            Bug ID: 100269
           Summary: [12 Regression] i686 biarch compiler fails for Darwin
                    after r12-36.
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: iains at gcc dot gnu.org
  Target Milestone: ---

With the fix at r12-50-ga44895ce7ffbc26b4d765c40b5b346f8c9a9b762 applied,
bootstrap still fails for a 32b host with a 64b multilib.

$ ./gcc/xgcc -Bgcc -E -dM -m64 -xc /dev/null
cc1: sorry, unimplemented: 64-bit mode not compiled in

this is coming from i386-options.c:2050+

  if ((TARGET_64BIT_P (opts->x_ix86_isa_flags) != 0)
      != ((opts->x_ix86_isa_flags & OPTION_MASK_ISA_64BIT) != 0))
    sorry ("%i-bit mode not compiled in",
           (opts->x_ix86_isa_flags & OPTION_MASK_ISA_64BIT) ? 64 : 32);

unfortunately, it is not obvious to me what fix I need to make here.

Created attachment 50705
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50705&action=edit
patch under test

It doesn't seem that the rationale for the changes in r12-35/36 is captured
anywhere I could find - and the commit messages don't contain anything helpful.

This is my current guess at a more complete fix .. I tried it on i686-darwin9
(with an m64 multilib) and x86_64-darwin17 (with an m32 multilib) - but I
haven't tried it on a system with no multilib (e.g. x86_64-darwin20).
