From: Vladimir Mezentsev <vladimir.mezentsev@oracle.com>
Tested on aarch64-linux-gnu, x86_64-pc-linux-gnu and sparc64-unknown-linux-gnu.
No regression. New tests now passed.
There is a performance degradation for complex double type:
failed cases | time
old new | old new
complex-32 15 0 | 3.51 3.56
complex-64 19 0 | 1.88 2.34
complex-128 34 0 | 3.71 2.88

This is, of course, something to consider for GCC 9; it's not suitable for
the current development stage.
Could you provide a more extended writeup of the issue (starting with the
argument for it being a bug at all), the approach you took and the
rationale for the approach, when you resubmit the patch for GCC 9 stage 1?
> * libgcc/config/sparc/sfp-machine.h: New
Are you introducing a requirement for all architectures to provide
sfp-machine.h? If so, did you determine that SPARC was the only one
lacking it? If not the only one lacking it, you need to make sure that
you do not break any existing architecture in GCC.
What about architectures using non-IEEE formats? soft-fp is not suitable
for those, but you mustn't break them. Remember that e.g. TFmode can be
IBM long double, and other ?Fmode similarly need not be IEEE; the name
only indicates how many bytes are in the format, nothing else about it.
What about powerpc __divkc3?
What was the rationale for using soft-fp rather than adding appropriate
built-in functions as suggested in a comment?
These are the sorts of issues you need to cover in your patch write-up, to
demonstrate that you have allowed for the range of targets supported in
GCC, have taken care to avoid breaking them and have made deliberate
choices that are appropriate in each case (but might not be the same for
every target).
> +static inline int get_cde(int c, int d)
Lots of the new functions need comments on them to explain their
semantics. Also, the formatting needs fixing to follow the GNU Coding
Standards ("static inline int" on its own line, space before '(').
> + if (cde != 0) {
Similarly, bad formatting, "{" goes on the next line.

The formula for complex division (a+bi)/(c+di) is (a*c+b*d)/(c*c+d*d) +
(b*c-a*d)/(c*c+d*d)i
The current implementation avoids overflow in (c*c + d*d) using
x=MAX(|c|, |d|);Â c1=c/x; d1=d/x;
and then calculating the result as
(a*c1+b*d1)/(c1*c1+d1*d1)*(1.0/x) + (b*c1-a*d1)/(c1*c1+d1*d1)*(1.0/x)i
This approach has two issues:
1. Unexpected rounding when x is not a power of 2.0
For example, (1.0+3.0i) /(1.0+3.0i) should be 1.0
but it is (1.0 - 1.66533e-17i) on aarch64 (PR59714)
2. Unexpected underflow in c/x or d/x.
For example, (0x1.0p+1023 + 0x0.8p-1022 i)/(0x1.0p+677 + 0x1.0p-677 i)
should be (0x1.0p+346 - 0x1.0p-1008 i) but it is (0x1.0p+346)
My implementation avoids these issues.

Agree.Â
An additional fix is needed.
Build can be broken without sfp-mashine.h or on architectures using
non-IEEE format.

I had a version with built-in functions and I can restore it.
Let's design what we want to use soft-fp or built-in function.
I'd prefer to use built-in functions but performance is in two times worse.
The test below demonstrates performance degradation:
% cat r1.c
#include <stdio.h>
int main(int argc, char** argv)
{
 int i;
 long long sum = 0;
 for(i = 1; i < 1000000000; i++)
   {
     int exp;
     double d = (double) i;
#ifdef BUITIN
     double v = __builtin_frexp(d, &exp);
#else
     union _FP_UNION_D
     {
       double flt;
       struct _FP_STRUCT_LAYOUT
       {
         unsigned frac0 : 32;
         unsigned frac1 : 20;
         unsigned exp  : 11;
         unsigned sign : 1;
       } bits __attribute__ ((packed));
       long long LL;
     } u;
     u.flt = d;
     exp = u.bits.exp - 1022;
#endif
     sum += exp * (i % 2 == 0 ? 1 : -1);
   }
 printf("sum = %d\n", sum);
 return 0;
}

So, this is comparing __builtin_frexp (extracting both exponent and
mantissa, including appropriate handling of exponents of subnormal values)
with just extracting the exponent and with no special handling of zero /
infinity / NaN / subnormal values.
We need to consider what functionality is actually needed for this
scaling, if we do wish to use such scaling based on integer exponents. If
what's needed corresponds exactly to some standard functions such as ilogb
and scalbn with all their special cases, then built-in versions of those
standard functions may make sense. If what's needed does not correspond
to standard functions and does not need to handle such special cases,
that's more of an indication for examining the representation in libgcc -
but it's still necessary to handle the many different variant
floating-point formats supported, or to safely avoid using the new code
for formats it can't handle.

 I compared with __builtin_ilogb. There is a same performance degradation.

 The IEEE format for double is  <sign : 1> <exponent : 11> <fraction :
52>.
We need a function like extract_exponent_field.
 All standard function make an additional work to get exponent.
It is a reason why we see performance degradation.
% cat r2.c
#include <stdio.h>
int main(int argc, char** argv)
{
 double d = 0x0.004p-1023;
 printf("d=%-24.13a exp=%d\n", d, __builtin_ilogb(d));
 return 0;
}
% gcc -O2 -lm r2.c ; ./a.out
d=0x0.0020000000000p-1022Â Â *exp=-1033

I'm not clear on exactly what you compared with.
Do you mean the *existing* __builtin_ilogb? That's only supported for
constant arguments that are not zero, infinity or NaN, and with an i386
optab for -funsafe-math-optimizations. So it's not a useful comparison at
all, because it would call a libm function.
Rather, if built-in functions were used for this, they'd be *new* built-in
functions. It would be entirely possible to implement __builtin_ilogb (at
least for -fno-math-errno) that actually expands inline, using target
hooks to provide the values of FP_ILOGB0 / FP_ILOGBNAN, though the
expansion might be too big to be generally useful.
But a built-in function specifically to extract the exponent field of a
floating-point number (without doing any biasing or adjusting for special
cases) would be a more plausible comparison. The existing description of
floating-point number formats in real.h includes specification of
signbit_ro and signbit_rw. It would be possible to have such a
specification of the location of an exponent field, where there's one that
can be located simply within the floating-point number, and then
machine-independent code to expand such a built-in function.
I'm not asserting that you should add such a function. I *am* asserting
that the patch proposal needs to include serious consideration of various
options such as:
* Adding such a built-in function.
* Adding predefined macros (conditional on -fbuilding-libgcc) that assert
that a particular floating-point mode has a particular IEEE format.
Such predefined macros have a clear precedent - we already have
__LIBGCC_%s_MANT_DIG__, __LIBGCC_HAS_%s_MODE__, __LIBGCC_%s_FUNC_EXT__,
__LIBGCC_%s_EXCESS_PRECISION__. So why not something to describe IEEE
properties of a machine mode?
The use of sfp-machine.h is problematic because, while having
sfp-machine.h implies use of at least some IEEE formats, there is no
implication the other way round: sfp-machine.h is only present if at least
one format uses software floating point, not if all use hardware floating
point (or use software floating point in libc not libgcc, or use software
floating point from fp-bit instead of soft-fp). That's not a particularly
sensible criterion for whether to use the new logic.
Furthermore, it's entirely possible that only some formats are IEEE -
thus, on powerpc64le, __LIBGCC_HAS_TF_MODE__ is true, and soft-fp.h is
present, but TFmode is actually IBM long double not IEEE binary128, so
your logic would handle that case incorrectly. Thus you need "mode X has
IEEE format Y" logic that avoids the case where mode X exists, and IEEE
format Y is supported, and sfp-machine.h exists, but mode X has another
format, because that's actually the case right now for TFmode on
powerpc64le.
Again, I'm not saying you should add such predefined macros - but at a
first look I think they are a better approach than the use of presence of
sfp-machine.h to indicate which modes have IEEE formats, and I think they
are among the options that any patch submission needs to discuss carefully
if rejecting.

If you're seeing it used as a struct tag, that means you're missing an
inclusion of soft-fp.h which is required to be able to include the other
soft-fp headers. But really I suspect that using soft-fp headers is a
mistake here, because of the dependence on per-machine sfp-machine.h that
should generally be irrelevant for your purposes (beyond having some way
to declare appropriate struct layouts).

We see 'struct _FP_STRUCT_LAYOUT' is declared twice (in lines 206 and
210) inside union _FP_UNION_Q.

I think you still need to provide a more detailed explanation of the
implementation approach (discussing the issues and choices made, how and
why it's safe on all systems, how your code avoids any problems with
subnormals, infinities and NaNs, etc.).
As far as I can tell, the argument for better performance compared to
built-in functions is that a generally useful built-in function would need
special handling of infinities, NaNs, zero and subnormals, which you
avoid by e.g. extracting exponent fields directly. This means that a
detailed justification is needed of how it's safe for the exponent fields
of such values to be passed straight through your various functions
without special cases 0 - probably most of that should go in comments in
the code explaining what happens for such values and why it successfully
avoids overflow and underflow.
The files in libgcc/soft-fp must be verbatim copies of the master sources
in glibc. So you can't make any local changes to them, and if you think
changes are needed you need to patch things upstream in glibc first, with
a proper extended explanation of why the fix is needed and why it is safe
and the appropriate design for the fix. There's nothing at all in this
patch submission to explain that change.
You shouldn't have any commented-out code like your "+//#include
"soft-fp/soft-fp.h"" in the submitted patch.
All the new inline functions need more precise comments explaining what
their semantics are in cases such as zero, subnormals, infinities, etc.,
or stating that the semantics are that such arguments must not be passed
to those functions. (They also need to be formatted according to the GNU
Coding Standards - space before '(', function name starts a new line.)
> +/* Return an exponent N, such that neither (2**(ce-N))**2 nor (2**(de-N))**2
> + cause an overflow. Also try to avoid underflow. */
So (for example), for this comment, I'd expect information about: what is
the valid range of exponents N that this function may return (given that,
I suppose, you want 2**N to be a representable floating-point value), and
what are the valid ranges of CE and DE for which this function guarantees
to achieve those semantics with an exponent within the required range?
And are those semantics strictly for the actual numbers specified, or,
given how a subnormal value may result in an exponent -EXPBIAS here
despite the actual exponent being smaller, are there additional semantics
required in the case where CE or DE is -EXPBIAS?
Once there are comments on these functions giving all the required
semantics, we can start to reason about whether those semantics ensure the
required higher-level properties (regarding overflow / underflow in
__div*c3 functions) in the case where subnormals are involved. I'd expect
such reasoning to appear in comments in the code.

Tested on aarch64-linux-gnu, x86_64-pc-linux-gnu and sparc64-unknown-linux-gnu.
No regression. New tests now passed.
There is a performance degradation for complex double type:
failed cases | time
old new | old new
complex-32 15 0 | 3.51 3.56
complex-64 19 0 | 1.88 2.34
complex-128 34 0 | 3.71 2.88
The formula for complex division (a+bi)/(c+di) is (a*c+b*d)/(c*c+d*d) + (b*c-a*d)/(c*c+d*d)i
The current implementation avoids overflow in (c*c + d*d) using
x=MAX(|c|, |d|); c1=c/x; d1=d/x;
and then calculating the result as
(a*c1+b*d1)/(c1*c1+d1*d1)*(1.0/x) + (b*c1-a*d1)/(c1*c1+d1*d1)*(1.0/x)i
This approach has two issues:
1. Unexpected rounding when x is not a power of 2.0
For example, (1.0+3.0i) /(1.0+3.0i) should be 1.0
but it is (1.0 - 1.66533e-17i) on aarch64 (PR59714)
2. Unexpected underflow in c/x or d/x.
For example, (0x1.0p+1023 + 0x0.8p-1022 i)/(0x1.0p+677 + 0x1.0p-677 i)
should be (0x1.0p+346 - 0x1.0p-1008 i) but it is (0x1.0p+346)
My implementation avoids these issues.
I use soft-fp instead built-in functions because performance with built-in
functions (like __builtin_ilogb) is in two times worse.
Also libm is needed for built-in functions.
Restrictions:
An old implementation is used when an architecture doesn't provide sfp-machine.h
An old implementation is used for __divkc3 (I have no access on rs6000 for testing)

I am unconvinced of the need for a change that reduces accuracy in some
cases to make things less surprising in other cases.
I am clear that if there is to be such a change, it should be made
consistently for all affected floating-point modes, including TFmode /
KFmode where available, since those have fused operations on some
platforms.

  Hello Joseph and GCC-team,
Different people are giving me different directions.
I am glad to change my fix but please provide clear directions on how
you want to see it.
 michael.hudson@linaro.org created PR 59714 and suggested to setÂ

FMA (floating-point multiply-add) instructions are supported on aarch64.
These instructions can produce different result if two operations executed separately.
-ffp-contract=off doesn't allow the FMA instructions.
Tested on aarch64-unknown-linux-gnu. No regression. Two failed tests now passed.

Without regard to whether the change is appropriate in the first place,
I'm doubtful of the logic for selecting floating-point modes. I'd expect
something that applies to all floating-point modes. Even if nothing has
fused XFmode operations, some architectures (e.g. s390, powerpc) have
fused operations on TFmode / KFmode.

In original (without my fix) libgcc_s.so:

In my new libgcc_s.so ( see my fix below)

Only 3 (_divdc3 / _divhc3 / _divsc3) have FMAs.
The other FMAs are in:
_fixunsdfdi.o _fixunsdfdi_s.o _fixunssfdi.o _fixunssfdi_s.o _muldc3.o
_muldc3_s.o _mulhc3.o _mulhc3_s.o _mulsc3.o _mulsc3_s.o
I suggest the following fix:

Eg. objdump -d ~/install/gcc/lib64/libgcc_s.so | grep -c fmadd
Also grep fmsub, fnmadd, fnmsub.

I don't think this will work in general, IIRC only a few targets correctly
implement the optimize pragma. Changing the makefile to build only
__divdc3/__divtc3/__divsc3/__divhc3 without FMA looks like a better
approach.
However we also need to decide whether this is the best possible fix.
It will affect accuracy of other inputs as well...

How can I find this number ?
dis <all functions in libgcc> | grep <all FMAs> | wc
Or are there the other simple ways ?

It's probably better to do this with an attribute
__attribute__((optimize("fp-contract=off")))
on the affected functions.

It looks like this disables fp-contract in all of libgcc...
What is the the number of FMAs in libgcc before/after?
If it disables anything other than the ones in complex division, it
would have an unintended performance impact. It's best to do
this just for complex division.

FMA (floating-point multiply-add) instructions are supported on aarch64.
These instructions can produce different result if two operations executed separately.
-ffp-contract=off doesn't allow the FMA instructions.
Tested on two platforms:
aarch64-unknown-linux-gnu: No regression. Two failed tests now passed.
sparc64-unknown-linux-gnu: No regression.
ChangeLog:
