This new script has one small snafoo, which prevented the $host_alias
and $target_alias from being expanded during the generation of the
version.c file. As a result, the version info yields:
This GDB was configured as "--host=$host_alias --target=$target_alias".
^^^^^^^^^^^ ^^^^^^^^^^^^^
This patch fixes this issue.
gdb/ChangeLog:
* common/create-version.sh: Fix expansion of $host_alias
and $target_alias in generation of HOST_NAME and TARGET_NAME
(resp.).
Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.
* common/create-version.sh: New file.
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(HFILES_NO_SRCDIR): Use common/version.h.

This patch is the result of re-running the copyright.py script
in GDB, after we modified it to stop ignoring some files in
gdb/gnulib that should have been updated earlier this year.
gdb/ChangeLog:
* gdb/gnulib/Makefile.in: Update date in copyright header.
* gdb/gnulib/configure.ac: Ditto.
* gdb/gnulib/update-gnulib.sh: Ditto.
The script was excluding all of gdb/gnulib but this is no longer
correct, ever since we moved the imported files to gdb/gnulib/import.
As a result, a number of files (Makefile, etc, including this script
itself) did not have their copyright header updated. This fixes
the problem.
gdb/ChangeLog:
* copyright.py (EXCLUDE_LIST): Replace "gdb/gnulib" by
"gdb/gnulib/import".
Most modern systems have frexpl and gnulib provides an implementation
for those that don't, so use it instead of the generic but inaccurate
ldfrexp.

* doublest.c (ldfrexp): Remove function.
(convert_doublest_to_floatformat): Call frexpl instead of
ldfrexp.
* dwarf2read.c (try_open_dwop_file): New arg search_cwd.
All callers updated.
(open_dwp_file): If we can't find the dwp file, search the basename
in debug-file-directory.
This patch adds an option --skip-unavailable to MI command
-data-list-register-values, so that unavailable registers are not
displayed (on the context of traceframes).
The old -data-list-register-values command behaves like
-data-list-register-values x 0 8
^done,register-values=[{number="0",value="<unavailable>"},{number="8",value="0x80483de"}]
With this patch, an option --skip-unavailable is added,
-data-list-register-values --skip-unavailable x 0 8
^done,register-values=[{number="8",value="0x80483de"}]

We've currently got 3 files doing open coded implementations of cpuid.
Each has its own set of workarounds and varying levels of how well
they're written and are generally hardcoded to specific cpuid functions.
If you try to build the latest gdb as a PIE on an i386 system, the build
will fail because one of them lacks PIC workarounds (wrt ebx).
Specifically, we have:
common/linux-btrace.c:
two copies of cpuid asm w/specific args, one has no workarounds
while the other implicitly does to avoid memcpy
go32-nat.c:
two copies of cpuid asm w/specific args, one has workarounds to
avoid memcpy
gdb/testsuite/gdb.arch/i386-cpuid.h:
one general cpuid asm w/many workarounds copied from older gcc
Fortunately, that last header there is pretty damn good -- it handles
lots of edge cases, the code is nice & tight (uses gcc asm operands
rather than manual movs), and is already almost a general library type
header. It's also the basis of what is now the public cpuid.h that is
shipped with gcc-4.3+.
So what I've done is pull that test header out and into gdb/common/
(not sure if there's a better place), synced to the version found in
gcc-4.8.0, put a wrapper API around it, and then cut over all the
existing call points to this new header.
Since the func already has support for "is cpuid supported on this proc",
it makes it trivial to push the i386/x86_64 ifdefs down into this wrapper
API too. Now it can be safely used for all targets and gcc will elide
the unused code for us.
I've verified the gdb.arch testsuite still passes, and this code compiles
for an armv7a host as well as x86_64. The go32-nat code has been left
ifdef-ed out until someone can test & verify the new stuff works (and if
it doesn't, figure out how to make the new code work).
