C This runs well on A15 but very poorly on A9. By scheduling loads and adds
C it is possible to get good A9 performance as well, but at the cost of using
C many more (callee-saves) registers.
C This is armv5 code, optimized for the armv7a cpu A15. Its location in the
C GMP file structure might be misleading.

COMMENT @%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
NCUObjMessageCheckAndSend
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
SYNOPSIS: Send a message to a ui object of the NavControl
provided the object has been built.
CALLED BY: UTILITY
PASS: ^lbx:si - OD of object
ds - fixupable segment
ax - message to send
values for message (cx, dx, bp)
RETURN: ds - fixed up
DESTROYED: none
PSEUDO CODE/STRATEGY:
Send the passed message and parameters to
the object so long as bx is not null. If
bx = null, then we're trying to send a
message to some ui object that isn't built
yet (and may never be).

; LLCGRP - Core GW-BASIC Graphics Interface
;
; Copyright <C> 1986, Microsoft Corporation
;
;Purpose:
; This module contains support for graphics functions required
; by programs that may not use graphics drawing statements.
; Some non-graphic statements (such as CLS) require some graphic
; support. Routines directly supporting only graphics drawing
; statements are placed in LLAGRP to improve runtime granularity
; and reduce the size of programs not directly using graphics.
;
; Routines in this module are mode-independent in one or more of the
; following ways:
; 1) no device-dependent interaction,
; 2) table driven through mode-dependent data vectors, or
; 3) calls mode-dependent routines through function vectors.
;
; Mode-dependent graphics functions and initializers for vectors
; are segregated in separate modules for better granularity.

;#***************************************************************************
; Mode-dependent data and function vectors
;
; This data is filled by B$InitModeData from matching tables in the mode-
; dependent modules. All are created using the same macro set to insure
; consistency in their structure and to provide a central point (the macros)
; for modifying that structure. The "mEnd" macro actually builds the table.
; Specifying TRUE for its "def" (third) parameter causes it to also create
; PUBLIC names (prefixed with "b$") for each data item. This also
; creates the GraphVectStart LABEL and GraphVectCnt ABSOLUTE used by
; B$InitModeData to reset the graphics function vectors for text modes.
;
; Refer to GRMAC.INC for more details on the actual structure and the
; variables provided. To aid in the textual search for these names,
; omit the "b$" in the search. This will locate all of the macro-generated
; sources for the data item in all the modules. (e.g.: searching for
; "ScreenMode" instead of "b$ScreenMode" will find all of the "mScreenMode"
; macro invocations.)
;
;This data table is pre-initialized to resemble a 40-column (worst case)

;b$ScreenMode - Current Basic Screen Mode
;OEM-interface routine (variable)
;
;Purpose:
; This variable contains the BASIC mode number of the current
; screen mode. This is the number as given in the SCREEN
; statement, not the BIOS mode number.
;
;Allocated:
; b$ScreenMode is a BYTE value allocated in _DATA by the OEM.
;
;Values:
; This variable is initially set to 0 for a worst case scenario
; when an error message has to be printed before the screen is
; initialized. After initialization, it may take on the value
; of any legal screen mode (0-2, 7-13 if all possible modes are
; supported).
;
;Initially Set:
; b$ScreenMode is statically initialized to 0.
;
;Modified By:
; This variable is only modified by the OEM-Dependent routines.
; It should be updated when the screen is initialized, and when
; a SCREEN statement is given.
;
;Used By:
; This routine is used by the OEM-Dependent code to keep track
; of which screen mode is current. It is used by the OEM-Independent
; Code to determine if a graphics mode is in effect.
; (b$ScreenMode = 0 <=> non graphics mode)

; b$PalSet - Set entire palette from an array
;OEM-interface routine
;
;Purpose:
; Set the entire palette from an array specified by the user. Each

; the current index of the array. A color value of
; of -1 indicates the entry should be left alone. All entries are
; verified before any are set and are also translated, as needed.
; Verification and Translation are discussed in b$PalTrans (a non
; OEM interface routine) and b$PalPut.
;
; Special consideration must be made for the number of bytes per
; element in the array. Also, if there are not enough elements in
; the array to fill the palette, the return with PSW.C set for

;
; The VIEW statement is handled primarily in the OEM independent

; the internal representation may be too slow to do repeatedly.
; Thus, for each row of a region that is going to be painted
; [b$PaintBound] is called. This routine should set up conditions
; so that [b$ChkDownC], [b$ChkUpc], [b$ScanR], and [b$ScanL]
; can do fast tests for detecting the edges of the viewport.

# NOTE: Comments added and expanded by Neal Wagner, April 4, 1999

# Organization and Design_, Morgan Kaufmann.)
#
# INTERRUPT HANDLING IN MIPS:
# Coprocessor 0 has extra registers useful in handling exceptions
# There are four useful coprocessor 0 registers:
#-------------------------------------------------------------------|
# REG NAME | NUMBER | USAGE |
#-------------------------------------------------------------------|
# BadVAddr | 8 | Memory addr at which addr exception occurred |
# Status | 12 | Interrupt mask and enable bits |
# Cause | 13 | Exception type and pending interrupt bits |
# EPC | 14 | Address of instruction that caused exception |
#-----------|--------|----------------------------------------------|
# Details:
# Status register: has an interrupt mask with a bit for each of
# five interrupt levels. If a bit is one, interrupts at that
# level are allowed. If a bit is zero, interrupts at that level
# are disabled. The low order 6 bits of the Status register
# implement a three-level stack for the "kernel/user" and
# "interrupt enable" bits. The "kernel/user" bit is 0 if the
# program was running in the kernel when the interrupt occurred
# and 1 if it was in user mode. If the "interrupt enable" bit is 1,
# interrupts are allowed. If it is 0, they are disabled. At an
# interrupt, these six bits are shifted left by two bits.
# Cause register: The value in bits 2-5 of the Cause register
# describes the particular type of exception. The error messages
# below describe these values. Thus a 7 in bits 2-5 corresponds
# to message __e7_ below, or a "bad address in data/stack read".
#
# There are special machine instructions for accessing these
# coprocessor 0 registers:
# mfc0 Rdest, CPsrc: "move from coprocessor 0" moves data
# from the special coprocessor 0 register CPsrc into the
# general purpose register Rdest.
# mtc0 Rsrc, CPdest: "move to coprocessor 0" moves data
# from the general purpose register Rsrc into the special
# coprocessor 0 register CPdest.
# (There are also coprocessor load and store instructions.)
#
# ACTIONS BY THE TRAP HANDLER CODE BELOW:
# Branch to address 0x80000180 and execute handler there:
# 1. Save $a0 and $v0 in s0 and s1 and $at in $k1.
# 2. Move Cause into register $k0.
# 3. Do action such as print an error message.
# 4. Increment EPC value so offending instruction is skipped after
# return from exception.
# 5. Restore $a0, $v0, and $at.
# 6. Clear the Cause register and re-enable interrupts in the Status
# register.
# 6. Execute "eret" instruction to return execution to the instruction
# at EPC.
