Re: [PATCH]: Define IRA_COVER_CLASSES for CRX target

Hello Jeff,

Thank you very much for your review and comments.

Don't you need a class with the HILO regs? From a quick look it appears that the crx considers the HILO registers allocatable (see destination operand for mulsidi3), so ISTM that the HILO regs need to appear in IRA_COVER_CLASSES.

Or am I misunderstanding something about the crx?

CRX target won't use the HILO registers for allocation, so its not required to add in IRA_COVER_CLASSES.

Thanks
Swami

Thanks. Installed.

Jeff
