When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning: ../target/ppc/excp_helper.c: In function ‘powerpc_excp’: ../target/ppc/excp_helper.c:529:13: warning: this statement may fall through [-Wimplicit-fallthrough=] 529 | msr |= env->error_code; | ~~~~^~~~~~~~~~~~~~~~~~ ../target/ppc/excp_helper.c:530:5: note: here 530 | case POWERPC_EXCP_HDECR: /* Hypervisor decrementer exception */ | ^~~~ Add the corresponding "fall through" comment to fix it.
