Hi everyone, llvm is great! But there is one exception ;) llvm components are generally fast, but instruction selection is slooow. Let me explain. I am developing a toolkit for building virtual machines which can automatically generate a JIT compiler using the interpreter specification. llvm does the hard work of machine code generation. (Thanks to you all) I discovered that JIT compilation is

Hi! I'm developing a register allocator and need it to be available as an option for llc tool. I used to edit /lib/CodeGen/Passes.cpp for this aim but after yesterday's update these options are defined somewhere else and I can't find the place. Thanks for your help.

summary: I can display a lon-lat map on a lattice::layerplot, and I can display a Lambert conformal conic (LCC) map on a spam::image, but I can't display an LCC map on a lattice::layerplot. Example follows. What am I doing wrong? details: I've been using `lattice` (via `rasterVis`) successfully to display global atmospheric data, which works well enough (though I am definitely intrigued

I'm trying to get the Syncrosoft License Control Center to run under wine. for some reason it can only load MFC42.DLL and MSVCRT.DLL if I put 'sudo' on the command line: [paul@localhost LCC]$ wine LCC.exe err:module:import_dll Library MFC42.DLL (which is needed by L"C:\\Program Files\\Syncrosoft\\LCC\\LCC.exe") not found err:module:import_dll Library MSVCRT.dll (which is

Refactor this code to use guestfs_int_split_string function which slightly simplifies it.

I've read something about this problem, but I don't know how can i avoid this problem. Why the order of the factors give different results? I suppose it's because the order of the factors, i've just changed "lcc" from the first position to the last in the model, and the significance change completely >

I haven''t been able to find any discussion about this. It looks as if Selector.matchElements is broken (which means that Selector.findElement, Element.down(elt, cssselector) dont work properly. What I''m seeing is that (line 3310) the Selector.findElements is not called with the root node of the node you are wishing to find elements under (its not called with a parameter at all)

How do I get the keyboard layout selector in gdm login for 6.3? I have language selector but no keyboard layout selector. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

Hi there first of all, many thanks to some people out there for their advice on building LLVM on Cygwin (this would be Aaron Gray, Reid Spencer, Tanya and Chris Lattner i suppose). LLVM 2.1 seems to build in debug mode on my "old" Cygwin (1.5.15). At least everything except tblgen is build. For tblgen i use the supplied mingw binaries, many thanks for that! I would like now to ask you

Here http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector llvm.eh.selector is declared like this: i32 %llvm.eh.selector <http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector>(i8*, i8*, i8*, ...) But when clang++ (rev.121360) writes the module with exceptions, it writes it out like this: declare i32 @llvm.eh.selector(i8*, i8*, ...) nounwind Why there is such descrepancy?

Funny I remember that code (DwarfEHPrepare), wondering at the time why it was doing this. Thanks for your response, as I can now stop trying figure out how I am introducing this error, and more importantly now will be able to go back to DwarfEHPrepare, and understand it better knowing one of its purposes. However the result of my tests indicates that the underlying register used by the

Hi Garrison, > I hacked together a version of DwarfEHPrepare.cpp which tries to deal with the ordering of llvm.eh.exception and llvm.eh.selector. > The hacked is contained within the attached patch. it looks like you tried to copy the code for eh.exception. There are two problems with this: (1) the eh.exception code really needs to be rewritten to make use of the new SSAUpdator (then all

Just a quick heads up that Sylvain Zimmer has posted a performance upgrade for Prototype''s $$ selector, making the function up to 20 times faster. This could be just the thing I''ve been looking for recently as a site I''m currently developing makes heavy usage of that $$ selector and I have noticed that this can lead to a noticeable lag on page load. See

hiya, i want the selector that would return a <tr> of a table if any td contains some text, so i can use it in click_link_within e.g. When I click the "show" link within the row containing "user at example.com" When /^I click the "(.+)" link within the row containing "(.+)"$/ do | link, text| selector = ?? click_link_within selector, link

hi, i found a problem in LLVM regarding the matching of 'Constant' nodes in the instruction selector. the testcase is for x86, but similar testcases for the other architectures (e.g. ppc) should be easy to create. i'm using the llvm-gcc 2.0 prerelease binary package. here is the testcase: int foo(int bar) { asm("movl %1, %0" : "=r"(bar) : "i"(5));

Hi, I''m calling on those with Prototype/CSS selector foo to help with a somewhat tricky issue. I have a tree structure where each item is hierarchical. This is used to manage software components. Think of the case where you''re installing a piece of software, and want to customize which packages are installed: [ ] Internet [ ] Email [ ] Thunderbird [ ]

So unDAGing is applied by the instruction scheduler. At which points in the compilation flow is the instruction scheduler run (i'm

I accidentally ran into a JIT scenario where a call instruction, executing an external non-generated C function, executed between a llvm.eh.exception and a llvm.eh.selector instruction would clobber the register (register index __builtin_eh_return_data_regno(1)), used by the return value of llvm.eh.selector. The behavior of the call depends on the function called even though none of the
