Ed Maste ae500c1ff8 Update to ELF Tool Chain r3668
Highlights:
- Make sure that only TLS sections are sorted into TLS segment.
- Fixed multiple errors in "Section to Segment mapping".
- Man page updates
- ar improvements
- elfcopy: avoid filter_reloc uninitialized variable for rela
- elfcopy: avoid stripping relocations from static binaries
- readelf: avoid printing directory in front of absolute path
- readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type
- test improvements

NOTES:

Some of these changes originated in FreeBSD and simply reduce diffs
between contrib and vendor.

ELF Tool Chain ar is not (currently) used in FreeBSD, and there are
improvements in both FreeBSD and ELF Tool Chain ar that are not in
the other.

.Dt DWARF_SET_RELOC_APPLICATION 3
.Os
.Sh NAME
.Nm dwarf_set_reloc_application
.Nd set a library-wide relocation flag
.Sh LIBRARY
.Lb libdwarf
.Sh SYNOPSIS
.In libdwarf.h
.Ft int
.Fo dwarf_set_reloc_application
.Fa "int apply"
.Fc
.Sh DESCRIPTION
Function
.Fn dwarf_set_reloc_application
allows applications to specify how relocation information is to be
handled by the DWARF(3) library.
.Pp
If the argument
.Ar apply
holds a non-zero value, the library will process all the relevant
.Dq ".rel"
and
.Dq ".rela"
relocation sections and will apply the relocation records found to
their corresponding DWARF sections.
.Pp
If the argument
.Ar apply
is zero, the library will not attempt to apply any relocations.
.Pp
The default behaviour of the library is to process relocation records.
.Sh NOTES
Function
.Fn dwarf_set_reloc_application
should be called before initialising a dwarf debugging context, i.e,
it should be called by the application before calling either of the
functions
.Xr dwarf_init 3
or
.Xr dwarf_elf_init 3 .
.Sh RETURN VALUES
Function
.Fn dwarf_set_reloc_application
returns the previous value of the library-wide relocation application
flag.
.Sh ERRORS
Function
.Fn dwarf_set_reloc_application
does not return an error.
