Rainer Orth e52a0f1bd9 Avoid short i386 register names on Solaris/x86 [PR25981]
This is the 32-bit companion to

	Remove unused ps_lgetLDT etc. on Solaris/x86 [PR25981]
        https://sourceware.org/pipermail/gdb-patches/2020-May/168713.html

A 32-bit-default gdb fails to compile with the updated <sys/regset.h>.
While it is also affected by the lack of a GS definition, which the
compantion patch above fixes, it also fails to compile i386-sol2-nat.c like
this

/vol/src/gnu/gdb/hg/master/git/gdb/i386-sol2-nat.c:181:3: error: 'EAX' was not declared in this scope
  181 |   EAX, ECX, EDX, EBX,
      |   ^~~

and several more.

While this could be fixed by either including <ucontext.h> here or
provding fallback definitions of the register macros, I chose to do what
the 64-bit-default code in the same file
(amd64_sol2_gregset32_reg_offset[]) does, namely just hardcode the
numeric values instead.  They are part of the ABI and thus guaranteed
not to change.

With this patch, a i386-pc-solaris2.11 configuration on master compiles
again, however, it doesn't work.  However, I could successfully test it
on the gdb-9 branch.

Compiling and testing proved to be messy, unfortunately:

* For one, Solaris <sys/procfs.h> and largefile support used to be
  mutually exclusive (fixed in Solaris 11.4 and Illumos), which was
  exacerbated by the fact that g++ predefines _FILE_OFFSET_BITS=64 since
  GCC 9.1.0.  For now I've worked around this by adding
  -U_FILE_OFFSET_BITS to CXXFLAGS and configuring with
  --disable-largefile.  I hope to clean this up in a future patch.

* gdb still defaults to startup-with-shell on.  However, /bin/bash is a
  64-bit executable which cannot be debugged by a 32-bit gdb.  I hacked
  around that part by pointing $SHELL at a 32-bit bash before running
  make check.

	PR build/25981
	* i386-sol2-nat.c [PR_MODEL_NATIVE != PR_MODEL_LP64] (regmap):
	Hardcode register numbers.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
