Tom de Vries 30c80d8833 [gdb/symtab] Fix wrong unit_type Dwarf Error
When running test-case gdb.dwarf2/fission-mix.exp using gcc-11 (and using the
tentative fix for PR27353 to get past that assertion failure), I run into:
...
(gdb) file fission-mix^M
Reading symbols from fission-mix...^M
Dwarf Error: wrong unit_type in compilation unit header \
  (is DW_UT_split_compile (0x05), should be DW_UT_type (0x02)) \
  [in module fission-mix2.dwo]^M
(No debugging symbols found in fission-mix)^M
...

The compilation unit that is complained about is:
...
Contents of the .debug_info.dwo section (loaded from fission-mix2.dwo):

  Compilation Unit @ offset 0x0:
   Length:        0x57 (32-bit)
   Version:       5
   Unit Type:     DW_UT_split_compile (5)
   Abbrev Offset: 0x0
   Pointer Size:  8
   DWO ID:        0x3e3930d3cc1805df
 <0><14>: Abbrev Number: 1 (DW_TAG_compile_unit)
...

And the dwarf error is triggered here in read_comp_unit_head:
...
        case DW_UT_split_compile:
          if (section_kind != rcuh_kind::COMPILE)
            error (_("Dwarf Error: wrong unit_type in compilation unit header "
                   "(is %s, should be %s) [in module %s]"),
                   dwarf_unit_type_name (cu_header->unit_type),
                   dwarf_unit_type_name (DW_UT_type), filename);
          break;
...
due to passing rcuh_kind::TYPE here in open_and_init_dwo_file:
...
      create_debug_type_hash_table (per_objfile, dwo_file.get (),
                                    &dwo_file->sections.info, dwo_file->tus,
                                    rcuh_kind::TYPE);
...

Fix this by changing the section_kind argument to create_debug_type_hash_table
to rcuh_kind::COMPILE, to reflect that we're passing &dwo_file->sections.info
rather than &dwo_file->sections.types.

Tested on x86_64-linux.

2021-02-25  Tom de Vries  <tdevries@suse.de>

	PR symtab/27354

		   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.
