--- Comment #2 from Soumya AR <soumyaa at gcc dot gnu.org> ---
Related: Using the C division operator with svfloat ICEs with g++ but not gcc.
Testcase:
#include <arm_sve.h>
svfloat16_t foo(svfloat16_t x) { return x / 4; }
Backtrace:
test2.cpp: In function ‘svfloat16_t foo(svfloat16_t)’:
test2.cpp:12:14: sorry, unimplemented: unexpected AST of kind

12 | return x / 4;
