NAME
fcml-asm - single-line assembler
SYNOPSIS
fcml-asm [-abs] [-sib] [-rex] [-all] [-gas] [-asa<size>] [-osa<size>] -m<size> -ip <address> <instruction>
DESCRIPTION
fcml-asm is a single-line assembler for Intel iAPx86, IA-32 and EM64T CPUs, and compatible CPUs from other manufacturers.
It displays all possible encodings of the given assembly-language instruction.
OPTIONS
fcml-asm accepts the following options:
- -abs
-
Prefer absolute memory addressing where possible. This is particularly useful in 64-bit mode, for RIP addressing.
- -sib
-
Prefer encoding using a SIB byte (scale * index + base).
- -rex
-
Use a REX prefix even if it is optional.
- -all
-
Return all possible forms of the instruction.
- -gas
-
Use GNU Assembler dialect (also known as AT&T). The Intel dialect is used by default.
- -asa<size>
-
Specify the size of the address size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).
- -osa<size>
-
Specify the size of the operand size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).
- -m<size>
-
Specify the addressing mode (16, 32 or 64).
- -ip <address>
-
Specify the instruction pointer address (IP, EIP or RIP).
