Hello,
I would like to configure a bi-arch PowerPC GCC. My naive approach was
simply:

This is stack_restore_tie, which requires TARGET_32BIT.
It currently is only generated from rs6000_emit_stack_reset:
/* This blockage is needed so that sched doesn't decide to move
the sp change before the register restores. */
if (DEFAULT_ABI == ABI_V4
|| (TARGET_SPE_ABI
&& info->spe_64bit_regs_used != 0
&& info->first_gp_reg_save != 32))
return emit_insn (gen_stack_restore_tie (updt_reg_rtx, frame_reg_rtx,
GEN_INT (frame_off)));
so you seem to have 64-bit ABI_V4? I wonder how well tested that is,
you are likely to run into more problems. Either stack_restore_tie or
the above code will need a tweak.

thanks for your help. I would had a hard time to figure this out myself.
I am flexible in terms of the ABI choice for the 64-bit PowerPC. I guess
the ABI_ELFv2 is the way to go?
I had to provide SUBSUBTARGET_OVERRIDE_OPTIONS in rtems.h (in
config/rs6000/) to set the ABI. The sysv4.h doesn't care about
-mabi=elfv2. There seems to be some copy and paste in linux64.h and
freebsd64.h for their SUBSUBTARGET_OVERRIDE_OPTIONS. Maybe the common
stuff should move to sysv4.h?

It certainly is the most modern ABI. It makes some requirements to what
Power ISA features are required, which may or may not be a problem for
your platform. If you want to use BE, that should work with ELFv2 fine
(and it did in the past at least), but it doesn't get serious testing.

sysv4 is not ELFv2, it is a separate ABI. Perhaps there should be an
elfv2.h header, sure.

From rs6000.c (rs6000_scalar_mode_supported_p):
else if (TARGET_FLOAT128_TYPE && (mode == KFmode || mode == IFmode))
return true;
else
return default_scalar_mode_supported_p (mode);
and the latter has
if (precision == LONG_DOUBLE_TYPE_SIZE)
return true;
return false;
so you have no 128-bit FP type at all. Maybe your TARGET_IEEEQUAD definition
is wrong, maybe something else... What type *do* you want for float128?

rs6000_legitimize_address called force_reg which ICEs in emit_move_insn
because the source is not the same mode as the dest (or an immediate, etc.)
You'll have to debug this a bit more to see what is going on.

You might want to break this line into parts. It isn't so easy to see what
you changed now :-)
Have you checked if your generated files (say, those in libgcc) are
actually ELFv2 now, and if they look correct?

I disabled the ibm-ldouble.c for RTEMS. Enabling the 128-bit FP support
for the 32-bit powerpc-rtems resulted in a lot of ICEs.
https://gcc.gnu.org/ml/gcc/2017-01/msg00215.html
With -m64 I set now:
+ if (rs6000_isa_flags & OPTION_MASK_64BIT) \
+ { \
+ rs6000_long_double_type_size = 128; \
+ rs6000_elf_abi = 2; \
+ rs6000_current_abi = ABI_ELFv2; \
+ rs6000_isa_flags &= ~OPTION_MASK_EABI; \

I still get a lot of ICEs with the attached two patches (examples):
/home/EB/sebastian_h/archive/gcc-git/libgcc/libgcc2.c: In function
'__multc3':

I compared the linux64.h and freebsd64.h and as a wild guess I added:
+#undef TARGET_AIX
+#define TARGET_AIX TARGET_64BIT
+
This seems to fix this issue. I don't know why.

I simply added rs6000/biarch64.h to the head of the list.

The IEEE128 code almost certainly has some bugs on non-Linux configurations.
You could try debugging it, or you could avoid it (for now) by e.g. making
long double the same as double.

This sounds like your uintptr_t is a 32-bit type? That won't work.

If I set rs6000_long_double_type_size to 64, then I can build all libgcc
multilibs including the one for -m64 -mcpu=e6500. I am a bit surprised
that the GCC support for 64-bit PowerPC is so extremely Linux-dependent.
I guess that I have to figure out all the magic configuration bits to
get everything set up like it is on Linux. It would be nice if the
working Linux configuration bits are the default.
With rs6000_long_double_type_size == 128, then I get the attached ICEs.
I would be glad to get some advice how I can debug them, since I have no
idea how the compiler works actually if it comes to code generation.

These are normal. Maybe it would work (and not warn) if we left off
the constraints as well, hrm.

This is an SPE pattern, won't be a problem for you. It should probably
be CCmode fwiw.

Good, so you have a way forward now. You probably do not want to keep
this forever, of course ;-)

It is not. It also supports FreeBSD (which of course is very much like
Linux), and AIX and Darwin.
But the focus is on Linux, sure.

There are hundreds of knobs you can turn. Not all combinations make
sense. Not all the non-sensical combinations are handled gracefully.

The IEEE128 code is quite new, and of course still has bugs. You do
not want to use "double-double" in a new ABI though.

This is probably created via:
(define_expand "cbranch<mode>4"
[(use (match_operator 0 "rs6000_cbranch_operator"
[(match_operand:FP 1 "gpc_reg_operand" "")
(match_operand:FP 2 "gpc_reg_operand" "")]))
(use (match_operand 3 ""))]
""
"
{
rs6000_emit_cbranch (<MODE>mode, operands);
DONE;
}")
which does
condition_rtx = rs6000_generate_compare (operands[0], mode);
which then does
if (!TARGET_FLOAT128_HW && FLOAT128_VECTOR_P (mode))
comp_mode = CCmode;
else if (FLOAT_MODE_P (mode))
comp_mode = CCFPmode;
else
....
so it seems you have TARGET_FLOAT128_HW set?

But this one has it off. Huh. (The _soft is only generated with it off).

Machine mode is CCFPmode, but what is the RTL code? rs6000_generate_compare
made a mess here.

So it doesn't have a valid FP type here.
All the rest of your errors are duplicates or fallout from earlier
errors.

I gave it a new try after the SPE split up. I still have problems to
build a bi-arch PowerPC compiler for RTEMS. I get an ICE with this test
case:
typedef float TFtype __attribute__ ((mode (TF)));
void
f (TFtype b)
{
if (b - b) {
__asm__ volatile ("");
}
}

So, I looked for " __gcc_qsub" in the GCC sources. It seems this is
generated by rs6000_init_libfuncs() for some "sub_optab" stuff. If I run
my bi-arch GCC in GDB, then I get:
Breakpoint 1, rs6000_init_libfuncs () at
/home/EB/sebastian_h/archive/gcc-git/gcc/config/rs6000/rs6000.c:18670
18670 if (TARGET_FLOAT128_TYPE)
(gdb) n
18677 if (TARGET_LONG_DOUBLE_128)
(gdb)
18684 init_float128_ieee (TFmode);
(gdb) s
init_float128_ieee (mode=TFmode) at
/home/EB/sebastian_h/archive/gcc-git/gcc/config/rs6000/rs6000.c:18581
18581 if (FLOAT128_VECTOR_P (mode))
(gdb) n
18580 {
(gdb)
18581 if (FLOAT128_VECTOR_P (mode))
(gdb)
18640 set_optab_libfunc (add_optab, mode, "_q_add");
(gdb)
18641 set_optab_libfunc (sub_optab, mode, "_q_sub");
Ok, so why do I get a "error: unrecognizable insn:"? How can I debug a
message like this:
(insn 12 11 13 2 (set (reg:CCFP 126)
(compare:CCFP (reg:TF 123)
(reg:TF 124))) "test-v0.i":5 -1
(nil))
I don't know how I can figure out the corresponding GCC sources that are
involved here.

So, this instruction is what was expanded, but it is not a valid
instruction for your configuration.

It ends up in libgcc.a, from ibm-ldouble.c .

In your testcase you use TFmode directly. This either is the
"double-double" ("IBM128") format, or IEEE 128-bit format (another
option for "long double" is to make it the same as "double").
Using a 64-bit long double has as downside that it is not bigger than
double.
Using double-double has as downsides that we are trying to move away
from it, it has funny rounding, historically it has had quite a few
bugs.
IEEE 128-bit is currently only supported on systems with VSX. If you
want to use it on other systems you'll have to make emulation support
for it in libgcc -- which then will work on *all* systems. Maybe
this is a bit much work.

This is supposed to be matched by the cmptf_internal1 pattern with
-mabi=ibmlongdouble. Looks like your configuration defaults to
-mabi=ieeelongdouble.

Yes, originally I tried to enable the 128-bit IEEE float support. I use
now the default settings.
