Fixes "internal compiler error: in do_SUBST" on compiling
floating point ops with -msoft-float or -m68010 on LP64 hosts,
and may also close PR toolchain/38359.  Tested on alpha.

29c39f7ad5 Add -lc when -shared so that all shared libraries built by the compiler 
have a dependency to -lc. To avoid adding that dependency in -lc and -lgcc*
we add -nostdlib to the compile rules.

95c5c2aebe Defer wide int L/LL suffix choice in insn-*.c until we compile for 
host using correct set of HOST_WIDE_INT* defines.  Fixes compilation
of native sh3 gcc on 64-bit build machines.

Background and details in NetBSD PR 34549 and GCC bug 32497.
Tested by Joerg and myself.

Approved by "looks ok, but let some other guy decide" from ~all of our
gcc folks.

c1e4ee94be Fix kernel profiling on HPPA. 
- stop gcc emitting stuff that HPUX requires
- don't use splhigh() in MCOUNT_ENTER as a call to _mcount will be
  generated at the moment. Disable interrupts in hardware instead.
- Fix _PROF_PROLOGUE to save/restore all the register args when calling
  _mcount.
- Fixup LEAF_ENTRY to dtrt (I think) in the GPROF case.
- Provide LEAF_ENTRY_NOPROFILE and sprinkle its use where i) profiling
  causes problems, e.g. trap handlers, and ii) where it just doesn't
  make sense, e.g. start.

bd8f620dfb Modify the gcc configure script to allow override of the "target libc 
has ssp functions built-in" test via the TARGET_LIBC_PROVIDES_SSP environment
variable, to allow us to configure a cross-compiler appropriately without
having to try to find out by looking in the target's source directory.

Tweak our build to tell gcc that the ssp bits are now in libc.

The native compiler appears to already think that the ssp bits
live in libc, so no change appears to be needed there.

The autoconf-generated configure script will be committed separately shortly.

dec8719ee4 For nonimmediate operands of SImode, don't use "g" anymore, use "nrmT" instead. 
"g" matches just about anything including SYMBOL_REF, CONST, LABEL_REF which
should not be operands for most instructions in PIC mode.  (movsi can handle
then and addsi3 can handle them in a few limited cases).

aa3062f197 Step 2. Produces PIC code but doesn't satisfies the constraints needed 
by userland.  (external symbols can still be indirected and relocs for
symbol + offset are emitted).

f775e4410d Enable new quadmove code. Only use mova[lq] instead of ashl when 
!optimize_size.  When optimize_size is on, try to use ashl if possible
if setting a 6bit unsigned quantity in the word.

58ad121651 Step 1 of getting gcc to generate VAX PIC code again. These steps are being 
committed in "smallish" steps.  This step incorporates the switch to MEM_P,
REG_P, and CONST_INT_P.  Use bool/true/false where appropriate.  PRINT_OPERAND
moves from being a large macro in vax.h print_operand in vax.c.  Fix rtx cost
for a constant of 0.  This eliminates unneeded moves when setting to 0 would
be fine.

Lastly, include completely new (on by default) code for DImode move, addition,
and subtract.  This code is significantly faster and smaller that what existed
before.

e43d142e40 Steal code from tc-sparc.[ch] to implement a vax specific "cons" routine. 
Add a %pcrel{32,16,8}(exp) special which emit a PC32 relocation to exp.
This will be used by the gcc dwarf code to generic .eh_frame sections which
are read-only and can be put in the text PT_LOAD.

02f41de9c1 Don't emit PLT entries for PC32 entries not in a code section. 
Don't emit PC32 relocations in shared libraries if the relocation is not in
a section with the CODE attribute.  (This is for DWARF2).
