.SH NAME
llvm-readobj \- LLVM Object Reader
.SH SYNOPSIS
.sp
\fBllvm\-readobj\fP [\fIoptions\fP] [\fIinput...\fP]
.SH DESCRIPTION
.sp
The \fBllvm\-readobj\fP tool displays low\-level format\-specific information
about one or more object files.
.sp
If \fBinput\fP is "\fB\-\fP", \fBllvm\-readobj\fP reads from standard
input. Otherwise, it will read from the specified \fBfilenames\fP\&.
.SH DIFFERENCES TO LLVM-READELF
.sp
\fBllvm\-readelf\fP is an alias for the \fBllvm\-readobj\fP tool with a
slightly different command\-line interface and output that is GNU compatible.
Following is a list of differences between \fBllvm\-readelf\fP and
\fBllvm\-readobj\fP:
.INDENT 0.0
.IP \(bu 2
\fBllvm\-readelf\fP uses \fIGNU\fP for the \fI\%\-\-elf\-output\-style\fP option
by default. \fBllvm\-readobj\fP uses \fILLVM\fP\&.
.IP \(bu 2
\fBllvm\-readelf\fP allows single\-letter grouped flags (e.g.
\fBllvm\-readelf \-SW\fP is the same as \fBllvm\-readelf \-S \-W\fP).
\fBllvm\-readobj\fP does not allow grouping.
.IP \(bu 2
\fBllvm\-readelf\fP provides \fI\%\-s\fP as an alias for
\fI\%\-\-symbols\fP, for GNU \fBreadelf\fP compatibility, whereas it is
an alias for \fI\%\-\-section\-headers\fP in \fBllvm\-readobj\fP\&.
.IP \(bu 2
\fBllvm\-readobj\fP provides \fB\-t\fP as an alias for \fI\%\-\-symbols\fP\&.
\fBllvm\-readelf\fP does not.
.IP \(bu 2
\fBllvm\-readobj\fP provides \fB\-\-sr\fP, \fB\-\-sd\fP, \fB\-\-st\fP and \fB\-\-dt\fP as
aliases for \fI\%\-\-section\-relocations\fP, \fI\%\-\-section\-data\fP,
\fI\%\-\-section\-symbols\fP and \fI\%\-\-dyn\-symbols\fP respectively.
\fBllvm\-readelf\fP does not provide these aliases, to avoid conflicting
with grouped flags.
