ia64 ltoffx support
- From: Richard Henderson <rth at redhat dot com>
- To: binutils at sources dot redhat dot com
- Date: Thu, 5 Dec 2002 15:21:38 -0800
- Subject: ia64 ltoffx support
Assembler support. The linker already has trivial non-relaxing
support for ltoff22x and ldxmov. Relaxing support to come next.
r~
* config/ia64.c (enum reloc_func): Add FUNC_LT_RELATIVE_X.
(ia64_gen_real_reloc_type): Handle it.
(pseudo_func): Add @ltoffx.
(md_begin): Build .<ltoffx>.
(ia64_force_relocation): True for LTOFF22X and LDXMOV.
* gas/ia64/ltoff22x-1.[ds]: New.
* gas/ia64/ia64.exp: Run it.
