            Bug ID: 110939
           Summary: 14.0 ICE at rtl.h:2297 while bootstrapping on
                    loongarch64
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: panchenghui at loongson dot cn
  Target Milestone: ---

since commit 7cdd0860949c6c3232e6cff1d7ca37bb5234074c, I get ICE at rtl.h:2297
when I try to bootstrap on loongarch64. 
I have seen the similar case in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110869 and try to build with the
latest commits in master branch but the problem still exists.

Configure:
../gcc/configure --prefix=/home/panchenghui/upstream-unmodded/build/install
--disable-libsanitizer --disable-gcov --disable-multilib

ICE output:
during RTL pass: combine
/home/panchenghui/upstream-unmodded/gcc/gcc/tree-cfgcleanup.cc: In function
