Title: mov r64,imm64
Post by: mineiro on August 01, 2016, 10:26:06 PM

How can I write this?
mov rax,0123456789abcdefh

I'm receiving "Error A2235: Constant value too large: 123456789ABCDEFh"

Using other assembler I'm getting this:
   0:   48 b8 ef cd ab 89 67    movabs rax,0x123456789abcdef
   7:   45 23 01

Thanks

  mov rax,123456789ABCDEFh
00007FF6729210F1 48 B8 EF CD AB 89 67 45 23 01 mov         rax,123456789ABCDEFh
This is what I get with HJWasm

Thanks for answering sir habran
well, I'm getting this result using HJWasm. Maybe my version is older or because is that I'm trying to generate elf file, follows the code.

Code: [Select]

;hjwasm -elf64 -Fo=test.o test.hjwasm
.x64
.code
public _start
_start:
mov rax,0123456789abcdefh
end
