[PATCH 0/4]: gas: cleanup for MD_PCREL_FROM_SECTION

Gunther Nikl-2
Hello,

MD_PCREL_FROM_SECTION has two versions: one with a "fixS *" parameter only and
a second one with an additional "segT" parameter. Only for the single parameter
version a prototype is provided in tc.h. This patch series provides cleanups and
adds a generic prototype for the second variant to tc.h.

Regards,
Gunther Nikl

[PATCH 2/4]: moxie: use generic pcrel support

Gunther Nikl-2
In reply to this post by Gunther Nikl-2
[resent with correct reference]

The moxie target header uses md_pcrel_from, thus the local prototype and
the macro definition for MD_PCREL_FROM_SECTION are not needed.

[PATCH 3/4]: m32c: remove duplicate define and prototype

The duplication was present since the initial commit of the port.

[PATCH 4/4]: Add generic prototype for md_pcrel_from_section

Gunther Nikl-2
In reply to this post by Gunther Nikl-2
[resent with correct reference]

This patch removes the need for target headers to provide a custom prototype
for md_pcrel_from_section.

The following ports use the same interface version but with the port name as
a function prefix:

  - ia64:   ia64_pcrel_from_section
  - nds32:  nds32_pcrel_from_section
  - tic6x:  tic6x_pcrel_from_section
  - v850:   v850_pcrel_from_section
  - visium: visium_pcrel_from_section

The ports could be switched to the generic function name if desired.
