When compiling with LLVM and CONFIG_RUST is set, there exists the following objtool warning: rust/compiler_builtins.o: warning: objtool: __rust__unordsf2(): unexpected end of section .text.unlikely. objdump shows that the end of section .text.unlikely is an atomic instruction: amswap.w $zero, $ra, $zero According to the LoongArch Reference Manual, if the amswap.w atomic memory access instruction has the same register number as rd and rj, the execution will trigger an Instruction Non-defined Exception, so mark the above instruction as INSN_BUG type to fix the warning.
