gas/
* config/tc-sparc.c (tc_gen_reloc): Convert BFD_RELOC_8/16/32/64
into the corresponding BFD_RELOC_8/16/32/64_PCREL relocation
when requested.
* config/tc-sparc.h (DIFF_EXPR_OK): Define to enable PC-relative
diff relocations.
(TC_FORCE_RELOCATION_SUB_LOCAL): Define to ensure only supported
relocations are made PC-relative.
(CFI_DIFF_EXPR_OK): Define to 0 to force BFD_RELOC_32_PCREL to
be used directly, since otherwise BFD_RELOC_SPARC_UA32 will be
used for .eh_frame which cannot in general be converted to a
BFD_RELOC_32_PCREL due to alignment requirements.
Applied in master.
Thanks!
