asmgcc assertion error in lang-smalltalk
by Lars Wassermann July 21, 2013

July 21, 2013

Hello, in the project lang-smalltalk, we have a problem we don't know where exactly the source may be. When running the VM with jit, we get: PyPy assertion failed at rpython_memory_gctransform_asmgcroot.c:583: in pypy_g_locate_caller_based_on_retaddr: found a stack frame that does not belong anywhere I know, bug in asmgcc Aborted (core dumped) When running without jit, everything works fine. Is the fact that the error only occurs when using the JIT a hint that the bug may not be in asmgcc? … [View More]

Pypy translation fails on MIPS (without JIT)
by Alexis BRENON July 18, 2013

July 18, 2013

Hi everyone, As someones know, I'm working for a company (as an internship) on the MIPS port of Pypy. I started the JIT backend but not finished and for the moment I try to translate Pypy without JIT (because JIT isn't finished). I try to translate it directly on the target, even if it will take very very long time. But for the moment I only try to compile a small Rpython snippet : def main(args): print "Hello World" return 0 def target(*args): return main, … [View More]

PyPy doesn't make code written in C faster
by Armin Rigo July 18, 2013

July 18, 2013

Hi all, Some people learn about PyPy, and the first program they try to measure speed with is something like this: def factorial(n): res = 1 for i in range(1, n + 1): res *= i return res print factorial(25000) It may not be completely obvious a priori, but this is as bogus as it gets. This is by now only 50% slower in PyPy than in CPython thanks to efforts from various people. The issue is of course that it's an algo which, in CPython or in PyPy, spends most of its time … [View More]

ndarray-subtype branch looking for review
by Matti Picus July 17, 2013

July 17, 2013

The ndarray-branch passes tests both translated and untranslated. I ran it through the numpy test suite as well, specifically the matrix class tests, and it seems to pass them. Would anyone like to review, or should I just go ahead and merge? Specifically, I may have missed some w_ prefixes on app-level instances, or may not have tested all the code paths, and I had to hack the FakeSpace in compile.py to allow subclassing. Matti
