The user provided a sample Go program and backtraces showing crashes in QEMU environments, particularly pointing to issues with atomics in the runtime. They mentioned that after fixing another bug (#1738545), Go works on qemu-arm but not on qemu-sh4. + +Looking at the error messages, it seems the problem is related to how pointers are aligned. The 'runtime.work' struct isn't 8-aligned, causing a panic when atomic operations try to access it. This suggests that the compiler (gccgo) isn't generating correctly aligned code for SH4 architecture in QEMU. + +The user suspects this is a bug in gccgo's code generation rather than QEMU itself. They found that the 'runtime.work' struct is placed at a non-8-aligned address, which violates Go's memory layout requirements. Therefore, the issue lies with how the compiler handles alignment for SH4 targets. + +Since the problem stems from incorrect pointer alignment due to the compiler, and not from QEMU's emulation or other areas like device drivers or network handling, the appropriate category is 'mistranslation'. This refers to issues where the source code (in this case, the compiler) incorrectly maps the architecture-specific details into the target (SH4), leading to runtime errors. +</think> + +The bug report points to an issue with how the SH4 compiler generates code, specifically in aligning pointers correctly. The problem lies in the compiler's handling of struct alignments, which causes a crash when QEMU runs the generated binary. This is a miscalculation during compilation rather than an issue with QEMU itself. + +**Answer:** The category for this bug report is **mistranslation**. \ No newline at end of file |
