C-referenceable names, i.e. "link sets") that happens with explicit
LMAs in the linker script:
* As orphans are sorted after sections, the effective
size of the section is changed. Record a size ajustment
for each orphan that is sorted after the section.
...and for sections which have an explicit load address expression:
* The first time an orphan is sorted after a section,
copy the load_base expression to the orphan, adding
the _unadjusted_ size of the parent section. We need
to use the unadjusted size because by the time the
expression can be folded, all of the orphan size
adjustments will have accumulated, resulting in misplacing
the orphan.
* For each subsequent orphan sorted after a section,
set the load_base of the orphan to the load address
of the previous orphan plus the size of the previous
orphan (actually, the unadjusted size, but for orphans,
size and unadjusted size are always equal).

specs, respectively.
Corresponding GCC ChangeLog entry:
2002-11-19 Jason Thorpe <thorpej@wasabisystems.com>
* gcc.c (The Specs Language): Document spec functions.
(static_spec_functions, lookup_spec_function)
(eval_spec_function, handle_spec_function)
(if_exists_spec_function, alloc_args): New.
(execute): Abort if processing_spec_function is true.
(do_spec_1): Hand off spec to handle_spec_function if %:
is encountered. If processing_spec_function is true,
end any pending argument when the end of the string is reached.
(main): Use alloc_args to allocate the initial argument vector.
* gcc.h (struct spec_function): New.
(lang_specific_spec_functions): New extern.
* config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s).
(ENDFILE_SPEC): Add if-exists(crtn%O%s).
* config/alpha/netbsd.h (ENDFILE_SPEC): Likewise.
unless one of the following flags are passed to the compiler:
-mno-abicalls
-fno-pic
-fno-PIC
Based on the following change in gcc-current:
2002-09-22 Jason Thorpe <thorpej@wasabisystems.com>
* config/mips/netbsd.h (SUBTARGET_ASM_SPEC): Always pass -KPIC
unless -fno-pic or -fno-PIC is specified.
The -mno-abicalls handling is new to this patch, and will be checked
into gcc-current shortly.
2002-09-28 Matt Thomas <matt@3am-software.com>
Jason Thorpe <thorpej@wasabisystems.com>
* config/tc-vax.c (md_estimate_size_before_relax): Only try to
convert undefined references to GOT32/PLT32 if PIC code is
requested. Fix comment.
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.)
2002-10-17 Jason Thorpe <thorpej@wasabisystems.com>
* config/alpha/alpha.c (alpha_initialize_trampoline): Use
tramp, not addr, to pass the trampoline address to
__enable_execute_stack.
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.
large functions for ARMv4):
Fri Nov 12 13:31:54 1999 Bernd Schmidt <bernds@cygnus.co.uk>
* config/arm/arm.h (LEGITIMIZE_RELOAD_ADDRESS): Treat QImode
addresses the same way GO_IF_LEGITIMATE_INDEX does.
