------- Comment #19 from jakub at gcc dot gnu dot org 2008-10-24 18:09 -------
This hunk in df-scan.c confuses me:
/* These registers are live everywhere. */
if (!reload_completed)
{
#ifdef EH_USES
/* The ia-64, the only machine that uses this, does not define these
until after reload. */
for (i = 0; i < FIRST_PSEUDO_REGISTER; i++)
if (EH_USES (i))
{
bitmap_set_bit (entry_block_defs, i);
}
#endif
Indeed, ia64 is the only port that defines EH_USES ever to non-zero value, and
only if reload_completed. So this is a nice nop, but supposedly just changing
the guarding condition to if (reload_completed) could fix this up.
