Typical page size will still be 64KB, so a 4KB guard would be rounded up to 64KB. An ILP32 system with 64KB pages could create ~30000 threads per process. Does that make it unusable?... and this is already configurable via pthread_attr_setguardsize(), so you *could* tune a system to have smaller guards against the recommendation of the runtime authors?Sure, if you recompile your application. That's not really a solution IMHO.You've got to do that already in order to run it on ILP32 - there isn't exactly a large amount of existing ILP32 binaries around, let alone ones that need more than 30000 threads per process.
I wasn't talking about aarch64 ILP32, and I suspect neither was Carlos.In my world, if you still have 32-bit binaries, it's because you lost the sources or the tools or knowledge to build them at some point.
Thanks, Florian
