sim: microblaze: switch to common memory functions

Re-use the existing memory core that handles reads/writes.

This drops support for the dumpmem command, but gdb itself has
support for dumping memory regions.

The verbose command is converted to the common --verbose flag

Support for the clearstats command is dropped entirely, but no
other sim really does this, and the same thing can be done by
reloading.  If it's important (clearing cycle stats) to someone,
we can add a common function for it.

Fix fails in gdb.dwarf2/dynarr-ptr.exp

I see many fails in gdb.dwarf2/dynarr-ptr.exp on arm-linux target,
started from this

print foo.three_ptr.all^M
Cannot access memory at address 0x107c8^M
(gdb) FAIL: gdb.dwarf2/dynarr-ptr.exp: print foo.three_ptr.all
print foo.three_ptr.all(1)^M
Cannot access memory at address 0x107c8

It turns out that ":$ptr_size" is used incorrectly.

             array_ptr_label: DW_TAG_pointer_type {
                 {DW_AT_byte_size :$ptr_size }
                                  ^^^^^^^^^^
                 {DW_AT_type :$array_label}
             }

Since the FORM isn't given, and it starts with the ":", it is regarded
as a label reference by dwarf assembler.  The generated asm file on
x86_64 is

        .uleb128        6               /* Abbrev (DW_TAG_pointer_type) */
        .4byte        8 - .Lcu1_begin   <----- WRONG
        .4byte        .Llabel2 - .Lcu1_begin

Looks .Lcu1_begin is 0 on x86_64 and that is why this test passes on
x86_64.  On arm, .Lcu1_begin is an address somewhere, and the value
of DW_AT_byte_size is a very large number, so memory read request
of such large length failed.

This patch is to remove ":" and set the form explicitly.  The generated
asm file on x86_64 becomes

        .uleb128        6               /* Abbrev (DW_TAG_pointer_type) */

9 years agoAdd support for the x86 XSAVE extended state on FreeBSD/x86.
John Baldwin [Sat, 21 Feb 2015 21:43:30 +0000 (16:43 -0500)]
Add support for the x86 XSAVE extended state on FreeBSD/x86.

Recognize NT_X86_XSTATE notes in FreeBSD process cores.  Recent
FreeBSD versions include a note containing the XSAVE state for each
thread in the process when XSAVE is in use.  The note stores a copy of
the current XSAVE mask in a reserved section of the machine-defined
XSAVE state at the same offset as Linux's NT_X86_XSTATE note.

For native processes, use the PT_GETXSTATE_INFO ptrace request to
determine if XSAVE is enabled, and if so the active XSAVE state mask
(that is, the value of %xcr0 for the target process) as well as the
size of XSAVE state area.  Use the PT_GETXSTATE and PT_SETXSTATE requests
to fetch and store the XSAVE state, respectively, in the BSD x86
native targets.

In addition, the FreeBSD amd64 and i386 native targets now include
"read_description" target methods to determine the correct x86 target
description for the current XSAVE mask.  On FreeBSD amd64 this also
properly returns an i386 target description for 32-bit binaries which
allows the 64-bit GDB to run 32-bit binaries.

Note that the ptrace changes are in the BSD native targets, not the
FreeBSD-specific native targets since that is where the other ptrace
register accesses occur.  Of the other BSDs, NetBSD and DragonFly use
XSAVE in the kernel but do not currently export the extended state via
ptrace(2).  OpenBSD does not currently support XSAVE.

hard time executing some of the commands the testcase issues.

there are still problems with, say, QEMU not providing PID information when
"info inferior" is issued. As a consequence, the subsequent tests will either
fail or will not make much sense.
