gcc3 configuration for OpenBSD/m68k/ELF. Apparently, with the ELF toolchain
configuration, the wrong life analysis bug leading to removal of half the
code of ISDOT() in libc's fts.c fts_stat() no longer triggers.

Enable multilib to build -fpic and -fPIC versions of libgcc.a, in addition to
the fully static one. Update the compiler specs to allow for dynamic linking
of libraries and binaries.

Switch m88k ports to ELF.

Stop including other files in m88k/openbsd.h; instead specific the complete list
of files to include, in proper order, as tm_file at configure time. This

Stop including other files in m88k/openbsd.h; instead specific the complete list
of files to include, in proper order, as tm_file at configure time. This
requires openbsd.h to be split, as also encountered on other platforms, and will
make further work easier.
No functional change introduced.

Work-in-progress gcc 3.3.6 configuration for OpenBSD/vax.

Port the gcc 2.95 m88k fixes to the gcc 3 codebase, except for the function
frame setup and varargs handling, which need some more work at the moment.

Make C++ exception handling work on mips64.

ok miod@

On OpenBSD/hppa, not all space registers are equivalent, so don't set
MASK_NO_SPACE_REGS.

ok miod

Remove references to xm files that no longer exist. Taken from GCC 3.4.

ok brad@

Make exception handling work on alpha.

tested by naddy@, deanna@; ok brad@

Early bits for a 32-bit SuperH toolchain, currently for little-endian
systems only; more work is necessary in ld land.

zap sp64elf.h, get the only config part really used (PREFERRED_DEBUGGING_TYPE)
into openbsd64.h. Keep the other stuff in #if 0 for now.
okay miod@, brad@, pval@...

hppa64-unknown-openbsd build support; espie@ miod@ brad@ ok

get rid of i386elf.h which is an embedded platform include.
Get the only define we want, namely the debugger registers.
with this, i386 emits dwarf2 by default. Considering how well stabs
are tested

get rid of i386elf.h which is an embedded platform include.
Get the only define we want, namely the debugger registers.
with this, i386 emits dwarf2 by default. Considering how well stabs
are tested in recent gcc (not), this is a good thing.

Sleuthing work by kettenis@ and me.

Tried out by lots of people, including me, naddy, pvalchev, kettenis,
henning, hshoexer...

solve remaining conflicts

Add t-openbsd64 to handle some libgcc.a build issues (needed functions)
Change configuration to mips64 with default ABI = N64 (enhanced 64 bit ABI)
we also support the older O32 and N32 abi for build

Pick common code for trampoline mprotect() code. This did not work at all
on amd64 and was working on sparc64 by sheer luck (because we are not Solaris).

Copy arm/t-netbsd removing the shared libgcc pieces, suggested by espie

new file is needed to get define early enough for other headers, add
OpenBSD to the comments, adjust target code to be same as netbsd, now working.

Switch the arm compiler to generating strongarm code on openbsd.
add in statements to pass proper flags to assembler.

Split lib spec into pre-pthread/post-pthread.
Cosmetic change for us, will make merging with FSF easier.

Preliminary changes for ARM support on OpenBSD. "Can't hurt" espie@

hppa-openbsd configs; espie@ ok

Add x86_64-unknown-openbsd* target. Tested only as a cross-compiler.
