Thank you Jiong.
To help maintainers with this bug, here is a minimal test case which
reproduces the error (on a Rpi3 with Fedrora 31):
jullien@rpi64 $ cat print.c
#include <stdarg.h>
struct X { int _x; };
void
va_arg_bug(va_list ap) {
void *x = va_arg(ap, struct X *);
}
jullien@rpi64 $ tcc -c print.c
tcc: arm64-gen.c:257: arm64_type_size: Assertion `0' failed.
Aborted (core dumped)
>From arm64_type_size, type VT_STRUCT is indeed missing.
I’m going to push a patch and add new test case.

Subject: [Tinycc-devel] trouble shooting for arm64-gen.c
Hi guys,
I'm the fans to tinycc.
Today I compile the FFTW-3.3.8 by tcc. But it trigger the assert(0) in line
257 arm64-gen.c.
Then，I add "case VT_STRUCT: return 3;" int the tail of the switch block
curtly.
I wonder to know whether it is correct?
Best Regards!
Jiong
