I am trying to assemble some 64-bit code and the assembling fails on the line:
addq $0xffffff7fc0005000, %rax
with the error:
Error operand type mismatch for `add'
The first operand is a 64-bit value and the latter a register which should assemble fine. This instruction is preceded by a .code64
pseudo-op. I am assembling with
x86_64-elf-as test.s -o test.o --64
As for the assembler itself, when called with --version
it returns:
