QEMU uses code retranslation to restore the CPU state when an exception happens. For it to work the retranslation must not modify the generated code. This is what is currently implemented in ARM TCG. However on CPU that don't have icache/dcache/memory synchronised like ARM, this requirement is stronger and code retranslation must not modify the generated code "atomically", as the cache line might be flushed at any moment (interrupt, exception, task switching), even if not triggered by QEMU. The probability for this to happen is very low, and depends on cache size and associativiy, machine load, interrupts, so the symptoms are might happen randomly. This requirement is currently not followed in tcg/arm, for the load/store code, which basically has the following structure: 1) tlb access code is written 2) conditional fast path code is written 3) branch is written with a temporary target 4) slow path code is written 5) branch target is updated The cache lines corresponding to the retranslated code is not flushed after code retranslation as the generated code is supposed to be the same. However if the cache line corresponding to the branch instruction is flushed between step 3 and 5, and is not flushed again before the code is executed again, the branch target is wrong. In the guest, the symptoms are MMU page fault at a random addresses, which leads to kernel page fault or segmentation faults. The patch fixes this issue by avoiding writing the branch target until it is known, that is by writing only the branch instruction first, and later only the offset. This fixes booting linux guests on ARM hosts (tested: arm, i386, mips, mipsel, sh4, sparc). Acked-by: NEdgar E.

The code in the linux-user ARM nwfpe emulation was incorrectly checking only for quiet NaNs when it should have been checking for any kind of NaN. This is probably because the code in question was taken from the Linux kernel, whose copy of the softfloat library had been modified so that float*_is_nan() returned true for all NaNs, not just quiet ones. The qemu equivalent function is float*_is_any_nan(), so use that. NB that this code is really obsolete since nobody uses FPE for actual arithmetic now; this is just cleanup following the recent renaming of the NaN related functions.

Wire up the new softfloat support for flushing input denormals to zero on ARM. The FPSCR FZ bit enables flush-to-zero for both inputs and outputs, but the reporting of when inputs are flushed to zero is via a separate IDC bit rather than the UFC (underflow) bit used when output denormals are flushed to zero.

Add support to softfloat for flushing input denormal float32 and float64 to zero. softfloat's existing 'flush_to_zero' flag only flushes denormals to zero on output. Some CPUs need input denormals to be flushed before processing as well. Implement this, using a new status flag to enable it and a new exception status bit to indicate when it has happened. Existing CPUs should be unaffected as there is no behaviour change unless the mode is enabled.

SMMLA and SMMLS are broken on both in normal and thumb mode, that is both (different) implementations are wrong. They try to avoid a 64-bit add for the rounding, which is not trivial if you want to support both SMMLA and SMMLS with the same code. The code below uses the same implementation for both modes, using the code from the ARM manual. It also fixes the thumb decoding that was a mix between normal and thumb mode.
