Detailed Description

Contains some macro definitions and some inline functions for the Alpha CPU.

cpu_defs.h,v 1.13 2008/03/14 15:30:52 iamcamiel Exp

X-1.12 Camiel Vanderhoeven 14-MAR-2008 1. More meaningful exceptions replace throwing (int) 1. 2. U64 macro replaces X64 macro.

X-1.11 Camiel Vanderhoeven 05-MAR-2008 Multi-threading version.

X-1.10 Camiel Vanderhoeven 08-FEB-2008 Show originating device name on memory errors.

X-1.9 Camiel Vanderhoeven 05-FEB-2008 Bug description added.

X-1.8 Camiel Vanderhoeven 01-FEB-2008 Disable unaligned access check alltogether; it doesn't work properly for some reason.

X-1.7 Camiel Vanderhoeven 01-FEB-2008 Avoid unnecessary shift-operations to calculate constant values.

X-1.6 Camiel Vanderhoeven 28-JAN-2008 Better floating-point exception handling.

X-1.5 Brian Wheeler 26-JAN-2008 Make file end in newline.

X-1.4 Camiel Vanderhoeven 26-JAN-2008 Do unaligned trap only when a page boundary is crossed. Something is causing alignment traps in the SRM console, with the DAT bit set to false, and no OS handler in place. Also, when OpenVMS boots there are alignment traps that shouldn't happen. None of these cross page boundaries, so we're safe for now.

X-1.3 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-1.2 Camiel Vanderhoeven 22-JAN-2008 Added RA, RAV style macro's for integer registers.

X-1.1 Camiel Vanderhoeven 21-JAN-2008 File created. Contains code pulled from various older source files, and some floating-point definitions based upon the SIMH Alpha pre- implementation, which is Copyright (c) 2003, Robert M Supnik.

Bug:

Fix unaligned access traps.

cSystem->ReadMem(phys_address, size, this)

Normal variant of read action In reality, these would generate an alignment trap, and the exception handler would put things straight.

Instead, to speed things up, we'll just perform the read as requested using the unaligned address.

#define READ_PHYS_NT

cSystem->ReadMem(ALIGN_PHYS((size) / 8), size, this)

NO-TRAP (NT) variants of read action.

This is used for HW_LD, where alignment traps are inhibited. We'll align the adress and read using the aligned address.
