Re: [pypy-dev] [pypy-commit] pypy default: (arigo, bivab) implement longlong2float and float2longlong in a way that is more close to the C standard. On ARM/32bit this code was causing a reodering of instructions that filled one of the two words with garbage

Compiling PyPy 1.5 fails on Slackware 13.37
by Audrius Kažukauskas June 6, 2011

June 6, 2011

Hi, I've reported this on #pypy yesterday, but I thought this might be a better place for this kind of information. I've tried to build PyPy 1.5 from source on Slackware 13.37 (32-bit LXC container, while the host and kernel are 64-bit; both systems Slackware) and got an exception[0] in the last stage of the build process (compilation). [0] http://paste.pocoo.org/show/387121/ Here are some bits of information about the system used: gcc 4.5.2, glibc 2.13. If you need anything else, I'll be … [View More]

Re: [pypy-dev] JIT for scripts

Great to hear about PHP. I hope you don't mind a question. Were you able to reuse the Python object model for your PHP interpreter, or is the PHP object model too different? Laura

JIT for scripts
by Alex Şuhan June 1, 2011

June 1, 2011

Hello. PyPy works great for our PHP JIT interpreter, with nice speedups for most of the processing-intensive (with loops), shootout-ish scripts. However, I feel that short scripts running often could benefit from tracing as well if we make the interpreter „persistent” -- that is, keep all the scripts in memory, create a jump (with a variable target) for dispatching the requested script and a backward jump (to the fore-mentioned dispatch jump) at the end of each script.
