/* A C compound statement to output to stdio stream STREAM the
assembler syntax for an instruction operand X. X is an RTL
expression.
CODE is a value that can be used to specify one of several ways
of printing the operand. It is used when identical operands
must be printed differently depending on the context. CODE
comes from the `%' specification that was used to request
printing of the operand. If the specification was just `%DIGIT'
then CODE is 0; if the specification was `%LTR DIGIT' then CODE
is the ASCII code for LTR.
If X is a register, this macro should print the register's name.
The names can be found in an array `reg_names' whose type is
`char *[]'. `reg_names' is initialized from `REGISTER_NAMES'.
When the machine description has a specification `%PUNCT' (a `%'
followed by a punctuation character), this macro is called with
a null pointer for X and the punctuation character for CODE.
The 1750 specific codes are:
'J' for the negative of a constant
'Q' for printing addresses in B mode syntax
'd' for the second register in a pair
't' for the third register in a triple
'b' for the bit number (using 1750 test bit convention)
'B' for the bit number of the 1's complement (for bit clear)
'w' for int - 16

This document describes the proposed ABI for the d10v.
The register calling convention is:
+-------+-----------------------+-----------------------+
| Reg. | At prologue | After epilogue |
+-------+-----------------------+-----------------------+
| R0 | Argument #1 | Return value, word 1 |
+-------+-----------------------+-----------------------+
| R1 | Argument #2 | Return value, word 2 |
+-------+-----------------------+-----------------------+
| R2 | Argument #3 | Return value, word 3 |
+-------+-----------------------+-----------------------+
| R3 | Argument #4 | Return value, word 4 |
+-------+-----------------------+-----------------------+
| R4 | Static chain if needed| Don't care |
+-------+-----------------------+-----------------------+
| R5 | Work | Don't care |
+-------+-----------------------+-----------------------+
| R6 | Work | Previous value |
+-------+-----------------------+-----------------------+
| R7 | Work | Previous value |
+-------+-----------------------+-----------------------+
| R8 | Work | Previous value |
+-------+-----------------------+-----------------------+
| R9 | Work | Previous value |
+-------+-----------------------+-----------------------+
| R10 | Work | Previous value |
+-------+-----------------------+-----------------------+
| R11 | Frame ptr if needed | Previous value |
+-------+-----------------------+-----------------------+
| R12 | Work | Don't care |
+-------+-----------------------+-----------------------+
| R13 | Return address | Don't care |
+-------+-----------------------+-----------------------+
| R14 | memory base (0) | memory base (0) |
+-------+-----------------------+-----------------------+
| R15 | Stack pointer | Previous value |
+-------+-----------------------+-----------------------+
| A0 | Work | Previous value |
+-------+-----------------------+-----------------------+
| A1 | Work | Previous value |
+-------+-----------------------+-----------------------+
The 'int' type is 16 bits, unless the -mint32 switch is used. The 'long' type
is always 32 bits, the 'short' type is always 16 bits, and pointers are 16
bits.
The 'double' type is treated as 'float' and uses 32-bits unless the -mdouble64
switch is used. The long double type still uses 64 bits.
If more than 4 words of arguments are passed, they are passed on the stack.
The GCC compiler will omit the frame pointer for all functions except those
that dynamically grow the stack frame (ie, the GNU extensions of variable sized
arrays or calls to alloca). The GCC compiler will always eliminate the
pseudo argument pointer the compiler synthesizes in favor of the stack or frame
pointer.
The GCC compiler only passes the static chain when calling nested functions,
which is a GNU extension.
The stack starts at high memory and descends downward. The heap starts at the
end of the bss section and ascends upward. The stack is assumed to be aligned
to a word boundary.
Register r14 will be used as the index register in accessing global/static
variables if no index register is used. The crt0 that we provide will place a
zero in it, and the compiler will expect that.
The varargs/stdarg support defines the va_list type as follows:
typedef struct __va_list_tag {
short *__va_arg_ptr; /* start of the register save area */
int __va_arg_num; /* argument number */
} va_list[1];
It is an array so that passing it to vprintf and friends passes just a pointer
to the structure. Calls to varargs/stdarg functions push the four words
corresponding to the first four arguments on the stack immediately before
adjusting the stack pointer any further.
The stack frame when a function is called looks like:
high | .... |
+-------------------------------+
| Argument word #8 |
+-------------------------------+
| Argument word #7 |
+-------------------------------+
| Argument word #6 |
+-------------------------------+
| Argument word #5 |
low SP----> +-------------------------------+
After the prologue is executed, the stack frame will look like:
high | .... |
+-------------------------------+
| Argument word #8 |
+-------------------------------+
| Argument word #7 |
+-------------------------------+
| Argument word #6 |
+-------------------------------+
| Argument word #5 |
Prev sp +-------------------------------+
| |
| Save for arguments 1..4 if |
| the func. uses stdarg/varargs |
| |
+-------------------------------+
| |
| Local variables |
| |
+-------------------------------+
| |
| Save area for preserved regs |
| |
+-------------------------------+
| |
| alloca space if used |
| |
+-------------------------------+
| |
| Space for outgoing arguments |
| |
low SP----> +-------------------------------+

CYGNUS LOCAL -- meissner/d30v
-*- Text -*-
This document describes the proposed ABI for the D30V processor. This is
revision 2 of the document.
Revision history:
Revision 1:
Original revision of this document.
Revision 2:
Done after consultation with Mitsubshi about the calling sequence.
This revision now reduces the number of registers the compiler will not
touch from 18 registers down to 8.
Register 1 is now a normal temporary register, since mvfacc rx,ay,32 is
legal.
Arguments greater than 4 bytes must be passed in an even register or at
a double word alignment.
The va_list type is a structure, not a char *.
The stack must be aligned to 8 byte boundary. Doubles and long longs
must also be aligned to 8 byte boundaries.
System calls are specified via trap 31.
Revision 3:
I added discussion about compiler switches.
Register usage:
===============
Registers Call Status Usage
--------- ----------- -----
R0 hardware Hardwired to 0
R1 volatile temp
R2 volatile Arg 1 and main return value.
R3 volatile Arg 2 and low bits of 64 bit returns
R4 - R17 volatile Args 3-16
R18 volatile Static chain if used
R19 - R25 volatile temps
R26 - R33 saved Reserved for user use
R34 - R60 saved Registers preserved across calls
R61 saved Frame pointer if needed.
R62 saved Return address pointer (hardware)
R63 saved Stack pointer
CR0 - CR3 hardware {normal,backup} {psw,pc}
CR4 - CR6 hardware Reserved for future use
CR7 - CR9 volatile Repeat count, addresses
CR10 - CR11 saved Modulo start/end
CR12 - CR14 hardware Reserved for future use
CR15 - CR17 hardware Interrupt support
F0 - F1 volatile Execution flags
F2 - F3 volatile General flags
F4 - F7 volatile Special purpose flags
A0 volatile Accumulator
A1 saved Accumulator
Notes on the register usage:
============================
1) R61 will hold the frame pointer if it is needed. Normally the frame
pointer will not be needed, in which case this will become another
saved register.
2) Repeat instructions and delayed branches cannot cross call boundaries.
Similarly, all flags are assumed to not be preserved across calls.
3) Since so many registers are available, I reserved 8 registers (r26-r33)
for the user to use for any purpose (global variables, interrupt
routines, thread pointer, etc.). These registers will not be used by
the compiler for any purpose.
4) One of the two accumulators is saved across calls.
5) Doubles and long longs will only be allocated to even/odd register
pairs to allow use of the ld2w/st2w instructions.
Miscellaneous call information:
===============================
1) Structures are passed in registers, rounding them up to word
boundaries.
2) Any argument that is greater than word size (4 bytes) must be aligned
to a double word boundary and/or start in an even register. The
intention here is to be able to use the ld2w/st2w instructions for
moving doubles and long longs.
3) Variable argument functions are called with the same calling sequence
as non-variable argument functions. When called, a variable argument
function first saves the 16 registers (R2 - R17) used for passing
arguments. The va_list type is a structure. The first element of the
structure is a pointer to the first word saved on the stack, and the
second element is a number that gives which argument number is being
processed.
4) Word and double word sized structures/unions are returned in registers,
other functions returning structures expect a temporary area address to
be passed as the first argument.
The stack frame when a function is called looks like:
high | .... |
+-------------------------------+
| Argument word #20 |
+-------------------------------+
| Argument word #19 |
+-------------------------------+
| Argument word #18 |
+-------------------------------+
| Argument word #17 |
low SP----> +-------------------------------+
After the prologue is executed, the stack frame will look like:
high | .... |
+-------------------------------+
| Argument word #20 |
+-------------------------------+
| Argument word #19 |
+-------------------------------+
| Argument word #18 |
+-------------------------------+
| Argument word #17 |
Prev sp +-------------------------------+
| |
| Save for arguments 1..16 if |
| the func. uses stdarg/varargs |
| |
+-------------------------------+
| |
| Save area for preserved regs |
| |
+-------------------------------+
| |
| Local variables |
| |
+-------------------------------+
| |
| alloca space if used |
| |
+-------------------------------+
| |
| Space for outgoing arguments |
| |
low SP----> +-------------------------------+
System Calls
============
System calls will be done using "TRAP 31". Input arguments will be in R2 - R5,
and the system call number will be in R6. Return values from the system call
will be in R2. Negative values of the return indicate the system call failed,
and the value is the negative of the error code. Here are the assigned system
call numbers (value in R6):
exit 1
open 2
close 3
read 4
write 5
lseek 6
unlink 7
getpid 8
kill 9
fstat 10
(11 is reserved for sbrk)
argvlen 12
argv 13
chdir 14
stat 15
chmod 16
utime 17
time 18
Compiler Switches
=================
The following d30v specific compiler switches are currently supported:
-mextmem Link .text/.data/.bss/etc in external memory.
-mextmemory Same as -mextmem.
-monchip Link .text/.data/.bss/etc in the onchip data/text
memory.
-mno-asm-optimize Do not pass -O to the assembler when optimizing (the -O
switch will mark two short instructions that don't
interfere with each other as being done parallel
instead of sequentially).
-masm-optimize [default] If optimizing, pass -O to the assembler.
-mbranch-cost=n Increase the internal costs of branches to n. Higher
costs means that the compiler will issue more
instructions to avoid doing a branch. The default is
2.
-mcond-exec=n Replace branches around n insns with conditional
execution if we can. Default is 4.
Sections
========
You can override the effect of the -mextmem/-monchip options by putting
functions into either the ".stext" or ".etext" sections. If you put them into
the ".stext" section, the linker will always link the function into the onchip
memory area. Similarly, if you put the function in the ".etext" section, the
linker will always link the function into the external memory area.
Data can be controlled as well. If you put the data in the ".sdata" section,
the linker will put the data into the onchip data area. Similarly, if you put
the data in the ".edata" section, the linker will put the data into the
external memory.
Stack pointer
=============
The crt0.o that we ship loads up the stack pointer with the value of the label
__stack. If you do not define a value for __stack, the linker will choose the
top of the onchip data area (0x20008000) for the stack pointer. You can set a
new value via the options:
-Wl,-defsym,__stack=0x20008000
