I checked the asm output between gcc 3.4 20030415 and 3.4 20030417.
Here is the diff for gengenrtl.c. It looks like the new gcc no longer
generates ldxmov/ltoff22x in certain cases. It doesn't look right to
me. Is that intentional?
BTW, there may be a small ldxmov/ltoff22x ld bug. Shouldn't we relax
ldxmov/ltoff22x after we finish all brl relaxation? I have a patch for
that.
