            Bug ID: 110778
           Summary: Alpha targets broken since r14-2587-gd8105b10fff951
                    (undefined reference to extended_count)
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jamborm at gcc dot gnu.org
                CC: ubizjak at gmail dot com
  Target Milestone: ---
              Host: x86_64-linux-gnu
            Target: alpha-linux-gnu

Since revision r14-2587-gd8105b10fff951 (combine: Change return type of
predicate functions from int to bool), very simple attempts to build a
cross-compiler for alpha targets fail.

I configure the compiler with:

  ../src/configure --target=alpha-linux-gnu --disable-bootstrap
--enable-languages=c,c++ --disable-multilib --enable-obsolete

and then run:

  make all-host CXXFLAGS="-O0 -g" CFLAGS="-O0 -g"

which fails with:

I have the simple/obvious fix to rtl.h.

    Fix alpha building

    The problem is after r14-2587-gd8105b10fff951, the definition of
    extended_count now takes a bool as its last argument but we only
    have a declaration for the version which takes an int as the last
    argument. This fixes the problem by changing the declaration to be
    a bool too.

    Committed as obvious after building a cross to alpha-linux-gnu.

    gcc/ChangeLog:

            PR target/110778
            * rtl.h (extended_count): Change last argument type
            to bool.
