[-asa<size>]
[-osa<size>]
-m<size>
-ip
<address>
<instruction>
Overview
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).
