This is LLVM SVN r102604:
Limit alignment in SmallVector 8, otherwise GCC assumes 16 byte alignment.
opetaror new, and malloc only return 8-byte aligned memory on 32-bit Linux,
which cause a crash if code is compiled with -O3 (or -ftree-vectorize) and some
SmallVector code is vectorized.
RedHat's version (3.4.6 20060404 (Red Hat 3.4.6-11) is buggy, see http://farm.0xacab.net/build/show/6292
FreeBSD's version appears to work, they can pass --enable-llvm, and if make
check passes use it.
All bytecode functions are loaded in a single module, the bounds verifier is
run, and then stack protectors are inserted.
The problem is that when the next bytecode function is loaded, all functions get
run through the verifier again (including those which got the stack protector
applied), and the bounds verifier rejects it (it doesn't know about stack
protectors).
The fix is to skip running the bounds verifier when a function already has the
stack protector applied, when run in libclamav.
This affects only loading of multiple unsigned bytecodes, or an unsigned
bytecode + bytecode.cvd.
Load of a single unsigned bytecode works, and load of multiple signed bytecodes
is not affected (since the verifier is skipped there).
Solaris has 2 greps, one archaic that doesn't know -E and -F,
and one that does. Configure finds the correct one, but
'make check' was using the wrong one.
This patch makes 'lit' substitute 'grep ' with the path to the
correct grep.
Introduce another Reset() method in BumpPtrAllocator that calls a destructor
on all objects it has allocated, if they are all of the same size and alignment.
Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).
valnos is not reliable for this purpose, as seen in r99400
(which still leaked, and sometimes caused double frees).
Port LLVM commit r98349:
Author: d0k
Date: Fri Mar 12 07:54:59 2010
New Revision: 98349
Log:
Use StringRef::substr instead of std::string::substr to avoid using a free'd
string temporary. This should fix PR6590.

If call result is in ST0 and it is not being passed to the caller's
caller, then it is not safe to optimize the call into a sibcall since
the call result has to be popped off the x87 stack.

pthread_cancel is broken on Mac OS X (it only works if the thread
you want to kill calls pthread_testcancel, which is never the situation
when you need async cancelation).
Anyway async cancelation is risky, it may leave bc_ctx in an inconsistent state.
So rather than doing using pthread_cancel (or pthread_kill+siglongjmp)
just insert the timeout checks into the JITed code directly.
These are inserted in each loop, if the loop's tripcount is unknown, or
higher than a threshold. They are also inserted after a certain amount
of APIcalls are made (even in absence of loops).
Note that 'loop' in this sense is not LLVM's notion of a natural loop,
it is simply a BB which is reachable both directly and via a backedge.
For example this doesn't contain natural loops but contains backedges (and a
potential infinite loop):
int foo(int a)
{
int x=4;
if (a == 42)
goto head2;
head:
x++;
head2:
if (a >= 2) {
x += 3;
goto head;
} else if (a >= 0) {
x += 9;
goto head;
}
return x;
}

teach tblgen to be more aggressive when factoring CheckType nodes.
Now it will factor things like this:
CheckType i32
...
CheckOpcode ISD::AND
CheckType i64
...
into:
SwitchType:
i32: ...
i64:
CheckOpcode ISD::AND
...
This shrinks hte table by a few bytes, nothing spectacular.

commit 0391c33d30582e640bbae6d394c6718b3226607d
Author: Anton Korobeynikov <asl@math.spbu.ru>

Lower dynamic stack allocation on mingw32 to separate instruction.
We cannot use a normal call here since it has extra unmodelled side
effects (it changes stack pointer). This should fix PR5292.

disable this for mingw as well, we really need a 'has no dynamic linking' predicate.
