It sounds to me like you just need a way to handle C++ exceptions inside of the C++ code and then rethrow so that the JIT's caller can do its thing. (Right?) Right. The call sequence is: my_lib(1) -> JIT_code -> C_thunk -> my_lib(2) The JIT code creates Functions that create C++ objects on their stacks (by using alloca instructions then calling a C thunk that calls the C++ object's constructor via placement new). If an exception is thrown in my_lib(2), then somewhere betwee...

Hi I''m building a small library to use in my Rails app which interacts with a 3rd party API. It fetches artists and tracks. So I have: lib/my_lib.rb lib/my_lib/artist.rb lib/my_lib/track.rb To get an artist I do artist = MyLib::Artist.find("Oasis") Which returns an instance of Artist if it finds (via 3rd party API) it or nil otherwise. Then I can call artist.tracks which fetches all available tracks at the 3rd party and returns...

Hello, I am getting the following error while trying to build a benchmark with a custom function pass: clang -Xclang -fopenmp=libomp -Xclang -load -Xclang my_lib.so file.c error: unknown argument: '-fopenmp=libomp' If I use this instead: clang -Xclang -fopenmp=libomp -Xclang -load -Xclang my_lib.so file.c I get the error: fatal error: 'omp.h' file not found I am not sure where the problem is, especially since I have used OpenMP appl...

...e) for some load and store instructions. The functions exist in a library file. I found that the approach works for the example in the link: http://llvm.org/docs/GoldPlugin.html $ llvm-gcc -flto a.c -c -o a.o $ ar q a.a a.o $ llvm-gcc b.c -c -o b.o $ llvm-gcc -use-gold-plugin a.a b.o -L<path_to_my_lib> -l<my_lib> -o main I also found that I can compile large programs (apache and mysql) with gold plugin. Here is the command: $ export CC="llvm-gcc -use-gold-plugin"; export CXX="llvm-g++ -use-gold-plugin"; export RANLIB=/bin/true; export CFLAGS="-O4"; $ ./con...

Do I need to do anything special to access classes in RAILS_ROOT/lib from a worker? Maybe: require File.dirname(__FILE__) + ''../my_lib.rb'' or does it do that automatically like a controller does? Also if I write a unit test for a worker that is accessing AR, is there anything special needed to be done to access fixtures etc to test it? Thanks -- Jim Morris, http://blog.wolfman.com

I am testing my app on a shared host account on Site5. The app is in development mode and all changes for the most part take place immediately. The only exception are the classes that I have developed and placed in my lib/ directory. I can make a change to my class, run my app, have it behave in the previous manner, go to bed, come back the next morning, and the changes will have taken

R version R-1.2.0 gdb version GNU gdb 4.18 gcc version 2.95.2 Linux version SUSE 7.0 I tried to recompile without the O2 option, but to no avail. I also tried both R INSTALL <my_lib> and doing R SHLIB <my_file.c> and then manually loading the .so file.

Im writing a module in the lib directory. If I change the module, the changes are not visible to the application when i releod the web page (i am in the development evironment). I must restart the web server (WEBrick) and so i see the changes... but I lost more time. How can I reload the module in the dirictory lib, without reload WEBrick? Thanks so much --Reis -- Posted via
