dfb2ce8d2e Define VG_CLREQ_SZB correctly on ARM, so Cachegrind and Callgrind
don't assert in their regtests on ARM.  (Value is the same in both
ARM and Thumb mode, fortunately.)

a1ae66b03f More unwind fixes for the amd64-linux CALL_FN_*_* macros, as per
bug 243270 comments 47 and 48:
* use __builtin_dwarf_cfa(), not __builtin_frame_address(0), to get the CFA
* use correct register specifier in VALGRIND_CFI_PROLOGUE

b8cadb97c9 Only enable CFI annotations when __GCC_HAVE_DWARF2_CFI_ASM is defined. This should work for all platforms, all gcc versions and with and without -fno-dwarf2-cfi-asm / -fno-asynchronous-unwind-tables. Thanks to Jakub Jelinek for the hint.

19bc251432 arm-linux: determine whether the host supports Neon by looking at our

11f94ef626 Make error messages at start-up more consistent. Every line of such
messages now begin with "valgrind: ", and they're more often printed before
the preamble.  This required introducing a new message kind, Vg_FailMsg, and
functions VG_(fmsg) and VG_(fmsg_bad_option), and removing
VG_(err_bad_option).

Where we used to have horrible output like this:

    [ocean:~/grind/ws2] vg5 --tool=massif --threshold=101 date
    ==31877== Massif, a heap profiler
    ==31877== Copyright (C) 2003-2010, and GNU GPL'd, by Nicholas Nethercote
    ==31877== Using Valgrind-3.6.0.SVN and LibVEX; rerun with -h for copyright info
    ==31877== Command: date
    ==31877== 
    ==31877== --threshold must be between 0.0 and 100.0
    valgrind: Bad option '--threshold'; aborting.
    valgrind: Use --help for more information.

We now have nice output like this:

    [ocean:~/grind/ws2] vg2 --tool=massif --threshold=101 date
    valgrind: Bad option: --threshold=101
    valgrind: --threshold must be between 0.0 and 100.0

6fd0eb7b07 Merged the MACOSX106 branch to the trunk. Merge command:
svn merge -r11143:HEAD svn://svn.valgrind.org/valgrind/branches/MACOSX106

There were some easy-to-resolve conflicts.

Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT.  I just
overwrote the trunk versions with the branch versions.

dfdf90ef27 Make the version number available in the valgrind.h headers, so

eb5d6433bd Followup fix to r11006. Don't pass va_list by value through client
requests, since there's no guarantee it is the same size as a machine
word.

This renames the private client request VG_USERREQ__INTERNAL_PRINTF to
VG_USERREQ__INTERNAL_PRINTF_VALIST_BY_REF and changes the
argument-passing accordingly.

The public client requests VG_USERREQ__PRINTF and
VG_USERREQ__PRINTF_BACKTRACE are now deprecated, and handled only in
the case where sizeof(UWord) == sizeof(va_list).  In all other cases V
will now print a detailed error message and abort.  This breaks binary
compatibility of apps compiled using VALGRIND_PRINTF and
VALGRIND_PRINTF_BACKTRACE, but that's not easy to avoid.

VG_USERREQ__PRINTF and VG_USERREQ__PRINTF_BACKTRACE are now replaced
by VG_USERREQ__PRINTF_VALIST_BY_REF and
VG_USERREQ__PRINTF_BACKTRACE_VALIST_BY_REF.  The end-user macros
VALGRIND_PRINTF and VALGRIND_PRINTF_BACKTRACE have been adjusted to
use these new requests instead.

Overall result is that source level compatibility of code using
VALGRIND_PRINTF{,_BACKTRACE} is retained, but binary level
compatibility may be broken, necessitating a rebuild of code using
these macros.

f75c360fc1 Apparently the dynamic linker on ARM-Linux has soname "ld-linux.so.3"

pretty much usable on ARM-Linux.
