That does not work because then all LTO test cases fail.
lto-wrapper.c has:
...
int debug; /* true if -save-temps. */
...
static void
maybe_unlink_file (const char *file)
{
if (! debug)
{
if (unlink_if_ordinary (file)
&& errno != ENOENT)
fatal_perror ("deleting LTRANS file %s", file);
}
else
fprintf (stderr, "[Leaving LTRANS %s]\n", file);
}
and the additional "[Leave LTRANS..." output makes all LTO tests fail.
Even with -save-temps there are non-reproduceable file names (here
from mingw):
[Leaving LTRANS C:\Temp\ccw1rUwh.args]
[Leaving LTRANS ab.elf.ltrans.out]
[Leaving LTRANS C:\Temp\ccJbGYVI.args]
[Leaving LTRANS ab.elf.ltrans0.o]
