            Bug ID: 110144
           Summary: cris-unknown-elf cross build fails with ICE if RTL
                    checking is enabled
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dimitar at gcc dot gnu.org
  Target Milestone: ---

I'm trying to cross build the current trunk:

  $ configure --target=3Dcris-unknown-elf --with-newlib --without-headers
--enable-languages=3Dc --disable-nls --disable-libssp --enable-checking=3Dy=
es,rtl

But the configure stage for libgcc fails with:

configure:3814:
/home/dinux/projects/pru/local-workspace/cris-gcc-build/./gcc/xgcc
-B/home/dinux/projects/pru/local-workspace/cris-gcc-build/./gcc/

Note that without "--enable-checking=3Dyes,rtl" the cross toolchain compila=
tion
is successful.=
