The issue arises when FPU is enabled by writing to CPACR and the VFP code is in the same TB. QEMU generates a "v7M NOCP UsageFault". + +I recall that Translation Blocks (TB) are used by QEMU for efficient execution, grouping instructions together. If the write to CPACR and subsequent VFP operations are within the same TB, there might be an issue with how the state changes are handled across different instruction streams. + +The problem seems related to how the CPU context is managed during translation. Since VFP uses FPU registers and the CPACR controls access to them, if the write isn't properly reflected in the same TB, it's likely a problem in the way QEMU handles the switch between non-VFP and VFP instructions within the same block. + +I think this might fall under 'mistranslation' because it's about how the semantics are mapped from the source (CPU) to the target (IR), especially when switching contexts like enabling FPU. Alternatively, it could be related to the assembly lowering if there's an issue in generating the right instructions for VFP. + +But considering that the problem is within the same TB and involves state changes (CPACR write affecting VFP code), it seems more about how the translation block handles context switches or feature usage. Since 'mistranslation' covers incorrect semantic mapping, this fits as it's an issue where the expected behavior isn't happening when moving from a non-VFP instruction to a VFP one in the same TB. +</think> + +The bug report involves issues with VFP code not recognizing changes in CPACR within the same translation block, leading to UsageFaults.
