ATLAS Assembly Homepage

This page consolidates some assembly references I've found handy in my ATLAS programming. You may also find the ATLAS architecture page useful.

Basic assembly starting points:

register & stack frame usage for various assemblies directly supported by ATLAS.
Gnu assembly manual.
- x86 assembly from the manual (including unix (AT&T)/MASM differences).
IBM's introduction to PowerPC assembly.
Linux assembly page.

ISA references:

ABI references:

System V ABI for x86
System V ABI for AMD64 (NOTE: Intel calls AMD64 EM64T, and it is also known as x86-64).
System V ABI for PowerPC (Unix/Linux)
- 64 Bit Supplement
MIPS ABIs are numerous and confusing:
- System V ABI for 32-bit MIPS describes original MIPS32 (MIPS1 and MIPS2) platform. Uses only 16 fp regs, integer regs are always 32 bits.
- Pages 23-29 amend 32-bit ABI for 64 bits. This is full 64 bit ABI.
- MIPSpro N32 ABI Handbook.
- SGI assembly reference manual. Pages 2-7 describe register usage for three ABIs (-32, -n32 -64, where these latter two are running on 64bit hardware, and get to use 32 fp regs).
Mach-O ABI for PowerPC (Mac OS X)
System V ABI for SPARC
- 64 Bit Supplement
- Solaris 64-bit Developer's Guide

SIMD Vectorization references:

Etc.:

AMD64 docs.
IA-32 Intel Arch & ISA Manuals. Also includes Intel's description of EM64T instructions (oh my gosh, some of this looks almost exactly like the AMD64 docs! Whatever could be going on?).
cpuid: site with simple SSE instructions lists, as well as some arch info.
AMD block fetch whitepaper.

In addition to the above links, I had some actual paper books for learning various assemblies. They include:
