The generic implementation is slight worse (Itanium(R) Processor 9020):
Before new code:
"exp10f": {
"workload-spec2017.wrf (adapted)": {
"duration": 3.61582e+08,
"iterations": 2.384e+07,
"reciprocal-throughput": 14.8334,
"latency": 15.5006,
"max-throughput": 6.74153e+07,
"min-throughput": 6.45136e+07
}
}
With new code:
"exp10f": {
"workload-spec2017.wrf (adapted)": {
"duration": 3.85549e+08,
"iterations": 2.384e+07,
"reciprocal-throughput": 15.8391,
"latency": 16.5056,
"max-throughput": 6.31348e+07,
"min-throughput": 6.05857e+07
}
}
However it fixes all the issues on both:
math/test-float-exp10
math/test-float32-exp10
(all the issues wrong results for non default rounding modes).
The existing ia64 libm interface uses matherrf and matherrl in addition
to matherr for SVID error handling. However, there is no such error
handling support for exp10f in ia64 libm. So replacing it with the
generic implementation should be fine.
Checked on ia64-linux-gnu.
With mathinline removal there is no need to keep building and testing
inline math tests.
The gen-libm-tests.py support to generate ULP_I_* is removed and all
libm-test-ulps files are updated to longer have the
i{float,double,ldouble} entries. The support for no-test-inline is
also removed from both gen-auto-libm-tests and the
auto-libm-test-out-* were regenerated.
Checked on x86_64-linux-gnu and i686-linux-gnu.
I noticed that some libm-test-ulps files still had long-obsolete
entries for *_tonearest functions, which will no longer be used since
functions with FE_TONEAREST explicitly set aren't tested separately
from those functions with it as the default rounding mode any more.
This patch removes those obsolete entries. However, as they are a
sign of libm-test-ulps not having been regenerated from scratch for a
long time, I strongly advise people testing on those platforms to
remove / truncate the libm-test-ulps file, run "make regen-ulps" and
commit the regenerated-from-scratch file. (Ideally any failures of
libm tests still present after regeneration would be investigated /
fixed - there are several open "math" bugs spread across these
platforms - but simply regenerating from scratch improves things.)

As recently discussed
<https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it
doesn't seem particularly useful for libm-test-ulps files to contain
huge amounts of data on ulps for individual tests; just the global
maximum observed ulps for each function, together with the
verification of exceptions, errno and special results such as
infinities and NaNs for each test, suffices to verify that a
function's behavior on the given test inputs is within the expected
accuracy. Removing this data reduces source tree churn caused by
updates to these files when libm tests are added, and reduces the
frequency with which testsuite additions actually need libm-test-ulps
changes at all.
Accordingly, this patch removes that data, so that individual tests
get checked against the global bounds for the given function and only
generate an error if those are exceeded. Tested x86_64 (including
verifying that if an ulps value is artificially reduced, the tests do
indeed fail as they should and "make regen-ulps" generates the
expected changes).
