Commit Message

Joseph Myers April 8, 2024, 9:19 p.m. UTC 
C23 adds various <math.h> function families originally defined in TS
18661-4.  Add the log2p1 functions (log2(1+x): like log1p, but for
base-2 logarithms).

This illustrates the intended structure of implementations of all
these function families: define them initially with a type-generic
template implementation.  If someone wishes to add type-specific
implementations, it is likely such implementations can be both faster
and more accurate than the type-generic one and can then override it
for types for which they are implemented (adding benchmarks would be
desirable in such cases to demonstrate that a new implementation is
indeed faster).

The test inputs are copied from those for log1p.  Note that these
changes make gen-auto-libm-tests depend on MPFR 4.2 (or later).

The bulk of the changes are fairly generic for any such new function.
(sysdeps/powerpc/nofpu/Makefile only needs changing for those
type-generic templates that use fabs.)

Tested for x86_64 and x86, and with build-many-glibcs.py.

---

This is explicitly proposed for review (in particular, the overall
intended structure of all such patches for these functions should be
reviewed), not for applying without review as math maintainer.

Dear Joseph,

I tried your patch on a x86_64, it applies cleanly, everything compiles
cleanly, and I can use the new log2p1 function in both binary32, binary64,
double-extended and binary128.

As for accuracy, here are the largest errors I found for rounding to nearest:

float 0x1.a69b4ap-2 1.88 ulps
double 0x1.a7b725780ff2cp-2 1.87575 ulps
long double 0x5.dda3a1f4c4020ebp-4l 4.04684 ulps
Float128 -0x7.fff3a57fdd2666bcecba33bd89f4p-4 3.34125 ulps

Probably some values in libm-test-ulps should be updated.

Best regards,
Paul

In general I encourage adding extra tests to auto-libm-test-in where they 
show errors, for any implementation in glibc, larger than those inputs 
already present (but not so large that they cannot be entered in 
libm-test-ulps files).  So adding such inputs for log2p1 would be 
appropriate after this patch is in, and the same applies for all the other 
C23 functions as they get added.

Hi Joseph,

I would prefer that you submit a v2 including the inputs yielding larger
errors that I pointed out in my review.

Paul

I think that's out of scope for this patch in the same way that adding 
benchmarks, or optimized function implementations for particular formats, 
or for that matter updating all the architecture-specific libm-test-ulps 
files, is out of scope: the design for this patch, and thus for all the 
subsequent patches adding such APIs (TS 18661-4 interfaces adopted in 
C23), is to provide the API and ABI in glibc with everything required for 
such a new interface (including being sufficiently accurate that errors 
are within the bounds accepted in libm-test-ulps files, and having tests 
of a representative range of inputs), but going for simplicity of 
implementation rather than trying to cover things that can reasonably be 
done in subsequent incremental improvements after the API and ABI have 
been added.

This fails CI for glibc:

Please review the results and work with Linaro to ensure this passes.

New ulps failures are expected for new libm functions.  I think it's 
appropriate for libm-test-ulps updates to be done by architecture 
maintainers or others testing on an architecture (not necessarily for 
every patch, sometimes such testers might batch updates and update 
libm-test-ulps for multiple architectures at a time), rather than 
expecting them all to be included in the initial patch or making such 
functions need a multi-stage patch process where the initial patch needs 
updating with more libm-test-ulps updates before commit.

(There is a reasonable argument for having a single libm-test-ulps file 
that lists expected error bounds by format (e.g. binary64, binary128) not 
type, notwithstanding that sometimes multiple implementations are used for 
a given function for a given floating-point format, and notwithstanding 
that sometimes the ulps for a given implementation may depend on e.g. 
whether the compiler contracts operations when building it.  But while we 
have the per-architecture files, I don't think we should expect 
new-function patches to update them for more than one architecture.)
Joseph Myers April 29, 2024, 1:34 p.m. UTC | #8 
I'd like to ping this patch 
<https://sourceware.org/pipermail/libc-alpha/2024-April/155960.html>, and, 
in particular:

(a) the actual content of the patch, which no-one has commented on 
(instead preferring to suggest other things to add to it);

(b) the questions of what goes in such patches, where I argue that we 
should not expect libm-test-ulps updates for more than one architecture, 
or additional test inputs based on searches for worst-case inputs, to be 
included in such a patch: that it should be sufficient to include 
libm-test-ulps updates for a single architecture, and tests that seem 
appropriate based on the mathematical properties of the function being 
tested, and further additions there can reasonably be made in followup 
patches.  (Note that even if we moved to a single libm-test-ulps shared 
between architectures and listing expected ulps based on floating-point 
format rather than type, it still wouldn't be possible to update all ulps 
on a single system: no architecture supports both ldbl-96 and 
ldbl-128ibm.)

Dear Joseph,

I have already given my opinion on this patch (after sending several hours
to exercise it):

https://sourceware.org/pipermail/libc-alpha/2024-April/156007.html

I now let other people comment.
