Hi Philip, Thanks for the positive response from all of you! > One question: How are you handling EOM? Error return? Custom region allocator? When running into an Out-of-memory situation we're currently only doing an error return, i.e. the compilation fails, but does so without crashing the process in which the compilation/jitting occurs. It is ok for us if llvm returns with a catchable exception and unwinds all allocated memory correctly. To increase stability for us we ha...

Hi all, I've recently been writing functions which may deal with very large arrays. And I hope to use *apply functions in the program so that the code may look nicer and the performance may be better in the following two situations. The first situation is: I'm having an array A with dim(A)==c(m,n,p). And I want to apply a function F to a group of elements in A like: 1) F is applied to every group of elements like A[i,j,] for all i and j. or 2) F is applied to every group of elements like A[i,,] for all i, or A[,j,]...

This explains why the destructors in LLVM are not always prepared to be executed in exception situations. Yes, we build LLVM with exception support. In principle, we build it with the same options like the rest of our project. Actually, I could hardly imagine that we could handle OOM situations without error handling. > For the particular cases you mentioned with auto pointers and allocati...

...ave developed a set of patches improving performance and malfunction safety of certain compiler passes and would be interested in contributing them at some point. Before proposing concrete changes, we would like to know what the general interest is with respect to making LLVM safer in out-of-memory situations. I'm in favor! I can't imagine we shouldn't be able to craft fixes that don't otherwise adversely affect LLVM. -- Rick -------------- next part -------------- A non-text attachment was scrubbed...

...a catchment's outlet. Some guys have shown that if there is a significant fit to a linear model, one can deduce the dynamic state of the basin, that is, whether erosion is as strong as rock uplift, erosion is smaller than rock uplift, or erosion is greater than rock uplift. I am thus to test 4 situations: Situation 1: a linear model is inappropriate for describing the data, the scatter is too large, and thus a linear model is unfit to explain the data. Situation 2: the linear model of the kind "y = b0 + b1 * x" is fit to describe the data, ie data points lie close to a straight line...

...About players, I can't control what the "radio index" sites are doing with my icecast streaming address, But as far as I know from my experience, the players when they getting "crazy" causing between 3-5 multiple connections for less than a 2 minutes. Not a big issue. The situation that I'm describing is very different, 20-30 (and once even almost 40) "listeners" from the same IP, for a long time. Each "listener" using true bandwidth. The IP source is from Vietnam, Korea...i really think that abusing its what I'm talking about. ( What a mobile...

I can make perfect conversation with my friend with the only exception of both parties being on private ip address. There can be four situations when a call is established. 1. A and B are not behind NATs 2. A is behind a NAT, but B is not. 3. A is not behind a NAT, but B is. 4. A and B are both behind NATs (different NAT of course). Among the four situations, 1, 2 and 3 works fine. (I guess externhost and localnet did the trick) But si...

Hi everyone, The MachineLICM pass has a heuristic such that, even in low-register-pressure situations, it will refuse to hoist "cheap" instructions out of loops. By default, when an itinerary is available, this means that all of the defined operands are available in at most 1 cycle. ARM overrides this, and provides this more-customized definition: bool ARMBaseInstrInfo:: hasLowDefLat...

Hi everybody. I'm in a discussion and someone ask me in which situation we should use the zapata.conf usecallerid set to no. I didn't have the answer. I understand what the usecallerid keyword does but I'm talking about a actual situation that is interesting to to avoid receiving the caller id. Thanks in advance! -- --------------------------------------...

I have some specs that involve the use of eval and class definitions to test code generation. I want to always start with a clean slate so none of my tests fail or succeed incorrectly due to artifacts left over from previous specs. Example of my situation Spec 1 defines class Fish class Cod < Fish Spec 2 defines class Animal class Cod < Animal In this situation the second spec will fail since Cod was previously defined to be a subclass of Fish and you can not change the superclass of a subclass in ruby without causing...

From the place where we're calling into llvm we are catching all exceptions that may occur during compilation, but normally we do not add any additional catch clauses into the llvm source itself.
