Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

bfd_link_relocatable, bfd_link_pic and bfd_link_pie.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/
* bfd/aoutx.h: Replace shared, executable, relocatable and pie
fields with bfd_link_executable, bfd_link_dll,
bfd_link_relocatable, bfd_link_pic and bfd_link_pie.
* bfd/bout.c: Likewise.
* bfd/coff-alpha.c: Likewise.
