I try one more importC case, get this error:
```sh
Error: undefined identifier `__builtin_unreachable`
```
any tips to fix this?

When I use importC to build a c library, there is a lot unused
symbol missing.
I try add `-L--gc-sections` to dmd to workaround this issue.
I also try `-L-dead_strip` on macOS, it work as expected.
I do some google, some one suggestion use with
`-ffunction-sections`, `-f fdata-sections`, d

This is the type defined from c code import by importC:
```c
struct A {
int count;
int[] i;
}
```
This kind data need to be init as const to avoid runtime cost,
and need to be done from D code.
how can I do this ?
To put code into D source, I can use "-i=package" to
automatically
I try use

If you only want to see the layout, you can use the following
command to dump it:
```
clang test.c -Xclang -fdump-record-layouts -c

File test.c could contain the following:

There is a case check will give wrong resutls:

That outputs `false`, because the symbol is not a compile-time

How can I get the function and type from importC? is there a
auto rename mechanism ?

The most pragmatic workaround is to add a typedef to the C code:

You don't have to change the code where the type is defined per
se, you just need to put it in any C file

typedef struct test_s

unsigned char _[64] __attribute__ ((aligned (sizeof (void
