0004-Set-pseudos-only-once.patch


IRA and reload has special relationship with pseudos that are set only once. When such pseudos initialized with constants or instances that can be considered constant across the function, reload can rematerialize them instead of spilling or apply other optimizations.

This patch makes sure that we don't unnecessarily set same pseudo more than once.

OK to apply?

Thank you,
