--- Comment #12 from Bernd Edlinger <edlinger at gcc dot gnu.org> ---
Aah, now I see (lto-wrapper.c):
if (parallel)
{
fprintf (mstream, "%s:\n\t@%s ", output_name, new_argv[0]);
for (j = 1; new_argv[j] != NULL; ++j)
fprintf (mstream, " '%s'", new_argv[j]);
fprintf (mstream, "\n");
/* If we are not preserving the ltrans input files then
truncate them as soon as we have processed it. This
reduces temporary disk-space usage. */
if (! save_temps)
fprintf (mstream, "\t@-touch -r %s %s.tem > /dev/null 2>&1 "
"&& mv %s.tem %s\n",
input_name, input_name, input_name, input_name);
}
else
{
char argsuffix[sizeof (DUMPBASE_SUFFIX) + 1];
if (save_temps)
snprintf (argsuffix, sizeof (DUMPBASE_SUFFIX),
"ltrans%u.ltrans_args", i);
fork_execute (new_argv[0], CONST_CAST (char **, new_argv),
true, save_temps ? argsuffix : NULL);
maybe_unlink (input_name);
}
IF parallel is true, the "ltrans%u.ltrans_args and the "ltrans%u.ltrans_args.0
is obviously not taken.
AND on my system I use a gnu-make
that does not always pass the jobserver file ids to the sub-makes.
Only when "$(MAKE)" is used.
I already thought about adding something like "#$(MAKE)" somewhere
to un-break that....
