Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted. So we end up initializing properly
at the top only to reset it at the end all the time.

Continuing my series of fixes on the SystemTap SDT support for the
ARM/AArch64 architectures, this patch now extends how ARM's SDT specific
parser handles literal numbers (immediates).
Currently, it only accepts "#" as the prefix. However, according to
"info '(as) ARM-Chars'", expressions can also have "$" and nothing as a
prefix. This patch extends the parser to accept those options.

* arm-linux-tdep.c (arm_stap_is_single_operand): Accept "$" as a
literal prefix. Also accept no prefix at all.
(arm_stap_parse_special_token): Likewise.
(arm_linux_init_abi): Likewise.
This commit implements the needed bits for SystemTap SDT probe support
on AArch64 architectures.
First, I started by looking at AArch64 assembly specification and
filling the necessary options on gdbarch's stap machinery in order to
make the generic asm parser (implemented in stap-probe.c) recognize
AArch64's asm.
After my last patch for the SystemTap SDT API, which extends it in order
to accept multiple prefixes and suffixes, this patch became simpler. I
also followed Marcus suggestion and did not shared code between 32- and
64-bit ARM.
Tom asked me in a previous message how I did my tests. I believe I
replied that, but just in case: I ran the tests on
gdb.base/stap-probe.exp by hand. I also managed to run the tests on
real hardware, and they pass without regressions.

[PATCH] Allow 64-bit enum values
http://www.sourceware.org/ml/gdb-patches/2012-03/msg00772.html
... introduced a change in the gdb.Fields API without documenting it:
| I took a separate approach from the one I took in:
|
| http://sourceware.org/ml/gdb-patches/2012-02/msg00403.html
|
| and removed the overloaded meaning of the bitpos location variable to
| fix PR symtab/7259. In the following patch, I introduce a separate
| field_location union member 'enumval' which can accept LONGEST and
| hence expand enum values to 64-bit signed values. With this change,
| bitpos now only is used for (non-negative) offsets into structures,
| since the other overload of bitpos (range bounds) were already
| separated into struct range_bound.
This patch updates the documentation to reflect that change.
gdb/doc/ChangeLog:
* gdb.texinfo (Types In Python): Fix the documentation of
attribute "bitpos" in class gdb.Field for enum types. Add
documentation for attribute "enumval" in that same class.
This is to make it easier to discover the various options displayed
by the -list-features command.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Support Commands): Change @table into
@ftable.
* gdb.texinfo (Auto-loading): Move menu up. Move discussion of
auto-loaded objfile scripts and .debug_gdb_scripts section to their
corresponding section in Extending GDB.

This patch does some basic cleanups on the SystemTap SDT probes API. It
removes spurious newlines, brackets, reindents some code, and do
explicit checks for NULL, NUL, and 0 where applicable.

* stap-probe.c (struct stap_probe) <args_parsed>: Add comment.
(stap_is_generic_prefix): Delete extra brackets. Reindent.
(stap_parse_register_operand): Remove spurious newlines. Simplify

A number of commands provide the capability to query the debugger
about support for various features, and one of them in particular
(-list-features), is expected to grow as new features get added.
-list-target-features should also grow a bit over time, but probably
slower.
These commands deserve their own section and @node.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI): Add "GDB/MI Support Commands" entry
in menu.
(GDB/MI Variable Objects): Adjust reference to "-list-features"
command, now in a new node.
(GDB/MI Support Commands): New node, with its contents being
extracted from the "GDB/MI Miscellaneous Commands" node.
A small paragraph introducing the section is also added at
the start.
(GDB/MI Miscellaneous Commands): Delete the description of the
-info-gdb-mi-command, -list-features and -list-target-features
commands, now hosted in the "GDB/MI Support Commands" node.
Don't attempt to merge CIEs with a larger number of insns than will
fit in the buffer.
* elf-eh-frame.c (cie_eq): Return false when initial_insn_length
is too large.
(cie_compute_hash): Don't exceed bounds of initial_instructions.
(_bfd_elf_parse_eh_frame): Always set initial_insn_length, and
save as much of insns to initial_instructions[] as will fit.
