> ROMCCFLAGS := -mcpu=p4 -fno-simplify-phi -O2 Without the line it fails to build. It builds with this line: ROMCCFLAGS += -fno-simplify-phi With this line it fails to allocate enough registers: ROMCCFLAGS := -fno-simplify-phi -O2 Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
