( [id://3333]=superdoc: print w/replies, xml ) Need Help??

chromatic,

The current documentation for LLVM has an example of using JIT with an existing 'C' program, without a custom front-end. I couldn't get it to work using the sample, so maybe it's not in version 3.1 - 3.2. And maybe it's a mis-print!

I joined the LLVMdev list and asked that question.

If and when I get an answer, I'll post either 'success' or 'failure' or whatever, but 15% improvement is nice. I'm not endorsing anything, since this is more of a learning exercise for me.

IBM 'xlc' is way faster on p-series machines than 'GCC', but I gave up long ago trying to get 'C' code that was designed and tested with 'GCC' to get compiled with 'xlc'! If it's my code, then I'll go with 'xlc'.

To generate a Perl 5.16.0 took half the time with 'clang' as it was to generate it with 'GCC'. And 100% of the Perl test-cases worked.

For that, I'm impressed.

Thank you

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
