Peter Maydell 5c32be5baf tcg/sparc: Zero extend address argument to ld/st helpers The C store helper functions take the address argument as a target_ulong type; if this is 32 bit but the host is 64 bit then the SPARC calling convention requires that the caller must zero extend the value. We weren't doing this, which meant we could pass values to the caller with high bits set and QEMU would crash if it was compiled with optimizations. In particular, the i386 BIOS would not start.

Peter Maydell 5c32be5baf tcg/sparc: Zero extend address argument to ld/st helpers

The C store helper functions take the address argument as a
target_ulong type; if this is 32 bit but the host is 64 bit
then the SPARC calling convention requires that the caller
must zero extend the value. We weren't doing this, which
meant we could pass values to the caller with high bits set
and QEMU would crash if it was compiled with optimizations.
In particular, the i386 BIOS would not start.
