difference between asm16 and asm files

difference between asm16 and asm files

[Tiger Liu(BJ-RD)]

Hi, experts:
I have a question about asm16 postfix and asm postfix.

Such as:
UefiCpuPkg\SecCore\Ia32\ResetVec.asm16

Why not use asm as postfix?

Thanks

Best wishes,

Asm16 is compiled to the binary file. Asm is compiled to the obj file, and linked into lib and EFI image. 

Now, asm16 is replaced by nasmb. Asm is replaced by nasm. If you check SecCore.inf, you will find ResetVec.asm16 is not used, and ResetVec.nasmb is used. I will send the patch to remove the unused ResetVec.asm16 to avoid the confuse.

Re: difference between asm16 and asm files

[Tiger Liu(BJ-RD)]

Hi, Liming:
Thanks for your reply!

I have another question:
Why not let sec code complied to obj file and linked to lib and EFI image?

I met a problem:
I tried to use IFDEF marco in an assembly inc file,  and this inc file would be included by ResetVec.asm16
But failed, it seemed asm 16 complier not recognize this marco exist.
If I changed ResetVec.asm16 to ResetVec.asm, and compiled again, the complier will recognize this marco exist.
But the last step failed, GenFds.exe seems search a binary file, and not found.

Thanks

Re: difference between asm16 and asm files

[Gao, Liming]

It is the first run code in X86 machine. It must be the raw execution code. 

I suggest you try nasmb file for your usage. 

Thanks

Re: difference between asm16 and asm files

[Tiger Liu(BJ-RD)]

Hi, Liming:
YES, its code need to be the raw execution code.
I mean:
1. We could use traditional asm code , compiled it, and use tools to translate them to the raw execution code.
Is there any difficulty to do this?

So, it would depreciate the asm16 or nasmb concept.

Thanks

Re: difference between asm16 and asm files

[Gao, Liming]

Tiger:
  Nasm compiler supports to generate 16bit raw code. User doesn't need to install the additional tool. And, the raw code is 16bit code. You need 16bit assembler. It is also nasm compiler. So, it is obvious to use nasm to directly do it.

Thanks
