I'm working on an out-of-tree target and am having some problems with rematerialization and spilling. The target's load and store instructions affect the condition code register (CCR). Describing this in the InstrInfo.td file using Defs = [CCR] certainly prevents spills and fills from being inserted where they might clobber CCR but it also prevents the load instruction from being rematerialized because it defines a physical register (TargetInstrInfo::isReallyTriviallyReMaterial...

Hi Jakob, thanks for the advice. I'll do as you suggest and make sure that CCR is never live. I can use pseudo-instructions to bundle cmp+jump but it's not ideal because I might also have to bundle cmp+jump+jump+... into a pseudo. Also, there are several flavours of cmp instruction so I might need a lot of pseudos. That's what led me to wonder whether MachineInstrBu...

Ok, Scratching the surface this morning on Bug 1388. Happy to find that CCR has already been defined in ARMRegisterInfo.td However all uses in the instruction info tablegen files indicate that a two-value operand can't be used where a dag node expects two operands. // FIXME: should be able to write a pattern for ARMBrcond, but can't use // a two-value operand...

Hello, Good time, I want to write a source code with the model DEA CCR stochastice in R software. But I could not find any example that guides me. I need this model for my article. Where can I find the source code for this model? Is it possible to send me an example of this source code? Help me please. Thanks [[alternative HTML version deleted]]

Hey guys, i want to calculate the continuasly compounded returns for stock prices. Formula for CCR: R_t = ln(P_t/P_{t-1})*100 With R: First i have to modify the vectors, so that they have the same length and we start at the second observation. log(GOOG1[-1]/GOOG1[1:length(GOOG1)-1])*100 That does work with normal vectors. My Questions: 1) I want to use this for stock prices. so i use:...

caching_thread()s do all their work under read access to extent_commit_sem. They give up on this read access only when need_resched() tells them, or when they exit. As a result, somebody that wants a WRITE access to this sem, might wait for a long time. Especially this is problematic in cache_block_group(), which can be called on critical paths like find_free_extent() and in commit path via

Dear all, Happy New year! I have used the 'crr' function to fit the 'proportional subdistribution hazards' regression model described in Fine and Gray (1999). dat1 is a three column dataset where: - ccr is the time to event variable - Crcens is an indicator variable equal to 0 if the event was achieved, 1 if the event wasn't acheived due to death or 2 if the event wasn't achieved due to disease progression - pre is an indicator variable (and the covariate of interest) I want to investigat...

Hello, why LLVM does not define physical register limits for MIPS by overriding the TargetRegisterInfo::getRegPressureLimit function the way it’s done for X86 in x86RegisterInfo.cpp and ARM.

...ctions v7m supports, I think the main other difference that's very relevant for a code generator is that v6m always generates a fault when an unaligned access occurs, whereas v7m can support unaligned accesses for many of the load and store instructions. I think it'd be important to set the CCR register on the v7m simulation so that it always generates an alignment fault in case there's an unaligned access, i.e. setting CCR.UNALIGN_TRP to 1. To check that clang indeed only produces v6m instructions when telling it to target Cortex-m0, I think we could rely on LLVM's MC layer corr...

...and there is really no other way to do this with arbitrary instructions. If you have a compare instruction that generates a flag and a branch instruction that uses it, you want to model this dependency with an unallocatable physical register, e.g. the CPSR on ARM: // Condition code registers. def CCR : RegisterClass<"ARM", [i32], 32, (add CPSR)> { let CopyCost = -1; // Don't allow copying of status registers. let isAllocatable = 0; } This will require you to mark defs and uses (and kills), but if you're using it purely inside of a single basic block you won't h...
