305e13e67f Fix regression introduced in "break *<EXPR>" by explicit location patches.
A relatively recent patch support for explicit locations, and part
of that patch cleaned up the way we parse breakpoint locations.
Unfortunatly, a small regression crept in for "*<EXPR>" breakpoint
locations. In particular, on PIE programs, one can see the issue by
doing the following, with any program:

    (gdb) b *main
    Breakpoint 1 at 0x51a: file hello.c, line 3.
    (gdb) run
    Starting program: /[...]/hello
    Error in re-setting breakpoint 1: Warning:
    Cannot insert breakpoint 1.
    Cannot access memory at address 0x51a

    Warning:
    Cannot insert breakpoint 1.
    Cannot access memory at address 0x51a

Just for the record, this regression was introduced by:

    commit a06efdd6ef
    Date:   Tue Aug 11 17:09:35 2015 -0700
    Subject: Explicit locations: introduce address locations

What happens is that the patch makes the implicit assumption that
the address computed the first time is static, as if it was designed
to only support litteral expressions (Eg. "*0x1234"). This allows
the shortcut of not re-computing the breakpoint location's address
when re-setting breakpoints.

However, this does not work in general, as demonstrated in the example
above.

This patch plugs that hole simply by saving the original expression
used to compute the address as part of the address location, so as
to then re-evaluate that expression during breakpoint re-set.

        * location.h (new_address_location): Add new parameters
        "addr_string" and "addr_string_len".

        "addr_string" and "addr_string_len".  If not NULL, store
        a copy of the addr_string in the new location as well.
        (get_address_string_location): New function.
        (string_to_event_location): Update call to new_address_location.
        * linespec.c (event_location_to_sals) <ADDRESS_LOCATION>:
        Save the event location in the parser's state before
        passing it to convert_address_location_to_sals.

        to new_address_location.

554717a3ed Move common aarch64 HW breakpoint/watchpoint code to nat/
When I look at test fails related to watchpoint on aarch64-linux,
I find there are some code duplicates between GDB and GDBserver.
This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}.

The only change I do is about the dr_changed_t typedef, which was
ULONGEST in GDB and 'unsigned long long' in GDBserver.  Each bit
of dr_changed_t represents a status of each HW breakpoint or
watchpoint register, and the max number of HW breakpoint or watchpoint
registers is 16, so the width of 'unsigned long long' is sufficient.

607685ecee Native debug arm program by aarch64 GDB
This patch is to let aarch64 GDB debug 32-bit arm program natively.  In
each function for fetching and storing registers, GDB will check
gdbarch_bfd_arch_info (gdbarch)->bits_per_word, if it is 32, call
the corresponding aarch32 functions in aarch32-linux-nat.c, otherwise
fall back to aarch64 code to fetch and store registers.

aarch64_linux_read_description has to return the right target description,
but we don't have gdbarch available there, so GDB fetches auxv and gets
AT_PHENT, in order to determine whether the target is 32-bit or 64-bit.
I learned this trick from solib-svr4.c.

61a12cfa7b Remove HPUX
IIUC it is a pre-requisite for IPv6 support, some UNICes do not support
getaddrinfo required for IPv6.  But coincidentally such UNICes are no longer
really supported by GDB.  Therefore it was concluded we can remove all such
UNICes and then we can implement IPv6 easily with getaddrinfo.

8cc73a3902 Move code to disable ASR to nat/
This patch moves the shared code present on
gdb/linux-nat.c:linux_nat_create_inferior and
gdb/gdbserver/linux-low.c:linux_create_inferior to
nat/linux-personality.c.  This code is responsible for disabling
address space randomization based on user setting, and using
<sys/personality.h> to do that.  I decided to put the prototype of the
maybe_disable_address_space_randomization on nat/linux-osdata.h
because it seemed the best place to put it.

I regression-tested this patch on Fedora 20 x86_64, and found no
regressions.

cdf436294f Detect 64-bit-ness in PowerPC Book III-E
This patch is to teach both GDB and GDBServer to detect 64-bit inferior
correctly.  We find a problem that GDBServer is unable to detect on a
e5500 core processor.  Current GDBServer assumes that MSR is a 64-bit
register, but MSR is a 32-bit register in Book III-E.  This patch is
to fix this problem by checking the right bit in MSR, in order to handle
both Book III-S and Book III-E.  In order to detect Book III-S and
Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by
getauxval on glibc >= 2.16.  If getauxval doesn't exist, we implement
the fallback by parsing /proc/self/auxv), because it should an invariant
on the same machine cross different processes.

In order to share code, I add nat/ppc-linux.c for both GDB and
GDBserver side.

b2859a9a54 Remove (dead-code) native core file sniffers on Linux targets
Since Andreas Arnez' recent patch series, all Linux targets install
gdbarch_iterate_over_regset_sections routines.  This means that on
Linux native targets, old-style core sniffers are never used.

Most Linux targets haven't been using such sniffers for a long time
anyway, but a couple remain: ia64 and sparc use core-regset.o, and
m68k installs its own core_fns.  All this is now dead code, which
this commit removes.

2acf986b74 Don't set CC in config/i386/go32.mh
I cross-compile gdb for msdosdjgpp (both target and host is
i586-pc-msdosdjgpp), so the CC should be i586-pc-msdosdjgpp-gcc.
However, CC is set incorrectly to gcc after config/i386/go32.mh is inlined

This patch is to remove the CC setting in config/i386/go32.mh.

32a8097ba5 Delete Tru64 support
This commit does most of the mechanical removal.  IOW, the easy part.

procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h.  Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.

Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them.  That can always be
done on a separate pass, preferably by someone who can test on alpha.

A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better.  We can revisit those when we next need to touch that
code.

I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.

Built and tested on x86_64 Fedora 20, with --enable-targets=all.

Tested that building for --target=alpha-osf3 on x86_64 Fedora 20
fails with:

 checking for default auto-load directory... $debugdir:$datadir/auto-load

3831839c08 Delete IRIX support
This does most of the mechanical removal.  IOW, the easy part.

This doesn't touch procfs.c as that'd be a harder excision,
potentially affecting Solaris.

mips-tdep.c is left alone.  E.g., I didn't delete the GDB_OSABI_IRIX
enum value, nor references to it in mips-tdep.c.  Some comments
mentioning IRIX ABIs may still be relevant and I wouldn't know what to
do with them. in That can always be done on a separate pass,
preferably by someone who can test on MIPS.

I didn't remove a reference to IRIX in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.

Built and tested on x86_64 Fedora 20, with --enable-targets=all.

Tested that building for --target=mips-sgi-irix6 on x86_64 Fedora 20
fails with:

df7e526582 Rename 32- and 64-bit Intel files from "i386" to "x86"
This commit renames nine files that contain code used by both 32- and
64-bit Intel ports such that their names are prefixed with "x86"
rather than "i386".  All types, functions and variables within these
files are likewise renamed such that their names are prefixed with
"x86" rather than "i386".  This makes GDB follow the convention used
by gdbserver such that 32-bit Intel code lives in files called
"i386-*", 64-bit Intel code lives in files called "amd64-*", and code
for both 32- and 64-bit Intel lives in files called "x86-*".

This commit only renames OS-independent files.  The Linux ports of
both GDB and gdbserver now follow the i386/amd64/x86 convention fully.
Some ports still use the old convention where "i386" in file/function/
type/variable names can mean "32-bit only" or "32- and 64-bit" but I
don't want to touch ports I can't fully test except where absolutely
necessary.

0e5fae36f1 S/390: Rename source files to *-linux-*
As suggested before, rename the S/390-related source files (tdep and nat)
such that "-linux-" occurs in the file name, like with other GNU/Linux
targets.  Since no other operating system is currently supported by GDB
on this architecture, this isn't strictly necessary.  But the old names
sometimes caused GDB contributors to miss these files when performing a
change that affects all GNU/Linux targets.  The latest such incident was
observed here:

98882a2651 Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show startup-with-shell" option.
Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start").  GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.

GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).

This patch makes that setting a run-time knob instead.  This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).

d8d2a3ee47 Normalize on PATH_MAX instead of MAXPATHLEN throughout.
With the pathmax gnulib module in place, we can use PATH_MAX
consistently throughout, instead of the current mixbag of PATH_MAX and
MAXPATHLEN uses.  It's no longer necessary to include sys/param.h
(supposedly, I can't check all ports touched here) for MAXPATHLEN.

Don't remove sys/param.h from GDB's configure.ac, as later tests in
the file use HAVE_SYS_PARAM_H checks.

Tested on x86_64 Fedora 17.

Also cross-built for --host=i686-w64-mingw32, and --host=i586-pc-msdosdjgpp.
