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:

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

gcc/config/i370/README deleted 100644 → 0
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
99.03.15 -- fixes for returning long longs and structs (struct value return)
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
99.04.07 -- function pointer fixes for call, call_value patterns,
function pointers derefed once too often.
99.04.14 -- add pattern to print double-wide int
-- check intval<4096 for misc operands
-- add clrstrsi pattern
-- movstrsi fixes
99.04.16 -- use r2 to pass args into r11 in subroutine call.
-- fixes to movsi; some operand combinations impossible;
rework constraints
-- start work on forward jump optimization
-- char alignment bug
99.04.25 -- add untyped_call pattern so that builtin_apply works
99.04.27 -- fixes to compare logical under mask
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}
@opindex mka
@opindex mkb
@opindex mmc
@opindex mca
@opindex mcf
@opindex msa
@opindex msb
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

@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.

@opindex mno-asm-optimize
@opindex masm-optimize
Disable (enable) passing @option{-O} to the assembler when optimizing.
The assembler uses the @option{-O} option to automatically parallelize
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.
