Let me try to figure out what's going on here. + +The user is using QEMU version 4.0.0-rc3 and tried to bootstrap GCC trunk under an arm64 Gentoo installation. They used the `-cpu cortex-a57` option and compiled QEMU with gcc version 5.5.0. When they ran the executable `vldX.c`, which was compiled at different optimization levels, it caused QEMU to crash. + +The error messages are from two different runs: one with `d2.exe` leading to an assertion failure in `tcg_gen_code` and another with `s2.exe` causing a failure in `set_jmp_reset_offset`. + +Looking deeper, the user suspects that this has to do with the TCG (Translation Coupled Guest) code generation. They mentioned that when the number of operations exceeds a certain threshold, the generated code might overflow or not fit within expected boundaries. Specifically, they refer to comments about whether `tcg_ctx->nb_ops < 4000` implies the buffer can fit in a 16-bit signed integer. + +They tried modifying the TCG code to bail out when an assertion fails by returning -1 instead of crashing. However, this didn't fix the issue; instead, QEMU just hangs because it keeps re-entering the same loop without properly handling the return value. + +So, classifying this bug: The error occurs during the generation of machine code from TCG intermediate representation (IR). It's related to how translation blocks are handled and whether they fit within certain size constraints. This seems to be a problem in the translation process, not with user-mode assembly or other categories like graphics or network. + +The key here is that it's an issue with the way QEMU translates instructions for the target architecture (ARM64 in this case), which falls under the 'mistranslation' category because it's about incorrect semantic mapping leading to assertion failures during code generation. +</think> + +mistranslation \ No newline at end of file |
