Detailed Description

Contains code macros for the processor floating-point load/store instructions.

Based on ARM chapter 4.8.

X-1.13 Brian Wheeler 27-FEB-2008 Avoid compiler warnings.

X-1.12 Camiel Vanderhoeven 06-FEB-2008 Check for FPEN in old floating point code.

X-1.11 Camiel Vanderhoeven 05-FEB-2008 Only use new floating-point code when HAVE_NEW_FP has been defined.

X-1.10 Camiel Vanderhoeven 28-JAN-2008 Better floating-point exception handling.

X-1.9 Camiel Vanderhoeven 25-JAN-2008 Trap on unalogned memory access. The previous implementation where unaligned accesses were silently allowed could go wrong when page boundaries are crossed.

X-1.8 Camiel Vanderhoeven 21-JAN-2008 Implement new floating-point code.

X-1.7 Camiel Vanderhoeven 2-DEC-2007 Changed the way translation buffers work.

X-1.6 Camiel Vanderhoeven 08-NOV-2007 Restructured conversion routines.

X-1.5 Eduardo Marcelo Serrat 31-OCT-2007 Fixed conversion routines.

X-1.4 Camiel Vanderhoeven 11-APR-2007 Moved all data that should be saved to a state file to a structure "state".

X-1.3 Camiel Vanderhoeven 30-MAR-2007 Added old changelog comments.

X-1.2 Camiel Vanderhoeven 13-MAR-2007 Basic floating point support added.

X-1.1 Camiel Vanderhoeven 18-FEB-2007 File created. Contains code previously found in AlphaCPU.h
