Defining linkrelax to have different values in as.c and tc-msp430.c /
tc-mn10300.c is at least rather tricky, and seems fragile, when we can just set
it in md_begin instead.
gas/ChangeLog:
2016-05-16 Trevor Saunders <tbsaunde+binutils@tbsaunde.org>
* config/tc-mn10300.c (md_begin): set linkrelax here instead of
defining it.
* config/tc-msp430.c (md_begin): Likewise.
PR gas/18581
* config/tc-mn10200.c (md_assemble <mdr>): Move restore_line_pointer
call to where input line used to be restored.
* config/tc-mn10300.c (md_assemble <usp>): Remove redundant input
line restore.
* config/tc-tilepro.c (parse_reg_expression): Add regname var.
Do not regard weak symbols as having a known location.
(md_estimate_size_before_relax): Use new function.
(md_pcrel_from): Do not compute a pcrel against a weak symbol.
* config/tc-mn10300.h (TC_FORCE_RELOCATION): Call mn10300_force_relocation.
* elf-m10300.c (mn10300_elf_final_link_relocate): Prevent the accidental termination of DWARF location list entries.
(mn10300_elf_relax_delete_bytes): Stop deletion if an align reloc is encountered that is larger than or not a mutliple of the number of bytes being deleted.
When adjusting symbols, any symbols inside the region being deleted must be moved to the end of the region.
Move align relocs forward if there is room for them after the deletion of the region.
* reloc.c (BFD_RELOC_MN10300_ALIGN): Add.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenerate.
* elf-m10300.h: Handle R_MN10300_ALIGN relocs.
* mn10300_elf_relax_delete_bytes): Honour R_MN10300_ALIGN relocs.
Re-fix off by one error in comparisons.
* config/tc-mn10300.c (tc_gen_reloc): Fix test that decides when
sym_diff relocs should be generated.
(md_apply_fix): Skip R_MN10300_ALIGN relocs.
(mn10300_fix_adjustable): Do not adjust R_MN10300_ALIGN relocs.
(mn10300_handle_align): New function. Generate R_MN10300_ALIGN
relocs to record alignment requests.
* config/tc-mn10300.h (TC_FORCE_RELOCATION_SUB_SAME): Also force
R_MN10300_ALIGN relocs.
(HANDLE_ALIGN): Define. Call mn10300_handle_align.
* gas/all/gas.exp: Do not run diff1.s test for mn10300.
* ld-mn10300/mn10300.exp: Run new tests. Skip i126256 test if
a compiler is not available.
* ld-mn10300/i112045-3.s: New test.
* ld-mn10300/i112045-3.d: Expected disassembly.
* ld-mn10300/i135409.s: Rename to i135409-1.s.
* ld-mn10300/i135409.d: Rename to i135409-1.d
* ld-mn10300/i135409-2.s: New test.
* ld-mn10300/i135409-2.d: Expected symbol table.
* ld-mn10300/i36434.d: Adjust expected disassembly.
* config/tc-avr.c (mod_index): New union to allow conversion
between pointers and integers.
(md_begin, avr_ldi_expression): Use it.
* config/tc-i370.c (md_assemble): Add cast for argument to print
statement.
* config/tc-tic54x.c (subsym_substitute): Likewise.
* config/tc-mn10200.c (md_assemble): Use a union to convert the
opindex field of fr_cgen structure into a pointer so that it can
be stored in a frag.
* config/tc-mn10300.c (md_assemble): Likewise.
* config/tc-frv.c (frv_debug_tomcat): Use %p to print pointer
types.
* config/tc-v850.c: Replace uses of (int) casts with correct
types.

- allowing true forward references (which will always assume the referenced
symbols have at the point of use) through the new .eqv pseudo-op and the
new == operator
- disallowing changing .equiv-generated equates (so that the protection this
provides is both forward and backward)
- snapshotting equates when their value gets changed so that previous uses
don't get affected by the new value.
- allowing expressions in places where absolute expressions (or register
names) are needed which were not completely resolvable at the point of
their definition but which are fully resolvable at the point of use
In addition it fixes PR/288.
They should be correct now.
* gas/mn10300/relax.s: Add further tests of the relaxing of branch instructions.
* gas/mn10300/relax.d: Add expected relocations.
