[patch] arc-elf32
- To: binutils at sources dot redhat dot com
- Subject: [patch] arc-elf32
- From: Peter dot Target at arccores dot com
- Date: Wed, 24 Jan 2001 17:12:52 +0000
Ok to apply fixes? Plus these submitted previously:
http://sources.redhat.com/ml/binutils/2001-01/msg00222.html.
Also noticed that CVS still contains test files that can be removed ->
gas/testsuite/gas/arc/alias.*, branch.*, insn3.*, math.*, sshift.*.
Cheers,
Peter

* bfd/elf32-arc.c (arc_elf_object_p): Make E_ARC_MACH_ARC6 default
architecture.
(arc_elf_final_write_processing): Make bfd_mach_arc_6 default.
2001-01-24 Peter Targett <peter.targett@arccores.com>
* config/tc-arc.c (arc_code_symbol): Make symbol value for @h30
fixup expression equal to O_constant.
(md_assemble): Call dwarf2_emit_insn.
Add include of "dwarf2dbg2.h".
* config/tc-arc.h (DWARF2_LINE_MIN_INSN_LENGTH): Define.
2001-01-24 Peter Targett <peter.targett@arccores.com>
* gas/arc/st.s: Add test case @h30 fixup.
* gas/arc/st.d: Update to suit.
