Optimization manuals

This series of five manuals describes everything you need to know about optimizing code for x86 and x86-64 family microprocessors, including optimization advices for C++ and assembly language, details about the microarchitecture and instruction timings of most Intel, AMD and VIA processors, and details about different compilers and calling conventions.

Operating systems covered: DOS, Windows, Linux, BSD, Mac OS X Intel based, 32 and 64 bits.

Note that these manuals are not for beginners.

3. The microarchitecture of Intel, AMD and VIA CPUs: An optimization guide for assembly programmers and compiler makers

This manual contains details about the internal working of various microprocessors from Intel, AMD and VIA. Topics include: Out-of-order execution, register renaming, pipeline structure, execution unit organization and branch prediction algorithms for each type of microprocessor. Describes many details that cannot be found in manuals from microprocessor vendors or anywhere else. The information is based on my own research and measurements rather than on official sources. This information will be useful to programmers who want to make CPU-specific optimizations as well as to compiler makers and students of microarchitecture.

5. Calling conventions for different C++ compilers and operating systems

This document contains details about data representation, function calling conventions, register usage conventions, name mangling schemes, etc. for many different C++ compilers and operating systems. Discusses compatibilities and incompatibilities between different C++ compilers. Includes information that is not covered by the official Application Binary Interface standards (ABI's). The information provided here is based on my own research and therefore descriptive rather than normative. Intended as a source of reference for programmers who want to make function libraries compatible with multiple compilers or operating systems and for makers of compilers and other development tools who want their tools to be compatible with existing tools.

C++ vector class library

This is a collection of C++ classes, functions and operators that makes it easier to use the the vector instructions (Single Instruction Multiple Data instructions) of modern CPUs without using assembly language. Supports the SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA, XOP, and AVX512F/BW/DQ/VL instruction sets. Includes standard mathematical functions. Can compile for different instruction sets from the same source code.

Object file converter

This utility can be used for converting object files between COFF/PE, OMF, ELF and Mach-O formats for all 32-bit and 64-bit x86 platforms. Can modify symbol names in object files. Can build, modify and convert function libraries across platforms. Can dump object files and executable files. Also includes a very good disassembler supporting the SSE4, AVX, AVX2, AVX512, FMA3, FMA4, XOP and Knights Corner instruction sets. Source code included (GPL). Manual.

Subroutine library

This is a library of optimized subroutines coded in assembly language. The functions in this library can be called from C, C++ and other compiled high-level languages. Supports many different compilers under Windows, Linux, BSD and Mac OS X operating systems, 32 and 64 bits. This library contains faster versions of common C/C++ memory and string functions, fast functions for string search and string parsing, fast integer division and integer vector division, as well as several useful functions not found elsewhere.

The package contains library files in many different file formats, C++ header file and assembly language source code. Gnu general public license applies. Manual.

ForwardCom: An open standard instruction set for high performance microprocessors

This is a proposal and discussion of how an ideal instruction set architecture can be constructed. The proposed instruction set combines the best from the RISC and CISC principles to produce a flexible, consistent, modular, orthogonal, scalable and expansible instruction set for high performance microprocessors and large vector processors.

The ForwardCom instruction set has variable-length vector registers and a special addressing mode that allows the software to automatically adapt to different microprocessors with different maximum vector lengths and make efficient loops through arrays regardless of whether the array size is divisible by the vector length. Standardization of the corresponding ecosystem of ABI standards, function libraries, compilers, etc. makes it possible to combine different programming languages in the same program.

Test programs for measuring clock cycles and performance monitoring

Test programs that I have used for my research. Can measure clock cycles and performance monitor counters such as cache misses, branch mispredictions, resource stalls etc. in a small piece of code in C, C++ or assembly. Can also set up performance monitor counters for reading inside another program. Supports Windows and Linux, 32 and 64 bit mode, multiple threads.

For experts only. Useful for analyzing small pieces of code but not for profiling a whole program.

Reference manuals and other documents can be found at Intel's web site. Intel's web site is refurnished so often that any link I could provide here to specific documents would be broken after a few months. I will therefore recommend that you use the search facilities at www.intel.com and search for 'Software Developer's Manual' and 'Optimization Reference Manual'.

Windows Installer can install, remove, and update Win32 assemblies and assemblies used by the common language runtime of the Microsoft .NET Framework. An assembly is handled by the Windows Installer as a single installer component. All of the files that constitute an assembly must be contained by a single installer component that is listed in the Component table.

Windows Installer running on Windows Vista and Windows XP can install side-by-side assemblies. Side-by-side assemblies can safely share assemblies among multiple applications and can offset the negative effects of assembly sharing, such as DLL conflicts. Instead of a single version of an assembly that assumes backward compatibility with all applications, side-by-side assembly sharing enables multiple versions of a COM or Win32 assembly to run simultaneously on the system. This improved capability to isolate applications is an important part of the Microsoft .NET Framework. For more information, see Isolated Applications and Side-by-side Assemblies.
