- Subject: [MIPS]question about floating point conditional branch
Hello,
In mips.md, conditional branch insns are all set with the attribute
value 'branch'. But floating point instructions such as bc1f will
reserve falu unit instead of ialu. So there's a problem when you try
to describe pipeline for 'branch' insns. Define the ialu as the
reservation for all 'branch' insns? Is it OK?
