[gem5-users] Generate binary for new added instruction

[Abhishek Singh]

Hello Everyone,

I have added new instruction in x86 isa of gem5. I wanted to test it using
(modified) binary. As new instruction are not identified by general gcc/g++
complier on host x86 machine. I am unable to get binary.
I am using SE mode of gem5. Is there a way to run new instruction using asm
inline function, and generate new binary to run the application on gem5?

Thanks,
Abhishek

Try GCC __asm__ with raw bytes via .inst, e.g.
https://github.com/torvalds/linux/blob/94710cac0ef4ee177a63b5227664b38c95bbf703/arch/arm/include/asm/barrier.h#L23
