.IX Header "DESCRIPTION"
The \fIcheck-abi\fR script reports any potential \s-1ABI\s0 conflicts in
the files specified.  This includes the use of the
\&\fB\-fshort\-enums\fR option, the \fB\-fstack\-protector\fR option
and the \fB\-D_FORTIFY_SOURCE\fR option.  All of these can affect
passing data between functions and hence should be used uniformly
throughout the binary.
.PP
The script accepts the following command line options:
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
.PD 0
.IP "\fB\-h\fR" 4
.IX Item "-h"
.PD
Displays the usage of the script and then exits.
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
.PD 0
.IP "\fB\-v\fR" 4
.IX Item "-v"
.PD
Displays the version of the script.
.IP "\fB\-\-verbose\fR" 4
.IX Item "--verbose"
.PD 0
.IP "\fB\-V\fR" 4
.IX Item "-V"
.PD
Enables verbose mode, causing the script to detail each action it
takes.
.IP "\fB\-\-quiet\fR" 4
.IX Item "--quiet"
.PD 0
.IP "\fB\-q\fR" 4
.IX Item "-q"
.PD
Do not include the name of script in the out generated by the script.
.IP "\fB\-\-silent\fR" 4
.IX Item "--silent"
.PD 0
.IP "\fB\-s\fR" 4
.IX Item "-s"
.PD
Produce no output.  Just return an exit status.
.IP "\fB\-\-inconsitencies\fR" 4
.IX Item "--inconsitencies"
.PD 0
.IP "\fB\-i\fR" 4
.IX Item "-i"
.PD
Only report files with potential \s-1ABI\s0 problems.
.IP "\fB\-\-ignore\-unknown\fR" 4
.IX Item "--ignore-unknown"
Do not report file types that are not supported or recognised.
.IP "\fB\-\-ignore\-\fR\fIABI|enum|FORTIFY|stack\-prot\fR" 4
.IX Item "--ignore-ABI|enum|FORTIFY|stack-prot"
Disables individual \s-1ABI\s0 checks.  Multiple occurences of this option
accumulate.  Possible option values are:
.RS 4
.IP "\fB\s-1ABI\s0\fR" 4
.IX Item "ABI"
Disable checks of the general \s-1ABI\s0 information.
.IP "\fBenum\fR" 4
.IX Item "enum"
Disable checks of the \fB\-fshort\-enum\fR option.
.IP "\fB\s-1FORTIFY\s0\fR" 4
.IX Item "FORTIFY"
Disable checks of the \fB\-D_FORTIFY_SOURCE\fR option.
.IP "\fBstack-prot\fR" 4
.IX Item "stack-prot"
Disable checks of the \fB\-fstack\-protect\fR option.

.IX Item "-r=path"
.PD
Use the specified program to read the notes from the files.
.IP "\fB\-\-\fR" 4
.IX Item "--"
Stop accumulating command line options.  This allows the script to be
run on files whose names starts with a dash.
