Revert "build: Include pregenerated nasm manpages"
This reverts commit 99427bdb6c.
We don't include generated files in the repository, instead we should
pregenerate them for the tarball generation, just as we do for the
Perl-generated files.

The \fBnasm\fR command assembles the file \fIfilename\fR and directs output to the file \fIoutfile\fR if specified\&. If \fIoutfile\fR is not specified, \fBnasm\fR will derive a default output file name from the name of its input file, usually by appending \(oq\&.o\(cq or \(oq\&.obj\(cq, or by removing all extensions for a raw binary file\&. Failing that, the output file name will be \(oqnasm\&.out\(cq\&.

|
|
||||||
.sp
|
|
||||||
\fIConstants\fR may be expressed numerically in most formats: a trailing H, Q or B denotes hex, octal or binary respectively, and a leading \(oq0x\(cq or \(oq$\(cq denotes hex as well\&. Leading zeros are not treated specially at all\&. Character constants may be enclosed in single or double quotes; there is no escape character\&. The ordering is little\-endian (reversed), so that the character constant \fI\*(Aqabcd\fR\*(Aq denotes 0x64636261 and not 0x61626364\&.

|
||||||
.sp
|
|

Local labels begin with a period, and their \(oqlocality\(cq is granted by the assembler prepending the name of the previous non\-local symbol\&. Thus declaring a label \(oq\&.loop\(cq after a label \(oqlabel\(cq has actually defined a symbol called \(oqlabel\&.loop\(cq\&.

||||||
.SH "DIRECTIVES"
|
|
||||||
.sp
|
|
||||||
\fISECTION\fR \fIname\fR or \fISEGMENT\fR \fIname\fR causes \fBnasm\fR to direct all following code to the named section\&. Section names vary with output file format, although most formats support the names \fI\&.text\fR, \fI\&.data\fR and \fI\&.bss\fR\&. (The exception is the \fIobj\fR format, in which all segments are user\-definable\&.)
|
|
||||||
.sp
|
|
||||||
\fIABSOLUTE\fR \fIaddress\fR causes \fBnasm\fR to position its notional assembly point at an absolute address: so no code or data may be generated, but you can use \fIRESB\fR, \fIRESW\fR and \fIRESD\fR to move the assembly point further on, and you can define labels\&. So this directive may be used to define data structures\&. When you have finished doing absolute assembly, you must issue another \fISECTION\fR directive to return to normal assembly\&.
|
|
||||||
.sp
|
|
||||||
\fIBITS\fR \fI16\fR, \fIBITS\fR \fI32\fR or \fIBITS\fR \fI64\fR switches the default processor mode for which \fBnasm\fR is generating code: it is equivalent to \fIUSE16\fR or \fIUSE32\fR in DOS assemblers\&.
|
|
||||||
.sp
|
|
||||||
\fIEXTERN\fR \fIsymbol\fR and \fIGLOBAL\fR \fIsymbol\fR import and export symbol definitions, respectively, from and to other modules\&. Note that the \fIGLOBAL\fR directive must appear before the definition of the symbol it refers to\&.
|
|
||||||
.sp
|
|
||||||
\fISTRUC\fR \fIstrucname\fR and \fIENDSTRUC\fR, when used to bracket a number of \fIRESB\fR, \fIRESW\fR or similar instructions, define a data structure\&. In addition to defining the offsets of the structure members, the construct also defines a symbol for the size of the structure, which is simply the structure name with \fIsize\fR tacked on to the end\&.
|
|
||||||
.SH "FORMAT-SPECIFIC DIRECTIVES"
|
|
||||||
.sp
|
|
||||||
\fIORG\fR \fIaddress\fR is used by the \fIbin\fR flat\-form binary output format, and specifies the address at which the output code will eventually be loaded\&.
|
|
||||||
.sp
|
|
||||||
\fIGROUP\fR \fIgrpname\fR \fIseg1\fR \fIseg2\fR\&... is used by the obj (Microsoft 16\-bit) output format, and defines segment groups\&. This format also uses \fIUPPERCASE\fR, which directs that all segment, group and symbol names output to the object file should be in uppercase\&. Note that the actual assembly is still case sensitive\&.
|
|
||||||
.sp
|
|
||||||
\fILIBRARY\fR \fIlibname\fR is used by the \fIrdf\fR output format, and causes a dependency record to be written to the output file which indicates that the program requires a certain library in order to run\&.
|
|
||||||
.SH "MACRO PREPROCESSOR"
|
|
||||||
.sp
|
|
||||||
Single\-line macros are defined using the \fI%define\fR or \fI%idefine\fR commands, in a similar fashion to the C preprocessor\&. They can be overloaded with respect to number of parameters, although defining a macro with no parameters prevents the definition of any macro with the same name taking parameters, and vice versa\&. \fI%define\fR defines macros whose names match case\-sensitively, whereas \fI%idefine\fR defines case\-insensitive macros\&.
|
|
||||||
.sp
|
|
||||||
Multi\-line macros are defined using \fI%macro\fR and \fI%imacro\fR (the distinction is the same as that between \fI%define\fR and \fI%idefine\fR), whose syntax is as follows
|
|
||||||
.sp
|
|
||||||
.if n \{\
|
|
||||||
.RS 4
|
|
||||||
.\}
|
|
||||||
.nf
|
|
||||||
%macro name minprm[\-maxprm][+][\&.nolist] [defaults]
|
|
||||||
<some lines of macro expansion text>
|
|
||||||
%endmacro
|
|
||||||
.fi
|
|
||||||
.if n \{\
|
|
||||||
.RE
|
|
||||||
.\}
|
|
||||||
.sp
|
|
||||||
Again, these macros may be overloaded\&. The trailing plus sign indicates that any parameters after the last one get subsumed, with their separating commas, into the last parameter\&. The \fIdefaults\fR part can be used to specify defaults for unspecified macro parameters after \fIminparam\fR\&. \fI%endm\fR is a valid synonym for \fI%endmacro\fR\&.
|
|
||||||
.sp
|
|
||||||
To refer to the macro parameters within a macro expansion, you use \fI%1\fR, \fI%2\fR and so on\&. You can also enforce that a macro parameter should contain a condition code by using \fI%+1\fR, and you can invert the condition code by using \fI%\-1\fR\&. You can also define a label specific to a macro invocation by prefixing it with a double \(oq%\(cq sign\&.
|
|
||||||
.sp
|
|
||||||
Files can be included using the \fI%include\fR directive, which works like C\&.
|
|
||||||
.sp
|
|
||||||
The preprocessor has a \(oqcontext stack\(cq, which may be used by one macro to store information that a later one will retrieve\&. You can push a context on the stack using \fI%push\fR, remove one using \fI%pop\fR, and change the name of the top context (without disturbing any associated definitions) using \fI%repl\fR\&. Labels and \fI%define\fR macros specific to the top context may be defined by prefixing their names with %$, and things specific to the next context down with %$$, and so on\&.
|
|
||||||
.sp
|
|
||||||
Conditional assembly is done by means of \fI%ifdef\fR, \fI%ifndef\fR, \fI%else\fR and \fI%endif\fR as in C\&. (Except that \fI%ifdef\fR can accept several putative macro names, and will evaluate TRUE if any of them is defined\&.) In addition, the directives \fI%ifctx\fR and \fI%ifnctx\fR can be used to condition on the name of the top context on the context stack\&. The obvious set of \(oqelse\-if\(cq directives, \fI%elifdef\fR, \fI%elifndef\fR, \fI%elifctx\fR and \fI%elifnctx\fR are also supported\&.
