From c938be8ad272a06bc0e91c4e718b61a0c5de400e Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Thu, 17 Apr 2014 11:53:22 -0700 Subject: [PATCH] i965/fs: Don't use brw_imm_* unnecessarily. Using brw_imm_* creates a source with file=HW_REG, and the scheduler inserts barrier dependencies when it sees HW_REG. None of these are hardware-registers in the sense that they're special and scheduling shouldn't touch them. A few of the modified cases already have HW_REGs for other sources, so it won't allow extra flexibility in some cases.
