            Bug ID: 112300
           Summary: Cross compiling to mipsisa64r2-sde-elf fails because
                    "HEAP_TRAMPOLINES_INIT was not declared in this scope"
                    since r14-4821-g28d8c680aaea46
           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: aburgess at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-linux-gnu
            Target: mipsisa64r2-sde-elf

Starting with r14-4821-g28d8c680aaea46, when I try to test that cross
compilation to target mipsisa64r2-sde-elf works by configuring gcc with:

$ ../src/configure --target=mipsisa64r2-sde-elf --disable-bootstrap
--enable-languages=c,c++ --disable-multilib  --enable-obsolete

and then building just the compiler with:

$ make -j64 all-host CXXFLAGS="-O0 -g" CFLAGS="-O0 -g"

The compilation fails with:

g++  -fno-PIE -c   -O0 -g   -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  
-fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing
