[Qemu-devel] [PATCH v2 2/3] ARM: Set softfloat cumulative exc flags from correct FPSCR bits |
Date: |
Thu, 6 Jan 2011 19:37:54 +0000 |
When handling a write to the ARM FPSCR, set the softfloat cumulative
exception flags from the cumulative flags in the FPSCR, not the
exception-enable bits. Also don't apply a mask: vfp_exceptbits_to_host
will only look at the correct bits anyway.
