[PATCH 0/8] [ARC] Several fixes for ARC linker

[Cupertino Miranda <Cupertino dot Miranda at synopsys dot com>]

Hi,

Please find attach a series of patches fixing several identified issues for
ARC linker.


[PATCH 1/9] [ARC] Avoid creating dynamic relocs when static linked is
[PATCH 2/9] [ARC] Disable warning on absolute relocs when symbol is
[PATCH 3/9] [ARC] Reassign the symbol got information to actual

  FAIL -> UNSUPPORTED: Run pr18718 with PIE (2)
  FAIL -> UNSUPPORTED: Run pr18718 with PIE (3)
  FAIL -> UNSUPPORTED: Run pr18718 with PIE (4)

  FAIL -> UNSUPPORTED: Run pr18718 with PIC (4)

[PATCH 4/9] [ARC] Don't convert _DYNAMIC@ to _GLOBAL_OFFSET_TABLE_
[PATCH 5/9] [ARC] ARC_PC32 dynamic reloc incorrectly generated.
[PATCH 6/9] [ARC] Add RELOC_FOR_GLOBAL_SYMBOL in ARC target code.

  PASS -> FAIL: plugin claimfile lost symbol
  PASS -> FAIL: plugin claimfile replace symbol
  PASS -> FAIL: plugin claimfile resolve symbol
  PASS -> FAIL: plugin claimfile lost symbol with source
  PASS -> FAIL: plugin claimfile replace symbol with source
  PASS -> FAIL: plugin claimfile resolve symbol with source
  PASS -> FAIL: plugin 2 with source lib
  PASS -> FAIL: load plugin 2 with source
  PASS -> FAIL: plugin 3 with source lib
  PASS -> FAIL: load plugin 3 with source

  This is the case because after adding RELOC_FOR_GLOBAL_SYMBOL, the linker
  became more meticulous identifying undefined symbols.
  After breafly checking the logs, I noticed that our target fails to pass those
  tests as it aborts with a undefined symbol message. ARM for example reports
  the same undefined symbol, however it does not abort the linker.

[PATCH 7/9] [ARC] Fixed TLS for IE model.
[PATCH 8/9] [ARC] Fixed condition to generate TEXTREL.

  FAIL -> UNSUPPORTED: Run pr19579
  FAIL -> UNSUPPORTED: Run pr19579 (-z now)

[PATCH 9/9] [ARC] Corrected conditions for dynamic sections creation.

Looking forward to your review.

Cheers,
Cupertino
