Hello~

I'm getting this error on sparc64-linux-gnu when compiling gdb (commit
f0072f79e12 from git), in ctf-open.c:

gcc -O3 -mcpu=niagara4 -c libctf_la-ctf-open.c 
during RTL pass: expand
../../libctf/ctf-open.c: In function ‘ctf_bufopen_internal.part.0’:
../../libctf/ctf-open.c:1117:69: internal compiler error: in
expand_expr_real_2, at expr.c:9867
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.

As far as I know, compiling with -mcpu=niagara3 and -mcpu=niagara2 also fails
with the same error.
I'm using "gcc version 11.2.0 (GCC)". Attached is the preprocessed source of
the offending file.
