The user is reporting an issue with multithreading not working correctly under QEMU's user mode for SH4 architecture. They mentioned that their program works on other architectures like alpha, armelhf, aarch64, and powerpc64le but fails on SH4. + +Looking at the provided stack traces from gdb, I notice that the issue seems to be related to futex operations in QEMU's syscall handling. Futexes are used for inter-thread synchronization, so if they're not working properly, it can cause hangs or deadlocks in multithreaded programs. + +The problem occurs when using pthread_join, which is part of the threading API. Since this is happening under user-mode emulation in QEMU, it's likely a bug in how QEMU handles system calls related to threads on SH4. The fact that other architectures work suggests that the issue is specific to SH4's implementation. + +The possible categories include 'mistranslation' which relates to incorrect semantic mapping from source architecture to IR/target. However, this issue seems more about how QEMU handles user-mode threading, particularly in its syscall layer for SH4. The error occurs during futex operations, which are handled in the syscall.c file, as seen in the stack traces. + +Given that the problem is with multithreading under user mode and involves incorrect handling of system calls related to threads (futex), it's likely a bug in the translation or emulation layer specific to SH4. Therefore, the most appropriate category seems to be 'mistranslation' since it pertains to how QEMU maps the target architecture's threading model onto its own IR or user-mode environment. +</think> + +mistranslation \ No newline at end of file |
