[LLVMdev] jit X86 target compilation callback bug
...rent code sets stack pointer to invalid value in > instruction "and   esp,  16". Depending on current stack pointer value > it sometimes overwrites ecx and edx registers with next three lines. How so? The stack grows downwards, thus this realignment just equivalent to "sub esp, some_value" with some_value being less than 16. We don't use register save area inside the compilation callback, however, since we're generating stubs "by hands". > We have fixed this problem by changing this instruction to "sub  esp, > 8" (8 because this function need...

difficulty with R expressions in text/legend
...x and y objects, then displays them in the plot legend with colored boxes adjacent to them. now the hard part (for me, at least :-/), i'd like to add some text (e.g. "data set 1" and "data set 2") to each line of the legend, right before the typographically-displayed R^2 == some_value text. basically, a legend that looks like so (with the expression part evaluated and typed out correctly): data set 1 R^2 == some_value data set 2 R^2 == some_other_value i've tried a seemingly countless number of paste/substitute/expression combinations, but cannot seem to get what i'd...

[LLVMdev] jit X86 target compilation callback bug
Hi! We are running llvm jit x86 on MS Visual Studio 2005. It seems there is a bug in asm code in function X86CompilationCallback in file X86JITInfo.cpp. Current code sets stack pointer to invalid value in instruction "and esp, 16". Depending on current stack pointer value it sometimes overwrites ecx and edx registers with next three lines. We have fixed this problem by changing this

scoping goes wrong when some functions are used within others.
...on stackoverflow.com, and couldn't but notice there are quite some questions popping up that deal with scoping in relation to custom functions. I grinded my teeth on it already, and I have absolutely no clue what goes wrong. The general pattern is as follows : ff <- function(x){ y <- some_value some_function(y) } > ff(x) Error in eval(expr, envir, enclos) : object 'y' not found I tried to report this as a bug earlier, but got the message I used the wrong channel. I also don't know how to formalize it into a bug report on the report site. That's why I bring it to...

[LLVMdev] Confuse on getSCEVAtScope
...nd Loop1 are brothers (loops at the same level of the loopnest), and Loop0 have a computable backedge taken count. when i call getSCEVAtScope({{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1> , Loop1), it just give me a {{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1>, instead of {some_value, + ,4}<loop0>, where some_value is getSCEVAtScope({(32 + @edge.8265),+,32}<Loop0>, Loop1). because Loop0 have a computable backedge taken count, some_value should not be a SCEVAddRec. and later i have a look computeSCEVAtScope, and see the function do not do any thing when AddRec->...

string conversion?
...nverting the "/" to "_" for that filename. I don´t really see a way to manage this file dynamically, when I want to talk to puppet about that file: file {"$variable": whatever => "$stuff"} puppet talks about the file "some/value" and not "some_value" as the script generated - so I need something string conversion like to tell puppet to replace the chars like the script does. Is there any way to do this? Thanks a lot for your help! _______________________________________________ Puppet-users mailing list Puppet-users@madstop.com https...

Data Frame Search Slow
...e on the internet once I get to the bottom of this. Basically, the set-up to the problem is like this: 1. I have a data frame with dim (2547290, 4) 2. I need to make SQL like lookups on the dataframe. I have been using the following sort of syntax: a.dataframe[a.dataframe[[column_index]] %in% some_value, ] 3. This process takes quite a lot of time (~2 seconds) on m1.small instances AMIs (AWS) So, I hope I can get that look-up/search logic quite a lot faster. I have heard that using matrices is the way to do it but I haven't found any resources on performing that sort of operation specific...

latest cvs head makes api more strongly typed
In previous versions the following would work as you expect with a dynamic language like Ruby. Method signature of wxGrid::SetRowLabelSize void SetRowLabelSize(int width) ex. gird = Wx::Grid.new(....) grid.set_row_label_size(some_value*0.5) which Ruby translates to gird = Wx::Grid.new(....) grid.set_row_label_size((some_value*0.5).to_i) In the latest cvs head you get this error: `set_row_label_size'': in method ''SetRowLabelSize'', argument 2 of type ''int'' (TypeError) Basically the i...

Background thread - entension code - switch contexts
Hi, I am using wxRuby 1.9.7 and Ruby 1.8.6. I have built an extension in C++ and used swig to load it into Ruby interpreter, which works great. The extension is an often long executing algorithm, and I''ve noticed that if I fork a new Ruby thread in button clicked event, and in this thread run the algorithm the application freezes for the time of execution. I have looked through the

Problems using ''select''

Partial Naming Madness

Each foo partial makes use of a variable inside called ''foo'' (and can get foo.id etc). After all the partials are loaded, I need to :update a div corresponding to one of the partials (ie re-load the

Managing sensitive strings with puppet
