PrefaceThis Executable and Linking Format Specification, Version 1.2, is the result of the work of theTool Interface Standards (TIS) Committee--an association of members of the microcomputerindustry formed to work toward standardization of the software interfaces visible todevelopment tools for 32-bit Intel Architecture operating environments. Such interfacesinclude object module formats, executable file formats, and debug record information andformats.The goal of the committee is to help streamline the software development process throughoutthe microcomputer industry, currently concentrating on 32-bit operating environments. To thatend, the committee has developed specifications--some for file formats that are portable acrossleading industry operating systems, and others describing formats for 32-bit Windows*operating systems. Originally distributed collectively as the TIS Portable FormatsSpecifications Version 1.1, these specifications are now separated and distributed individually.TIS Committee members include representatives from Absoft, Autodesk, Borland InternationalCorporation, IBM Corporation, Intel Corporation, Lahey, Lotus Corporation, MetaWareCorporation, Microtec Research, Microsoft Corporation, Novell Corporation, The Santa CruzOperation, and WATCOM International Corporation. PharLap Software Incorporated andSymantec Corporation also participated in the specification definition efforts.This specification like the others in the TIS collection of specifications is based on existing,proven formats in keeping with the TIS Committee's goal to adopt, and when necessary, extendexisting standards rather than invent new ones.About ELF: Executable and Linking FormatThe Executable and Linking Format was originally developed and published by UNIX SystemLaboratories (USL) as part of the Application Binary Interface (ABI). The Tool InterfaceStandards committee (TIS) has selected the evolving ELF standard as a portable object fileformat that works on 32-bit Intel Architecture environments for a variety of operating systems.The ELF standard is intended to streamline software development by providing developerswith a set of binary interface definitions that extend across multiple operating environments.This should reduce the number of different interface implementations, thereby reducing theneed for recoding and recompiling code.About This DocumentThis document is intended for developers who are creating object or executable files on various32-bit environment operating systems. In order to extend ELf into different operating systems,the current ELF version 1.2 document has been reorganized based on operating system-specificinformation. It is divided into the following three books: Book I: Executable and Linking Format, describes the object file format called ELF. This bookalso contains an appendix that describes historical references and lists processor and operatingsystem reserved names and words. Book II: Processor Specific (Intel Achitecture), conveys hardware-specific ELF information,such as Intel Architecture information. Book III: Operating System Specific, describes ELF information that is operating systemdependent, such as System V Release 4 information. This book also contains an appendix thatdescribes ELF information that is both operating system and processor dependent.iii

reduction of the generated executable size. In this paper, we aim to analyze the effects of optimizations of LLVM compiler on the reduction of executable size. Specifically, we take the size of the executable as a metric and attempt to divide the -Oz series into logical groups and study their individual effects; while also study the effect of .
