[LLVMdev] How to specify displacement range of a target instruction to llc
Hi,
I'm working on a project that use llvm openrisc beckend (currently not part
of the upstream). Right now I'm looking at a bug where llc generates memory
instructions that has out-of-range displacement, for example
l.sb 37668(r1), r2 in which 37668 is a 17 bit signed integer, but the
instruction only allows 16 bit signed displacement. As a result, after
running through the assembler, 37668 is encoded wrongly into -27668 because
it's being sign extended.
Can someone point to me where...

I don't think that would be a problem, I very much doubt we declare more
than 4G worth of per-cpu variables in the kernel.

[LLVMdev] x86-64 large stack offsets
Hey guys,
I'm working on a bug for x86-64 in LLVM 2.9. Well, it's actually two issues.
The assembly generated for large stack offsets has an overflow; And, once
the overflow is fixed, the displacement is too large for GNU ld to handle
it.
void fool( int long n )
{
double w[268435600];
double z[268435600];
unsigned long i;
for ( i = 0; i < n; i++ ) {
w[i] = 1.0;
z[i] = 2.0;
}
printf(" n: %lld, W %g Z %g\n", n, w[1], z[1] );
}
Here's one of the offending...

RFC: LLD range extension thunks
After looking at this for a while, I do not think that this problem is
NP-hard. With a finite "short branch" displacement k, I was not able to
come up with a gadget that could create global constraints as would be
needed to e.g. model an instance of 3SAT or vertex cover in terms of this
problem.
The problem is hard though. I believe that it is likely to be exponential
in the "short branch" displacement...

Memory accesses and determining aliasing at the MI level
...s optimisation during post-RA
scheduling, I want to be able to determine some properties about the memory
access.
If I have two registers referring to memory, how can I determine if they are
derived from the same base-pointer? Often LLVM will optimise to use
intermediate registers holding partial displacements, for example, when a
'struct' object is on the stack, the address of the start of that object
might be computed as:
R1 := SP + initialDisplacement;
then the access to a member of that object may be accessed with a member
offset from 'R1'. This can get more complicated w...

no df to test the effect of an interaccion on a lmer mixed model
Dear useRs,
I am fitting a mixed model using the function lmer from the package lme4,
but I have some problems when I try to test the effect of my factors of
interest.
First let me explain the structure of the model:
I'm measuring animal movements. Explicitly, I am interested in displacement
(straight-line distance from an initial point). Displacements are measured
longitudinally, with one measurement every 2h (up to 20h). A series of
measurements from 2 to 20h makes a "displacement series".
We have 2 study areas, with 3 individuals per study area (individuals are

Please provide repro steps. I'm inclined to believe this is a problem in the
environment, and not a core gcc bug. But those are some trippy optimization
flags, so who knows. Be sure to specify the platform you're building for (given
the sse2 flag, x86 or x86_64... but
