From 105dd264de9a2fa7eee45eff897aa1d6171c1c4b Mon Sep 17 00:00:00 2001 From: Hans-Peter Nilsson Date: Sat, 23 Aug 2014 04:16:58 +0200 Subject: [PATCH] Fix frv-elf sim, default hardware to off. At 2974be626, frv-elf fails at the dv_sockser_install declaration in sim/frv/tconfig.in. But, with the trivial #include's added (see other sims tconfig.in, like cris or mn10300), it *still* fails building sim/frv/devices.c because of a missing UART_INCHAR_ADDR. I have no insight into what'd be a valid value, except that there's a definition in m32r, which was probably used as a template with frv not finished. Simulated hardware should not have been be enabled, and was indeed not enabled by default before 94c63d78f (2013-03-23), where it seems to have been enabled for no simulator-specific reason. Except dv-sockser.o wasn't enabled even then: sim/frv/config.in wasn't regenerated, so HAVE_DV_SOCKSER was never defined. Maybe people were fooled by this in sim/frv/Makefile.in at that time (these two lines were later deleted, in 73e76d20): CONFIG_DEVICES = dv-sockser.o CONFIG_DEVICES = (As it seems people have missed it before: the second line overrides the first...) I'm guessing these lines were part of the never-completed hardware-support. Commit 73e76d20 attempted to move the imagined dv-sockser.o from $(CONFIG_DEVICES) to $(frv_extra_objs) but missed that AC_SUBST would only affect @frv_extra_objs@ (not $(frv_extra_objs) per se) so nothing happened regarding sockser: dv-sockser.o was not compiled and HAVE_DV_SOCKSER was not defined. I'm removing the $(frv_extra_objs) too, to avoid confusion. The best action seems to be disabling all hardware support by default again until a specific sim maintainer finishes the work. Make check-sim for frv-elf shows no failures after this. sim/frv: * configure.ac: Default simulator hardware to off again.
