How can I compile a set of ASM instructions in X86 Encoder Decoder (XED) syntax
I need to generate random ASM instructions. I found a really helpful XML file from UOPS which makes the random instruction generator program really simple. However, the XML file provides the instructions in Intel's X86 Encoder Decoder (XED) syntax,…

Intel XED (disassembler) -as [Address to start disassembling] option doesn't work
This one works fine yet provides all of the machine addresses as beginning at zero:
xed -i Halt7.obj
I really need the machine addresses to begin at their COFF object file offsets.
Here is what I have tried:
They give me the help message (list…

Intel XED: different function call addresses when decoding the same instruction
Consider the C code below:
#include
void greet(void){
printf("Hello!\n");
}
int main (){
greet();
return 0;
}
I compiled it with gcc to a 64-bit ELF called hello.
Then in my first experiment, I disassembled (decoded) the…

intel xed decoded instruction doesn't perfectly match the 8086 assembly code
I am playing a little bit with xed with in mind the purpose to write a little emulator of the intel 8086 and I want to use xed as the decoder. But when I am writing a little code in asm (compiled with nasm):
[CPU 8086]
mov al, 0x7F
xor bx, bx
xchg…
