Maciej W. Rozycki 17c6c9d9f3 MIPS: Fix the encoding of immediates with microMIPS JALX
The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation
with microMIPS J/JAL/JALS instructions, however unlike the latters its
encoded immediate argument is unusually shifted left by 2 rather than 1
in calculating the value used for the operation requested.

We already handle this exception in `mips_elf_calculate_relocation' in
LD, in a scenario where JALX is produced as a result of relaxing JAL for
the purpose of making a cross-mode jump.  We also get it right in the
disassembler in `decode_micromips_operand'.

What we don't correctly do however is processing microMIPS JALX produced
by GAS from an assembly source, where a non-zero constant argument or a
symbol reference with a non-zero in-place addend has been used.  In this
case the same calculation is made as for microMIPS J/JAL/JALS, causing
the wrong encoding to be produced by GAS on making an object file, and
then again by LD in the final link.  The latter in particular causes the
calculation, where the addend fits in the relocatable field, to produce
different final addresses for the same source code depending on whether
REL or RELA relocations are used.

Correct these issues by special-casing microMIPS JALX in the places that
have been previously missed.

	bfd/
	* elfxx-mips.c (mips_elf_read_rel_addend): Adjust the addend for
	microMIPS JALX.

	gas/
	* config/tc-mips.c (append_insn): Correct the encoding of a
	constant argument for microMIPS JALX.
	(tc_gen_reloc): Correct the encoding of an in-place addend for
	microMIPS JALX.

BFD is an object file library.  It permits applications to use the
same routines to process object files regardless of their format.

BFD is used by the GNU debugger, assembler, linker, and the binary
utilities.

The documentation on using BFD is scanty and may be occasionally
incorrect.  Pointers to documentation problems, or an entirely
rewritten manual, would be appreciated.

There is some BFD internals documentation in doc/bfdint.texi which may
help programmers who want to modify BFD.

BFD is normally built as part of another package.  See the build
instructions for that package, probably in a README file in the
appropriate directory.

BFD supports the following configure options:

  --target=TARGET
	The default target for which to build the library.  TARGET is
	a configuration target triplet, such as sparc-sun-solaris.
  --enable-targets=TARGET,TARGET,TARGET...
	Additional targets the library should support.  To include
	support for all known targets, use --enable-targets=all.
  --enable-64-bit-bfd
	Include support for 64 bit targets.  This is automatically
	turned on if you explicitly request a 64 bit target, but not
	for --enable-targets=all.  This requires a compiler with a 64
	bit integer type, such as gcc.
  --enable-shared
	Build BFD as a shared library.
  --with-mmap
	Use mmap when accessing files.  This is faster on some hosts,
	but slower on others.  It may not work on all hosts.

Report bugs with BFD to bug-binutils@gnu.org.

Patches are encouraged.  When sending patches, always send the output
of diff -u or diff -c from the original file to the new file.  Do not
send default diff output.  Do not make the diff from the new file to
the original file.  Remember that any patch must not break other
systems.  Remember that BFD must support cross compilation from any
host to any target, so patches which use ``#ifdef HOST'' are not
acceptable.  Please also read the ``Reporting Bugs'' section of the
gcc manual.

Bug reports without patches will be remembered, but they may never get
fixed until somebody volunteers to fix them.
