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 |
|

|
||||
|
||||
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

This directory contains code for building a compiler for the
|
||||
32-bit ESA/390 architecture. It supports three different styles
|
||||
of assembly:
|
||||
|
||||
-- MVS for use with the HLASM assembler
|
||||
-- Open Edition (USS Unix System Services)
|
||||
-- ELF/Linux for use with the binutils/gas GNU assembler.
|
||||
|
||||
|
||||
Cross-compiling Hints
|
||||
---------------------
|
||||
When building a cross-compiler on AIX, set the environment variable CC
|
||||
and be sure to set the -ma and -qcpluscmt flags; i.e.
|
||||
|
||||
export CC="cc -ma -qcpluscmt"
|
||||
|
||||
do this *before* running configure, e.g.
|
||||
|
||||
configure --target=i370-ibm-linux --prefix=/where/to/install/usr
|
||||
|
||||
The Objective-C and FORTRAN front ends don't build. To avoid looking at
|
||||
errors, do only
|
||||
|
||||
make LANGUAGES=c
|
||||
|
||||
|
||||
OpenEdition Hints
|
||||
-----------------
|
||||
The shell script "install" is handy for users of OpenEdition.
|
||||
|
||||
|
||||
The ELF ABI
|
||||
-----------
|
||||
This compiler, in conjunction with the gas/binutils assembler, defines
|
||||
a defacto ELF-based ABI for the ESA/390 architecture. Be warned: this
|
||||
ABI has several major faults. It should be fixed. As it is fixed,
|
||||
it is subject to change without warning. You should not commit to major
|
||||
software systems without further exploring and fixing these problems.
|
||||
Here are some of the problems:
|
||||
|
||||
-- No support for shared libraries or dynamically loadable objects.
|
||||
This is because the compiler currently places address literals in
|
||||
the text section. Although the GAS assembler supports a syntax for
|
||||
USING that will place address literals in the data section, this forces
|
||||
the use of two base registers, one for branches and one for the literal
|
||||
pool. Work is needed to redesign the function prologue, epilogue and the
|
||||
base register reloads to minimize the currently excessive use of reserved
|
||||
registers.
|
||||
|
||||
I beleive the best solution would be to add a toc or plt, and extending
|
||||
the meaning of the USING directive to encompass this. This would
|
||||
allow the continued use of the human-readable and familiar practice
|
||||
of using =A() and =F'' to denote address literals, as opposed to more
|
||||
difficult jump-table notation.
|
||||
|
||||
-- the stackframe is almost twice as big as it needs to be.
|
||||
|
||||
-- currently, r15 is used to return 32-bit values. Because this is the
|
||||
last register, it prevents 64-bit ints and small structures from being
|
||||
returned in registers, forcing return in memory. It would be more
|
||||
efficient to use r14 to return 32-bit values, and r14+r15 to return
|
||||
64-bit values.
|
||||
|
||||
-- all arguments are currently passed in memory. It would be more efficient
|
||||
to pass arguments in registers.
|
||||
|
||||
|
||||
|
||||
|
||||
ChangeLog
|
||||
---------
|
||||
Oct98-Dec98 -- add ELF back end; work on getting ABI more or less functional.
|
||||
98.12.05 -- fix numerous MVC bugs
|
||||
99.02.06 -- multiply insn sometimes not generated when needed.
|
||||
-- extendsidi bugs, bad literal values printed
|
||||
-- remove broken adddi subdi patterns
|
||||
99.02.15 -- add clrstrsi pattern
|
||||
-- fix -O2 divide bug
|
||||
99.03.04 -- base & index reg usage bugs

|
||||
99.03.29 -- fix handling & alignment of shorts
|
||||
99.03.31 -- clobbered register 14 is not always clobbered
|
||||
99.04.02 -- operand constraints for cmphi
|
||||

||||
99.04.28 -- reg 2 is clobbered by calls
|
||||
99.04.30 -- fix rare mulsi bug
|
||||
99.04.30 -- add constraints so that all RS, SI, SS forms insns have valid
|
||||
addressing modes
|
||||
99.04.30 -- major condition code fixes. The old code was just way off
|
||||
w.r.t. which insns set condition code, and the codes that
|
||||
were set. The extent of this damage was unbeleivable.
|
||||
99.05.01 -- restructuring of operand constraints on many patterns,
|
||||
many lead to invalid instructions being genned.
|
||||
99.05.02 -- float pt fixes
|
||||
-- fix movdi issue bugs
|
||||
99.05.03 -- fix divide insn; was dividing incorrectly
|
||||
99.05.05 -- fix sign extension problems on andhi
|
||||
-- deprecate some constraints
|
||||
99.05.06 -- add set_attr insn lengths; fix misc litpool sizes
|
||||
-- add notes about how unsigned jumps work (i.e.
|
||||
arithmetic vs. logical vs. signed vs unsigned).
|
||||
99.05.11 -- use insn length to predict forward branch target;
|
||||
use relative branchining where possible,
|
||||
remove un-needed base register reload.
|
||||
99.05.15 -- fix movstrsi, clrstrsi, cmpstrsi patterns as per conversation

These @samp{-m} options are defined for the Intel 960 implementations:

@table @gcctabopt
|
||||
@item -m@var{cpu-type}
|

|
||||
Assume the defaults for the machine type @var{cpu-type} for some of
|
||||
the other options, including instruction scheduling, floating point
|
||||
support, and addressing modes. The choices for @var{cpu-type} are
|
||||
@samp{ka}, @samp{kb}, @samp{mc}, @samp{ca}, @samp{cf},
|
||||
@samp{sa}, and @samp{sb}.
|
||||
The default is
|
||||
@samp{kb}.
|
||||
|
||||
@item -mnumerics
|
||||
@itemx -msoft-float
|
||||
@opindex mnumerics
|
||||
@opindex msoft-float
|
||||
The @option{-mnumerics} option indicates that the processor does support
|
||||
floating-point instructions. The @option{-msoft-float} option indicates
|
||||
that floating-point support should not be assumed.
|
||||
|
||||
@item -mleaf-procedures
|
||||
@itemx -mno-leaf-procedures
|
||||
@opindex mleaf-procedures
|
||||
@opindex mno-leaf-procedures
|
||||
Do (or do not) attempt to alter leaf procedures to be callable with the
|
||||
@code{bal} instruction as well as @code{call}. This will result in more
|
||||
efficient code for explicit calls when the @code{bal} instruction can be
|
||||
substituted by the assembler or linker, but less efficient code in other
|
||||
cases, such as calls via function pointers, or using a linker that doesn't
|
||||
support this optimization.
|
||||
|
||||
@item -mtail-call
|
||||
@itemx -mno-tail-call
|
||||
@opindex mtail-call
|
||||
@opindex mno-tail-call
|
||||
Do (or do not) make additional attempts (beyond those of the
|
||||
machine-independent portions of the compiler) to optimize tail-recursive
|
||||
calls into branches. You may not want to do this because the detection of
|
||||
cases where this is not valid is not totally complete. The default is
|
||||
@option{-mno-tail-call}.
|
||||
|
||||
@item -mcomplex-addr
|
||||
@itemx -mno-complex-addr
|
||||
@opindex mcomplex-addr
|
||||
@opindex mno-complex-addr
|
||||
Assume (or do not assume) that the use of a complex addressing mode is a
|
||||
win on this implementation of the i960. Complex addressing modes may not
|
||||
be worthwhile on the K-series, but they definitely are on the C-series.
|
||||
The default is currently @option{-mcomplex-addr} for all processors except
|
||||
the CB and CC@.
|
||||
|
||||
@item -mcode-align
|
||||
@itemx -mno-code-align
|
||||
@opindex mcode-align
|
||||
@opindex mno-code-align
|
||||
Align code to 8-byte boundaries for faster fetching (or don't bother).
|
||||
Currently turned on by default for C-series implementations only.
|
||||
|
||||
@ignore
|
||||
@item -mclean-linkage
|
||||
@itemx -mno-clean-linkage
|
||||
@opindex mclean-linkage
|
||||
@opindex mno-clean-linkage
|
||||

@itemx -mic3.0-compat
|
||||
@opindex mic-compat
|
||||
@opindex mic2.0-compat
|
||||
@opindex mic3.0-compat
|
||||
Enable compatibility with iC960 v2.0 or v3.0.
|
||||
|
||||
@item -masm-compat
|
||||
@itemx -mintel-asm
|
||||
@opindex masm-compat
|
||||
@opindex mintel-asm
|
||||
Enable compatibility with the iC960 assembler.
|

|
||||
@item -mstrict-align
|
||||
@itemx -mno-strict-align
|
||||
@opindex mstrict-align
|
||||
@opindex mno-strict-align
|
||||
Do not permit (do permit) unaligned accesses.
|
||||
|
||||
@item -mold-align
|
||||
@opindex mold-align
|
||||
Enable structure-alignment compatibility with Intel's gcc release version
|
||||
1.3 (based on gcc 1.37). This option implies @option{-mstrict-align}.
|
||||
|
||||
@item -mlong-double-64
|
||||
@opindex mlong-double-64
|
||||
Implement type @samp{long double} as 64-bit floating point numbers.
|
||||
Without the option @samp{long double} is implemented by 80-bit
|
||||
floating point numbers. The only reason we have it because there is
|
||||
no 128-bit @samp{long double} support in @samp{fp-bit.c} yet. So it
|
||||
is only useful for people using soft-float targets. Otherwise, we
|
||||
should recommend against use of it.

adjacent short instructions where possible.
|

@item -mbranch-cost=@var{n}

@opindex mbranch-cost
|

Increase the internal costs of branches to @var{n}. Higher costs means

that the compiler will issue more instructions to avoid doing a branch.

The default is 2.
|

@item -mcond-exec=@var{n}
