC | ((" #l ") << 21))"
int
main ()
{
asm volatile(__SYNC(4) : : : "memory");
}
Thank you!
