That has to be a kernel issue and not a GCC issue

Mystery solved: half the CPU cores report LWP as disabled, the other half as
enabled.
Both at boot, as seen with "grep -E '(core id|lwp)' /proc/cpuinfo" and
afterwards, using the CPUID instruction:

The problem persists in 8.2.0 and in current trunk. You need to run that
command a hundred of times or so, on a Piledriver, to replicate it:
for i in `seq 1 100`; do gcc -S t.c -march=native -v 2>&1 |
