I happen to see that argument pc is not used inside disas_aarch64_insn
at all. This patch is to remove it.
OK to apply?

As reported by Ulrich here:
https://sourceware.org/ml/gdb-patches/2015-09/msg00604.html
The system compiler (gcc 4.1) in Centos 5 doesn't like that we cast to a
pointer to a type that doesn't exist. I see no real value in using this
kind iof construct over just using void *. So this patch changes the
tdep_info field to void * and removes the casts. Even in C++, we
should not need an explicit cast when assigning to a void *.
gdb/ChangeLog:
* gdbarch.sh (struct gdbarch_info): Change tdep_info's type to void *.
* gdbarch.h: Regenerate.

I noticed this while working on the test case. I believe it would make
sense to skip running the tests if the binary failed to build. Although
I would understand the opposite argument: if the binary does not build
for some reason, we probably want to know about it, and some catastrophic
failures in the tests might alarm us better than a timid "UNTESTED".
gdb/testsuite/ChangeLog:
* gdb.python/py-type.exp: Do not run tests if binaries fail to
build.
Architectures which use RETURN_VALUE_STRUCT_CONVENTION will have a
NULL return value after executing a finish command. See get_return_value()
in infcmd.c.
This patch avoids an eventual SIGSEV (caused by attempting to
derefrence a NULL pointer) by adding a suitable test to
finish_command_fsm_should_stop().
I encountered this problem while testing msp430:
(gdb) PASS: gdb.base/structs.exp: zed L<n> for finish; return 1 structs-tc
finish

The FT32 simulator was not correctly simulating the behavior of the
program memory (PM) write port. When it is locked, writes to the
data register do nothing.
We can't use the output section size to copy input section since
--interleave will shrink the output section. Instead, we change
bfd_convert_section_contents to return the updated input section
size. When we do that, we don't need to adjust the output section
size to skip gap fills.

In objcopy, copy_object calls copy_section to copy contents of input
section to output section. When --gap-fill= is used, objcopy extends
the size of output sectios to fill gaps between output sections with
gap fills. In this case, we adjust the output section size to skip
gap files to avoid reading beypond the input section buffer before
calling copy_section and restore the output section size after input
sections have been copied.
