for some reason, the version of 1.0.3 that was in the 4.4 lite tree
was modified to allow shops with two doors -- this violates the spirit
of the game. with this diff, we revert back to classic 1.0.3 behavior.
Delete IFM_IEEE80211_IBSS [ibss] and IFM_IEEE80211_IBSSMASTER [ibss-master]
from media options, since IEEE80211_ADHOC [adhoc] is already defined for
IBSS. Instead, [ibss] is assigned as an alias for IEEE80211_ADHOC.
Also note that adhoc can be used with flag0 to specify non-standard adhoc
demo mode in some drivers.
mediaopt adhoc 802.11 adhoc (IBSS) mode. IBSS creation is enabled
for cards which can create IBSS.
mediaopt adhoc,flag0 old lucent adhoc demo mode.
Note that [adhoc] media options for wi driver was used for adhoc demo mode,
which is NOW CHANGED.
* Declare arm_arch5 and arm_arch5e. Set arm_arch5 for if -mcpu=arm10tdmi,
-mcpu=arm1020t, -mcpu=xscale, -march=armv5, -march=armv5e, -march=armv5te.
Set arm_arch5e for -mcpu=xscale, -march=armv5e, -march=armv5te.
arm.md:
* Define the "clz" insn for arm_arch5.
* Define an "ffssi2" expander for arm_arch5 which uses "clz".
The GCC ChangeLog does not have a complete description to quote here,
so:
arm.c:
* arm_override_options(): Set arm_is_scale according to the the
-mcpu=xscale option. Set arm_constant_limit to 2 if arm_is_xscale.
* arm_adjust_cost(): If arm_is_xscale, account for stalls that can
occur due to shifted operands.
* arm_gen_load_multiple(): Account for the cost of ldm vs. ldr if
arm_is_xscale.
* arm_gen_store_multiple(): Likewise for stm vs. str.
arm.h:
* CONSTANT_ALIGNMENT(): Use a constant alignment factor of 2 if
arm_is_xscale.
* MOVE_RATIO: Set to 4 if arm_is_xscale.
arm.md:
* Add XScale scheduling parameters.
* Define a "shift" attribute (used by arm_adjust_cost()) and give it
to the appropriate operands on andsi_not_shiftsi_si, *shiftsi3,
*shiftsi3_compare0, *shiftsi3_compare0_scratch, *notsi_shiftsi,
*notsi_shiftsi_compare0, *not_shiftsi_compare0_scratch,
abssi2, *neg_abssi2, extendsidi2, *cmpsi_shiftsi, *cmpsi_shiftsi_swp,
*cmpsi_neg_shiftsi, *arith_shiftsi, *arith_shiftsi_compare0,
*arith_shiftsi_compare0_scratch, *sub_shiftsi, *sub_shiftsi_compare0,
*sub_shiftsi_compare0_scratch, *if_shift_move, *if_move_shift,
and *if_shift_shift.
