with bfd_elf_set_dt_needed_soname(). Fixes the "NEEDED crtend.o"
problem reported on tech-toolchain/current-users.
Problem spotted by Ryo HAYASAKA <ryoh@jaist.ac.jp>.
<string>" message if the stars were aligned incorrectly due to fast-and-
loose list handling.
The list handling code didn't discriminate between list nodes and list
heads, resulting in string comparisons using memory in the "list heads
by length" array as the target of the comparison; if the string being
handled was short enough and the pointers present in the list heads
array were just the right form the tool would get spurious matches and
exit with the above message.

change INITIALIZE_TRAMPOLINE() to use it, and apply the following
patch to it (which I have already submitted to GCC 3.3):
* config/i386/i386.c (x86_initialize_trampoline): Emit a call
to __enable_execute_stack with the address of the trampoline
if TRANSFER_FROM_TRAMPOLINE is defined.
Define a TRANSFER_FROM_TRAMPOLINE suitable for NetBSD targets, to enable
stack execution on target machines which can separate exec permissions for
a region:
* config/netbsd.h (NETBSD_ENABLE_EXECUTE_STACK): Define.
* config/alpha/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Define
as NETBSD_ENABLE_EXECUTE_STACK.
* config/i386/netbsd-elf.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
* config/i386/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
* config/sparc/netbsd-elf-common.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
* config/sparc/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
(A similar patch will be submitted to GCC 3.3.)

tramp, not addr, to pass the trampoline address to

Otherwise, incorrect behavior would result if the trampoline happend
to stradle a page boundary.
we saved the GOT pointer register.
Note: This is already fixed in the GCC 3 sources, but GCC 3 uses a different
condition to determine whether to save and restore the register, so the patch
cannot be the same.

* Rename TARGET_ATPCS_STACK_ALIGN to TARGET_ATPCS.
* Move APTCS aggregate return rules to arm_return_in_memory(), conditional
on TARGET_ATPCS, and make it also return true for variable-sized aggregates.
* 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.
treated like -march=armv4t, but which generate __ARM_ARCH_5__,
__ARM_ARCH_5T__, and __ARM_ARCH_5TE__ defines, respecitively.
* Add -mcpu=xscale, which is internally treated like -mcpu=strongarm,
but which generates __ARM_ARCH_5TE__ and __XSCALE__ defines.
These command-line options and definitions are consistent with gcc 3.x,
and allow NetBSD Makefiles to use them in a forward-compatible way, and
also give hand-tuned source code (e.g. assembly) a chance of tuning for
XScale.
reasons:
1) There is already a destructor that does this. The atexit() is superfluous.
2) If libstdc++ is loaded dynamically by dlopen() and then is removed by
dlclose(), the pointer is no longer valid and the program would core dump
at exit() time. (This caused xmms to core dump at exit when xmms-sid was
installed, for example.)
also comment out continuation lines. Fixes Linux->NetBSD
cross-gdb when built using NetBSD's make(1) (a'la build.sh -t).

compare_addsi2_op0 & compare_addsi2_op1. From the comment I've just
inserted:
;; XXX RWE: The reload pass of GCC-2.95 makes a mess of these if one of the
;; arguments is, or is directly derived from, an eliminable register. In
;; that case reload will substitue into the PLUS and then canonicalize it
;; without regard to the the match_dup parts. Since these are rare, I've
;; disabled them for now, but they should be OK in 3.x (which manages the
;; substitution without canonicalization.

Enable -msoft-quad-float as the default moving forward. A complete build with
this compiler produces no errors and passes known regressions problems (awk,
etc).
XXX - -mhard-quad-float no longer will generate code correctly (internal
compiler problems). This is the case all the way to gcc-current so it's not
an easy fix at the moment but no one should be using hard quad math anyways.
If one doesn't subtract the stack bias back off %fp before attempting
to access variables stored relative to %fp the wrong address is picked up for
all locals and args. So, calls to the FRAME_LOCALS_ADDRESS or
FRAME_ARGS_ADDRESS macros need a function for sparc64 specific cases.
Provide a function to check for bias's addresses and fix them up.

set the C(arry) bit appropriately. All other leave it in an indeterminate

of branches that use the C bit to use OUTPUT_JUMP so that if CC_NO_OVERFLOW is
set, branches that would normally use the C bit use opcodes that don't use the
C bit (jgtru -> jneq && jlssu -> jeql). Delete the cmpdi pattern.
