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:

Prefer absolute memory addressing where possible. This is particularly useful in 64-bit mode, for RIP addressing.
Prefer encoding using a SIB byte (scale * index + base).
Use a REX prefix even if it is optional.
Return all possible forms of the instruction.
Use GNU Assembler dialect (also known as AT&T). The Intel dialect is used by default.
Specify the size of the address size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).
Specify the size of the operand size attribute (16, 32 or 64 for respectively 16, 32 and 63 bits).
Specify the addressing mode (16, 32 or 64).
Specify the instruction pointer address (IP, EIP or RIP).
