Fix PR ld/22263 on SPARC.
This is -fpie -pie generating dynamic relocations in the text section,
simply because no TLS transitions are applied in PIE mode. The meat
of the patch is to turn calls to bfd_link_pic (info) in TLS-related code
into !bfd_link_executable (info) and there are quite a lot of them...
bfd/
* elfxx-sparc.c (sparc_elf_tls_transition): Turn call to bfd_link_pic
into call to !bfd_link_executable and tidy up.
(_bfd_sparc_elf_check_relocs): Fix formatting and tidy up.
<R_SPARC_TLS_LE_HIX22>: Turn call to bfd_link_pic into call to
!bfd_link_executable.
<R_SPARC_TLS_IE_HI22>: Likewise.
<GOT relocations>: Remove useless code, tidy and merge blocks.
<R_SPARC_TLS_GD_CALL>: Turn call to bfd_link_pic into call to
!bfd_link_executable.
<R_SPARC_WPLT30>: Tidy up.
(_bfd_sparc_elf_gc_mark_hook): Turn call to bfd_link_pic into call
to !bfd_link_executable.
(allocate_dynrelocs): Likewise.
(_bfd_sparc_elf_relocate_section): Fix formatting and tidy up.
<R_SPARC_TLS_GD_HI22>: Merge into...
<R_SPARC_TLS_GD_LO10>: ...this. Adjust 4th argument in call to
sparc_elf_tls_transition and remove redundant code.
<R_SPARC_TLS_LDM_HI22>: Turn call to bfd_link_pic into call to
!bfd_link_executable.
<R_SPARC_TLS_LDO_HIX22>: Likewise.
<R_SPARC_TLS_LE_HIX22>: Likewise. Tidy up.
<R_SPARC_TLS_LDM_CALL>: Likewise.
<R_SPARC_TLS_GD_CALL>: Likewise. Tidy up.
<R_SPARC_TLS_GD_ADD>: Likewise.
<R_SPARC_TLS_LDM_ADD>: Likewise.
<R_SPARC_TLS_LDO_ADD>: Likewise.
<R_SPARC_TLS_IE_LD>: Likewise.
ld/
* testsuite/ld-elf/tls.exp (AFLAGS_PIC): Define on SPARC.
(pr22263-1): Pass AFLAGS_PIC to the assembler.
* testsuite/ld-sparc/tlspie32.s: Add test for other 3 transitions.
* testsuite/ld-sparc/tlspie32.dd: Adjust to above.
* testsuite/ld-sparc/tlspie64.s: Add test for other 3 transitions.
* testsuite/ld-sparc/tlspie64.dd: Adjust to above.
