Otherwise, GOT offset will be wrong.

97f5015122 MIPS/GAS: Don't convert RELA JALR relocations on R6
Revert an inadvertent change to make RELA JALR relocations
section-relative on MIPS R6 targets made with commit 7361da2c95 ("Add
support for MIPS R6.").  There is no need to make this a special case
and the comment introduced with the said change clearly indicates this
was not intended.

cad8e26d2a gdb: Use UNSUPPORTED not XFAIL for unsupported target features
If a target does not support making function calls from GDB then in a
number of test files, we currently report an XFAIL and skip some, or all
of the tests.  This commit changes the XFAIL to an UNSUPPORTED as this
seems more appropriate in these cases.

Some of the tests used bug ID 2416 to be reported in the XFAIL.  In the
current GDB bugzilla bug 2416 has nothing to do with calling target
functions from GDB.

3b63d2cee1 [ARC] Fixes related to reordering of .got and .got.plt
- Correctly solved relocations on the .got header.
- This bug arrised from enabling RELRO (-z combreloc).
  Because the .got and .got.plt sections were split in new linker
  scripts the header is no longer part of sgotplt contents.
  Changed the patch to sgot contents instead.
- Latest fix to .got header relocs.

PR rust/20110 concerns the type of an integer constant that is too

edef7b8cf3 Fix rust-exp handling in makefile
I noticed that the rust-exp handling in the Makefile differed from
that of other .y files.  I believe I noticed this by seeing a stray
"rm" in the build log.

This patch changes the Makefile to bring the rust-exp handling in line
with that of other .y files.

2016-06-10  Tom Tromey  <tom@tromey.com>

	* Makefile.in (COMMON_OBS): Remove rust-exp.o.
	(YYFILES): Add rust-exp.c.
	(YYOBJ): Add rust-exp.o.
	(local-maintainer-clean): Remove rust-exp.c.

b2cc3f6fc2 S/390: Dump unknown instructions according to their length.
Unknown instructions are currently just dumped as .long 1234.  On
S/390 we can do a bit better since the instruction length is encoded
in the opcode.  That way also unknown instructions can be skipped
according to their real length.  That way we can continue correctly
after that instruction.  However, there are also some drawbacks with
that behavior when dumping data.  So for now that behavior is only
enabled for text section but even there it might mess things up when
having a literal pool embedded in the code.  Therefore I've left the
feature disabled by default and have added the -Minsnlength option to
enable it explicitely.

5e13cf2543 Fortran: Testsuite, non-local references in nested functions.
Non-local references in nested functions are usually implemented
by using DWARF static link. This feature was added
with commit 63e43d3aed
(DWARF: handle non-local references in nested functions) but
a testcase was missing in Fortran.

Add negative repeat count to 'x' command
This change adds support for specifying a negative repeat count to
all the formats of the 'x' command to examine memory backward.

ffc89b17f2 i386: Test external function reference without PLT
To call an external function, the direct branch to the PLT entry can be
replaced by an indirect branch via the GOT slot, which is similar to the
first instruction in the PLT slot.  Instead using the PLT slot as function
address, the function address is retrieved from the GOT slot.  The
R_386_GOT32X relocation can be used to compute the address of the symbol’s
GOT entry without base register when PIC is disabled.  In non-PIC
executable,

call/jmp *func@GOT

should be used for indirect branch via the GOT slot and

movl func@GOT, %eax

should be used to load function address.  Unlike PIC case, no register
is needed to access GOT.  If linker determines the function is defined
locally, it converts indirect branch via the GOT slot to direct branch
with a nop prefix and converts load via the GOT slot to load immediate
or lea.

6eaa7fb59b Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:

call *___tls_get_addr@GOT(%reg)

where EBX register isn't required as GOT base, instead of direct call:

call ___tls_get_addr[@PLT]

which requires EBX register as GOT base.

Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.

For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call.  For local
dynamic model, we simply use 5-byte indirect call.

TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction.  Since linker may convert

call ___tls_get_addr[@PLT]

to

addr32 call ____tls_get_addr

when producing static executable, both patterns are recognized.
