Since arch_definitions.h contains full description about architectures,
arch_includes.h and arch_personalities.h can be generated.
* tools/asinfo/gen_asinfo_files.sh: New file.
* bootstrap: Add it.
* tools/asinfo/arch_includes.h: Delete it.
* tools/asinfo/arch_personalities.h: Likewise.
* tools/asinfo/Makefile.am: Include Makemodule.am.
(asinfo_SOURCES): Add $(ARCH_AUX_FILES).
* tools/asinfo/README-arch: New README explaining how to add new
architecture/ABI to asinfo tool.
* tools/asinfo/.gitignore: Add generated files.

+This file describes the storage format of arch_definitions.h

+Storage format:
+/* [ARCH_SPECIFIC_DEFINE],[ACONST1,ACONST2] */
+ARCH_DESC_DEFINE(ARCH_NAME,ARCH_ABI,PASS({COMPAT_PERS1,COMPAT_PERS2,...}),\
+PASS({ALIAS1,ALIAS2,...}))
+
+ARCH_SPECIFIC_DEFINE:
+One syscallent.h header can contain several set of system calls for each
+compatible mode. And specific set can be switched by passing particular
+definition.
+So ARCH_SPECIFIC_DEFINE allows to forward a given definition, where
+!ARCH_SPECIFIC_DEFINE forwards undefined.
+If it is not required, left empty.
+
+ACONST1,ACONST2:
+It could be used to store architecture specific constants and pass them to
code.
+If is is not required each one must be set to zero.
+
+ARCH_NAME:
+The main name of architecture will be used to generate the personality
+constants.
+The personality constant is equal to ARCH_+\$ARCH_ABI+_+\$ARCH_NAME.
+
+ARCH_ABI:
+Application binary interface for a given architecture, i.e. 32bit, 64bit, oabi,
+eabi, o32 etc.
+
+COMPAT_PERS1,COMPAT_PERS2,...:
+Compatible mode for a given architecture. It should be one of personality
+constants.
+If is is not required, left empty.
+
+ALIAS1,ALIAS2,...:
+Other name of the same architecture, like x86 and i386. At least one alias
+must to be set as it shows the name of architecture while printing.
+If current ARCH_NAME is just the compatible ABI mode, left empty.

+.SH DESCRIPTION
+.B asinfo
+is a useful tool, which aimed to provide information about system calls,
+architectures, and application binary interfaces (ABIs). In the simplest
+case it provides mapping from system call name to number and reverse.
+The main advantage of tool is it can work in single/multi arch modes with
+the opportunity to show discrepancies in system call characteristics.
+Also, the single arch mode allows program to take a guess about the
+current architecture and ABI, if they are not specified. Furthermore,
+.B asinfo
+provides convenient filtering for selecting system calls.
+
+.SH OPTIONS
+.SS "Architecture parameters"
+.TP 7
+.BI "\-\-set\-arch " arch
+Specify architecture/architectures manually. The format of the
+.I arch
+expression is:
+.RS 9
+.IP
+\fIarch1\/\fR[\fB,\fIarch2\/\fR]...
+.RE
+.IP
+.TP
+.B \-\-get\-arch
+Select achitecture based on the current machine.
+.TP
+.B \-\-list-arch
+Print out all supported architectures.
+Combined use with any ABI option is permitted.
+.SS "ABI parameters"
+.TP 7
+.BI "\-\-set\-abi " abi
+Specify ABI/ABIs manually. The format of the experession is:
+.RS 9
+.IP
+\fIabi1\/\fR[\fB,\fIabi2\/\fR]...
+.RE
+.IP
+.IP
+Note that ABI should be selected for each corresponding architecture.
+In addition, the special value
+.B all
+allows to choose all ABIs for the respective architecture.
+.TP
+.B "\-\-list\-abi "
+Select all ABIs for the chosen architecture/architectures.
+.IP
+If ABI parameters are not used and only single architecture is selected, tool
+will take a guess about ABI based on the strace package build.
+.SS "System call parameters"
+.TP 7
+.BI "\-\-get\-sname " expr
+Select system calls that satisfy a filtering expression
+.I
+expr
+and print out name of system calls and numbers for each architecture/ABI.
+.TP
+.BI "\-\-get\-snum " expr
+Select system calls that satisfy a filtering expression
+.I
+expr
+and print out number of system calls and names for each architecture/ABI.
+.TP
+.B \-\-nargs
+Switch the second output system call characteristic to number of arguments.
+.SS Output formatting
+.TP 7
+.B "\-\-raw"
+Reset alignment and remove titles, use ';' as a delimiter.
+.SS Miscellaneous
+.TP 7
+.B \-h
+Print the help summary.
+.TP
+.B \-v
+Print the version number.

+.SH "FILTERING EXPRESSION"
+A filtering expression is a pattern that describes a set of syscall names,
+syscall numbers, and syscall group. The format of the expression is:
+.RS 2
+.IP
+[\fB!\fR][\fB?\fR]\,\fIvalue1\/\fR[\fB,\fR[\fB?\fR]\,\fIvalue2\/\fR]...
+.RE
+.LP
+where
+.I value
+is a symbol or number. Using an exclamation mark negates the set of values.
+For example,
+.BR \fIvalue\fR = write
+means print strictly the write system call. By contrast,
+.BR \fIvalue\fR = !write
+means to dump every system call except write. Question mark before the
+syscall qualification allows suppression of error in case no syscalls matched
+the qualification provided, that can be particularly useful in multiarch mode,
+when system call is not presented in all selected architectures. In addition,
+the special values
+.B all
+and
+.B none
+have the obvious meanings.
+.LP
+Note that some shells use the exclamation point for history
+expansion even inside quoted arguments. If so, you must escape
+the exclamation point with a backslash.
+.SS "Strict match"
+.TP 7
+.B \fIvalue\fR=\,\fIset\fR
+Print out only the specified set of system calls. For example,
+.BR \fIvalue\fR = open,close,read,write
+means to only show those four system calls.
+.SS "Regex match"
+.TP 7
+.B \fIvalue\fR=/\,\fIregex\fR
+Show only those system calls that match the
+.IR regex .
+You can use
+.B POSIX
+Extended Regular Expression syntax (see
+.BR regex (7)).
+.SS "Class match"
+.TP 7
+.BR \fIvalue\fR = %file
+.TQ
+.BR \fIvalue\fR = file " (deprecated)"
+Show all system calls which take a file name as an argument. You
+can think of this as an abbreviation for
+.BR \fIvalue\fR = open,stat,chmod,unlink,...
+Furthermore, using the abbreviation will ensure that you don't
+accidentally forget to include a call like
+.B lstat
+in the list.
+.PP
+.BR \fIvalue\fR = %process
+.TQ
+.BR \fIvalue\fR = process " (deprecated)"
+Show all system calls which involve process management.
+.PP
+.BR \fIvalue\fR = %network
+.TQ
+.BR \fIvalue\fR = network " (deprecated)"
+Show all the network related system calls.
+.PP
+.BR \fIvalue\fR = %signal
+.TQ
+.BR \fIvalue\fR = signal " (deprecated)"
+Show all signal related system calls.
+.PP
+.BR \fIvalue\fR = %ipc
+.TQ
+.BR \fIvalue\fR = ipc " (deprecated)"
+Show all IPC related system calls.
+.PP
+.BR \fIvalue\fR = %desc
+.TQ
+.BR \fIvalue\fR = desc " (deprecated)"
+Show all file descriptor related system calls.
+.PP
+.BR \fIvalue\fR = %memory
+.TQ
+.BR \fIvalue\fR = memory " (deprecated)"
+Show all memory mapping related system calls.
+.TP
+.BR \fIvalue\fR = %stat
+Show stat syscall variants.
+.TP
+.BR \fIvalue\fR = %lstat
+Show lstat syscall variants.
+.TP
+.BR \fIvalue\fR = %fstat
+Show fstat and fstatat syscall variants.
+.TP
+.BR \fIvalue\fR = %%stat
+Show syscalls used for requesting file status (stat, lstat, fstat, fstatat,
+statx, and their variants).
+.TP
+.BR \fIvalue\fR = %statfs
+Show statfs, statfs64, statvfs, osf_statfs, and osf_statfs64 system calls.
+The same effect can be achieved with
+.BR \fIvalue\fR = /^(.*_)?statv?fs
+regular expression.
+.TP
+.BR \fIvalue\fR = %fstatfs
+Show fstatfs, fstatfs64, fstatvfs, osf_fstatfs, and osf_fstatfs64 system calls.
+The same effect can be achieved with
+.BR \fIvalue\fR = /fstatv?fs
+regular expression.
+.TP
+.BR \fIvalue\fR = %%statfs
+Show syscalls related to file system statistics (statfs-like, fstatfs-like,
+and ustat). The same effect can be achieved with
+.BR \fIvalue\fR = /statv?fs|fsstat|ustat
+regular expression.
+
+.SH "EXIT STATUS"
+On success,
+.B asinfo
+returns 0. Otherwise, in case of wrong input or no matches found, 1.
+
+.SH "REPORTING BUGS"
+Problems with
+.B asinfo
+should be reported to the
+.B strace
+mailing list at <strace-devel@lists.sourceforge.net>.
