.Dt FINDTEXTREL 1
.Sh NAME
.Nm findtextrel
.Nd locate text relocation entries in position independent ELF executables
.Sh SYNOPSIS
.Nm
.Op Fl V
.Op Fl H
.Op Ar
.Sh DESCRIPTION
The
.Nm
utility displays information about text relocations in ELF objects
containing position independent code.
.Pp
Text relocations are usually undesirable because they require that the
text sections of objects be modified at load time, preventing the
sharing of text sections across multiple processes using a dynamic
shared object.
.Pp
Arguments
.Ar
name ELF executables to be examined.
If no files are specified, the
.Nm
utility will examine the file
.Pa a.out
in the current directory.
.Pp
The
.Nm
utility recognizes the following options:
.Bl -tag -width indent
.It Fl H
Print a brief help message.
.It Fl V
Print a version identifier and exit.
.El
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
To list text relocations in an object, use:
.Bd -literal -offset indent
% findtextrel a.out
a.out: ELF object contains text relocation records:
a.out: off: 0x530, func: main, file: a.c, line: 5
.Ed
.Sh DIAGNOSTICS
The
.Nm
may issue the following diagnostics:
.Bl -diag
.It "ELF object is not a DSO/PIE"
The ELF executable specified by argument
.Ar object
was not a position independent executable.
.It "ELF object does not contain a text relocation"
The ELF executable specified by argument
.Ar object
contained no text relocations.
.El

utility first appeared in the
.Nm elfutils
toolset from Red Hat, Inc.

utility was created by
