[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...

[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 differ...
