gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [21/21]

Define separate instruction patterns for extzv for the cases where the fiel
d width and offset happen to be a multiple of a byte or word.

If in PIC mode, and the source operand to extzv is a memory
reference, and the address of the memory location is an external
symbol, load the address into a temporary register before expanding
the instruction.

Adjust the constraints to the zero_extract instruction pattern to
disallow indexed source operands, as the VAX extzv instruction
computes offsets based on the size of a byte (not a word or a
longword)

use the extzv instruction pattern for logical shifts right

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [7/21]

Mark the output operands of the 'sbcdi3' instruction pattern as being
written before the instruction has finished using the input operands.

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [2/21]

Add a special case to the zero_extract instruction to handle the case
where 32 bits are requested (i.e. the entire word). When printing a mask
operand, avoid generating values that might overflow a 32 bit word.

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [1/21]

Save %r2..%r5 in the prologue of functions which call __builtin_eh_return().
Implement the eh_return() instruction. Ensure that the CFA is correct

Remove directory, requested by mrg in ticket #123:

	external/gpl3/gcc.old		(remove)

This directory is not used on this branch.

merge GCC 10.4 into gcc.old.

initial import of GCC 10 sources into "gcc.old".

merge GCC 9.3 into gcc.old.

second attempt in the right place:

import of GCC 9 into gcc.old in preparation for GCC 10.

merge GCC 8.4 into gcc.old.

initial GCC 8.4 -> gcc.old import.

Mostly merge changes from HEAD upto 20200411

merge gcc 7.4 into gcc.old part 3 (last?)

import GCC 7.4 as gcc.old

delete GCC 6.5.  every platform has been on GCC 7 for a while now.

Sync with HEAD

Sync with HEAD

Resolve a couple of conflicts (result of the uimin/uimax changes)

merge GCC 6.4 into gcc.old.

import GCC 6.4 srcs into gcc.old in preparation for GCC 7.x.

these are netbsd GCC srcs from 20180801.

merge GCC 5.4 into gcc.old.

import the GCC 5.4 srcs from -current as gcc.old in preparation for GCC 6.

Sync with HEAD

Remove gcc.old now it is no longer used.

re-merge GCC 4.8.5 (part 1)

import GCC 4.8.5 as gcc.old, in prepartion to update GCC.

delete gcc 4.5, as requested by mrg in ticket #674

delete GCC 4.5.

Rebase to HEAD as of a few days ago.

sync with head.

import the -current GCC 4.5 sources as gcc.old in preparation for
upgrading the normal GCC to 4.8.

this tree has had ChangeLog entries removed, as well as all the
other components we delete, and "only" weighs in around 140MB now.
