Hi, the file rpython/translator/c/src/stack.h defines MAX_STACK_SIZE. PPC has a bigger limit than e.g. x86. I experienced that on s390x there is as well a higher consumption of memory for stack frames (they are variable sized with a pretty high minimum limit (160 bytes) by the ABI).
I have two questions: 1) The OS (i.e. linux) defines a stack limit (ulimit -s), does pypy overwrite this value with MAX_STACK_SIZE? 2) How would I determine which size is best for s390x? Or how did we come up with 768kb for x86, and 2.8mb for ppc? Cheers, Richard
