768e321a24 Switch back to mnegl hi, mnegl lo, sbwc and prevent split_quadword_operands 
from using POST_INC in the case of negation.  Fix reversal of operands in
-Os use of ashq.

4fab8ae973 Fix addition of negative 64bit constants. Don't optimize the instructions 
too much otherwise we might use some that don't affect the carry bit.  Make
sure we are using paired instructions (add/adwc, sub/sbwc).

deb622ec5b Final step. Turn on generation of PIC code. Full release build builds and 
works.

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).
