For most instructions, the Solaris x86 assembler mnemonics are the same as the Intel or AMD mnemonics. However, the Solaris x86 mnemonics might appear to be different because the Solaris mnemonics are suffixed with a one-character modifier that specifies the size of the instruction operands. That...

This guide describes the basics of 32-bit x86 assembly language programming, covering a small but useful subset of the available instructions and assembler directives. There are several different assembly languages for generating x86 machine code. The one we will use in CS421 is the GNU Assembler...

control-transfer instructions. In 64-bit mode, instructions that use ModR/M addressing can use RIP-relative addressing. Without RIP-relative addressing, all ModR/M modes address memory relative to zero. RIP-relative addressing allows specific ModR/M modes to address memory relative to the 64-bit...
