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.

.Os
.Sh NAME
.Nm dwarf_lne_end_sequence
.Nd set the end of instruction sequence
.Sh LIBRARY
.Lb libdwarf
.Sh SYNOPSIS
.In libdwarf.h
.Ft "Dwarf_Unsigned"
.Fo dwarf_lne_end_sequence
.Fa "Dwarf_P_Debug dbg"
.Fa "Dwarf_Addr addr"
.Fa "Dwarf_Error *err"
.Fc
.Sh DESCRIPTION
Function
.Fn dwarf_lne_end_sequence
sets the address that indicates the end of a sequence of target machine
instructions.
.Pp
Argument
.Ar dbg
should reference a DWARF producer instance allocated using
.Xr dwarf_producer_init 3
or
.Xr dwarf_producer_init_b 3 .
.Pp
Argument
.Ar addr
specifies an address value which is the first byte after the end of a
instruction sequence.
.Pp
If argument
.Ar err
is not NULL, it will be used to store error information in case
of an error.
.Sh RETURN VALUES
On success, function
.Fn dwarf_lne_end_sequence
returns
.Dv DW_DLV_OK .
In case of an error, function
.Fn dwarf_lne_end_sequence
returns
.Dv DW_DLV_NOCOUNT
and sets the argument
.Ar err .
.Sh ERRORS
Function
.Fn dwarf_lne_end_sequence
can fail with:
.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
.It Bq Er DW_DLE_ARGUMENT
Argument
.Ar dbg
was NULL.
.It Bq Er DW_DLE_ARGUMENT
The value in argument
.Ar addr
overlapped an existing line information entry.
.It Bq Er DW_DLE_MEMORY
An out of memory condition was encountered during the execution of the
function.
