Contribute sh64-elf.

2002-01-24  Alexandre Oliva  <aoliva@redhat.com>
* emulparams/shelf32.sh (STACK_ADDR): Define as formerly defined
in OTHER_RELOCATABLE_SECTIONS.
2002-01-18  Alexandre Oliva  <aoliva@redhat.com>
* emulparams/shelf32.sh (STACK_ADDR): Define.
(OTHER_RELOCATABLE_SECTIONS): Renamed to...
(OTHER_SECTIONS): this.	 Removed stack settings.
* emulparams/shelf64.sh (OTHER_RELOCATABLE_SECTIONS): Do not set.
(OTHER_SECTIONS): Reset after sourcing shelf32.sh.
2001-03-12  DJ Delorie	<dj@redhat.com>
* emultempl/sh64elf.em (sh64_elf_$_before_allocation): Disable
relaxing if any shmedia or mixed sections are found.
2001-03-07  DJ Delorie	<dj@redhat.com>
* emultempl/sh64elf.em (sh64_elf_before_allocation): Pass f to
einfo.	Gracefully decline to output to non-elf formats.
2001-03-06  Hans-Peter Nilsson	<hpn@redhat.com>
* emulparams/shelf64.sh (OTHER_RELOCATING_SECTIONS) <.stack>:
Default to _end aligned to next multiple of 0x40000, plus 0x40000.
* emulparams/shelf32.sh: Ditto.
2001-01-14  Hans-Peter Nilsson	<hpn@cygnus.com>
* emulparams/shelf32.sh (OTHER_RELOCATING_SECTIONS): Tweak
comment.
2001-01-10  Ben Elliston  <bje@redhat.com>
* emulparams/shelf32.sh (OTHER_RELOCATING_SECTIONS): Avoid
non-portable shell constructs. From Hans-Peter Nilsson.
2001-01-09  Hans-Peter Nilsson	<hpn@cygnus.com>
* emulparams/shelf64.sh (EXTRA_EM_FILE): Define empty.
* Makefile.am (eshelf64.c, eshlelf64.c, eshlelf32.c): Adjust
dependencies to the shell script include chain.
* Makefile.in: Regenerate.
2001-01-06  Hans-Peter Nilsson	<hpn@cygnus.com>
* emultempl/sh64elf.em: Update and tweak comments.
(sh64_elf_${EMULATION_NAME}_after_allocation): Always allocate and
make a .cranges section SEC_IN_MEMORY.
2000-12-30  Hans-Peter Nilsson	<hpn@cygnus.com>
* emultempl/sh64elf.em
(sh64_elf_${EMULATION_NAME}_before_allocation): Don't stop when
.cranges section found to be necessary; continue and set stored
section contents flags for sections with non-mixed contents.
Use a struct sh64_section_data container and sh64_elf_section_data
to store contents-type flags.
Remove unused update of "isec".
(sh64_elf_${EMULATION_NAME}_after_allocation): Only process
sections marked SHF_SH5_ISA32_MIXED.  Use sh64_elf_section_data to
access contents-type flags.  Assert that the associated container
is initialized.	 Use that container, not elf_gp_size, to hold size
of linker-generated cranges contents.
2000-12-18  Hans-Peter Nilsson	<hpn@cygnus.com>
* emultempl/sh64elf.em
(sh64_elf_${EMULATION_NAME}_before_allocation): Exit early if
there's already a .cranges section.  When section flag difference
is found, don't NULL-check cranges a second time.  Tweak comments.
(sh64_elf_${EMULATION_NAME}_after_allocation): Use size after
merging, not max size, as size of ld-generated .cranges contents.
Don't set ELF section flags in output section.	When checking for
needed .cranges descriptors, don't use a variable; compare
incoming ELF section flags directly to SHF_SH5_ISA32_MIXED.  Tweak
comments.
