generate machine code directly via LLVM API -


with following code, can generate llvm bitcode file module:

llvm::module * module;  // fill module code module = ...;  std::error_code ec; llvm::raw_fd_ostream out("anonymous.bc", ec, llvm::sys::fs::f_none);  llvm::writebitcodetofile(module, out);

i can use bitcode file generate executable machine code file, e.g.:

clang -o anonymous anonymous.bc

alternatively:

llc anonymous.bc gcc -o anonymous anonymous.s

my question is: can generate machine code directly in c++ llvm api without first needing write bitcode file?

i looking either a code example or @ least starting points in llvm api, e.g. classes use, nudging me in right direction might enough.

take @ llc tool source, spcifically compilemodule() function. in short, creates target, sets options via targetoptions, uses addpassestoemitfile() , asks passmanager perform planned tasks.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
