Physical or Statistical Explanation for the "Funnel" Plot?
...reased. There appears to be a quick convergence and then a pretty steady variance out to a set size of 10,0000.
I'm just wondering if there is a statistical explanation out there for this convergence and it has been explored further. Thanks again.

N<-100000
X<-rnorm(N)

Hi Hal,
MachineLICM is not able to hoist anything because the address mode is not
loop invariant.
Here is a reduction of the code I am talking about.
extern const unsigned phasor[4096];
void test(unsigned* out , unsigned step_size)
{
unsigned big_step_size = step_size<<2;
int *phasor_ptr_temp_1 = &phasor[big_step_size];
for (int i = 0 ; i < 1020 ; i+=4)
out[i] = phasor_ptr_temp_1[i<<step_size];
}
I am getting slightly better code on my target (Octasic's Opus) if I return
false for shouldMerge...

[LLVMdev] Question about shouldMergeGEPs in InstructionCombining
Hello
I am not sure I understand the logic for merging GEPs in
InstructionCombining.cpp:
static bool shouldMergeGEPs(GEPOperator &GEP, GEPOperator &Src) {
// If this GEP has only 0 indices, it is the same pointer as
// Src. If Src is not a trivial GEP too, don't combine
// the indices.
if (GEP.hasAllZeroIndices() && !Src.hasAllZeroIndices() &&

Jitter Buffer issues
...DP
I use TCP for the first two to insure all voice packets are delivered to
the user. I must use UDP for the Full Duplex link to minimize latency.
When I use UDP I also use the Speex Jitter Buffer. I have run into some
issues when using it.
My first problem is minor with jitter_buffer_init(int step_size). The
initialization of buffer_margin I think this should be 1 not 0.
/*FIXME: Should this be 0 or 1?*/
jitter->buffer_margin = 0;
With it set to 0 there is a problem if jitter_buffer_get() is called
before jitter_buffer_put(). This cause all packets to be discarded due
to every...
