GCC allows incomplete enums as GNU extension.
http://gcc.gnu.org/onlinedocs/gcc/Incomplete-Enums.html
These are marked as DW_AT_declaration and won't have a size.
They can only be used in declaration or as pointer types.
You can't allocate variables or storage using such an enum type.
So don't require a size for such enum types.

decimal floating point).

If the command line option --main-stacksize is not used,
the current ulimit value is used, with a min of 1MB
and a max of 16MB. Document this min/max default formula
in the --help.
Also indicate that Valgrind supports ARMv7

Add cases for PTRACE_GETREGSET in PRE(sys_ptrace) and POST(sys_ptrace).
This fixes memcheck/tests/linux/getregset on MIPS64 platforms with kernel
that supports ptrace call with PTRACE_GETREGSET.

This change disables intercepting pthread_spin_lock() for MIPS64, similar to
r13190 for MIPS32. Used in DRD and Helgrind as a workaround for the issue
#311690.

Line numbers are off by one in some outputs since it differs on GCC version
how it will map source code to line number for the ternary operator written
in multiple lines.
This is small fix that replaces one occurrence of ternary operator with
if-then-else. The excepted outputs have been changed accordingly.
This fixes the test memcheck/tests/cond_ld_st for different platforms with
different GCC versions.
Tested on x86, i386, ARM, MIPS32, and MIPS64.

exp-32bit files needed minor update for the last store, and some mips32
platforms also need additional exp-mips32 due to different way of loading
and storing double values.
This fixes drd/tests/annotate_trace_memory on different 32-bit platforms.

Follow up to the previous change in which mips64 specific tests were added.
It covers both MIPS64-LE and MIPS64-BE.

* Addition of a function to compute size of buffer needed for VG_(mkstemp)
* Use it to dimension buffers for all VG_(mkstemp) calls.

Bug #320116. sockaddr_rc might contain some padding which might not be
initialized. Explicitly check the sockaddr_rc fields are set. That also
produces better diagnostics about which field is unitialized.

Workaround for bug #318643. Disable the tests for now so they don't
go into an infinite loop and fill up the disks on arm, ppc32 or ppc64.

This fixes:
- memcheck/tests/cond_ld and
- memcheck/tests/cond_st
for 32-bit non-ARM architectures. Tested on IA32 and MIPS32.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13401
Enable wrappers for syscalls prlimit64, process_vm_readv, process_vm_writev,
needed by the following tests:
- none/tests/rlimit64_nofile and
- none/tests/process_vm_readv_writev.
The change also adds definitions for several system calls for MIPS64.

This change removes option to define shared-memory-alignment for MIPS,
instead default value (0x40000) from MIPS Linux kernel will be used.

This change is a follow up to r13385. It removes physical copies of the
allexec c-files in none/tests/mips32/ and none/tests/mips64/ and defines
them as soft-links to a common file like other arches do.
Credits to Philippe for noticing it.

the definedness check and possible shadow temp set-to-defined be
optional. Use this to properly instrument IRLoadG and IRStoreG, so
that if the load/store does not happen, not only is the validity of
the address not checked, neither is the definedness.
This fixes a regression introduced by the COMEM branch on ARM, in
which conditional loads/stores with addresses which are undefined at
runtime and with guards which are false, would generate false errors.
Also extensively re-checked the check-generation machinery and updated
a bunch of comments.

On Ubuntu systems, ptrace_scoping could forbid a process to ptrace another.
This ptrace scoping was already handled for vgdb by using SET_PTRACER
(the valgrind process must be ptraced by vgdb when it is blocked
in a syscall).
set_ptracer is however also needed when the old mechanism --db-attach=yes
is used.
The following changes are done:
* make the set_ptracer logic callable outside gdbserver
* make set_ptracer less restrictive (i.e. allow all
processes of the user to ptrace). This removes a limitation for vgdb.
* call the set_ptracer in the child launched for --db-attach=yes
* cleaned up the ptrace scope restriction message and doc as vgdb
is now working properly by default, even with ptrace_scope enabled.

sys_get_mempolicy.
This patch add support for the PPC64 sytem calls:
259 - sys_mbind
260 - sys_get_mempolicy
261 - sys_set_mempolicy
This patch also adds the Add syscall 259, sys_mbind, support for the PPC32
platform.
The patch fixes bugzilla 318932.

With rev 13368, Valgrind obeys PT_GNU_STACK making the stack not
executable. This makes inferior function call with GDB >= 7.5 failing,
as GDB places a breakpoint on the stack, which must be decoded
and translated by Valgrind to have the inferior function call properly done.
=> introduce a special case in the conditions to allow translation
when a segment is not executable but is readable and there is a
breakpoint at the address.

Restart logic has changed in kernel, this is counterpart in Valgrind.
