One must build yasm (included in the yasm directory) before building GMP, if building on an x86_64 machine. Note: make test and make tune do not currently build.

yasm_objfmts \- Yasm Supported Object Formats
|
|
.SH "SYNOPSIS"
|
|
.HP 5
|
|
\fByasm\fR \fB\-f\ \fR\fB\fIobjfmt\fR\fR \fB\fI...\fR\fR
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
The standard Yasm distribution includes a number of modules for different object formats (Yasm's primary output).
|
|
.PP
|
|
The object format is selected on the
|
|
\fByasm\fR(1)
|
|
command line by use of the
|
|
\fB\-f \fR\fB\fIobjfmt\fR\fR
|
|
command line option.
|
|
.SH "BIN"
|
|
.PP
|
|
The
|
|
\(lqbin\(rq
|
|
object format produces a flat\-format, non\-relocatable binary file. It is appropriate for producing DOS .COM executables or things like boot blocks. It supports only 3 sections and those sections are written in a predefined order to the output file.
|
|
.SH "COFF"
|
|
.PP
|
|
The COFF object format is an older relocatable object format used on older Unix and compatible systems, and also (more recently) on the DJGPP development system for DOS.
|
|
.SH "DBG"
|
|
.PP
|
|
The
|
|
\(lqdbg\(rq
|
|
object format is not a
|
|
\(lqreal\(rq
|
|
object format; the output file it creates simply describes the sequence of calls made to it by Yasm and the final object and symbol table information in a human\-readable text format (that in a normal object format would get processed into that object format's particular binary representation). This object format is not intended for real use, but rather for debugging Yasm's internals.
|
|
.SH "ELF"
|
|
.PP
|
|
The ELF object format really comes in two flavors:
|
|
\(lqelf32\(rq
|
|
(for 32\-bit targets) and
|
|
\(lqelf64\(rq
|
|
(for 64\-bit targets). ELF is a standard object format in common use on modern Unix and compatible systems (e.g. Linux, FreeBSD). ELF has complex support for relocatable and shared objects.
|
|
.SH "MACHO"
|
|
.PP
|
|
The Mach\-O object format really comes in two flavors:
|
|
\(lqmacho32\(rq
|
|
(for 32\-bit targets) and
|
|
\(lqmacho64\(rq
|
|
(for 64\-bit targets). Mach\-O is used as the object format on MacOS X. As Yasm currently only supports x86 and AMD64 instruction sets, it can only generate Mach\-O objects for Intel\-based Macs.
|
|
.SH "RDF"
|
|
.PP
|
|
The RDOFF2 object format is a simple multi\-section format originally designed for NASM. It supports segment references but not WRT references. It was designed primarily for simplicity and has minimalistic headers for ease of loading and linking. A complete toolchain (linker, librarian, and loader) is distributed with NASM.
|
|
.SH "WIN32"
|
|
.PP
|
|
The Win32 object format produces object files compatible with Microsoft compilers (such as Visual C++) that target the 32\-bit x86 Windows platform. The object format itself is an extended version of COFF.
|
|
.SH "WIN64"
|
|
.PP
|
|
The Win64 object format produces object files compatible with Microsoft compilers that target the 64\-bit
|
|
\(lqx64\(rq
|
|
Windows platform. This format is very similar to the win32 object format, but produces 64\-bit objects.
|
|
.SH "XDF"
|
|
.PP
|
|
The XDF object format is essentially a simplified version of COFF. It's a multi\-section relocatable format that supports 64\-bit physical and virtual addresses.
