This patch enables testing of cpow in all rounding modes using
ALL_RM_TEST. There were two reasons this was previously deferred:
* MPC has complicated rounding-mode-dependent rules for the signs of
exact zero real or imaginary parts in the result of mpc_pow. Annex
G does not impose any such requirements and I don't think glibc
should try to implement any particular logic here. This patch adds
support for gen-auto-libm-tests passing the IGNORE_ZERO_INF_SIGN
flag to libm-test.inc.
* Error accumulations in some tests in non-default rounding modes
exceed the maximum error permitted in libm-test.inc. This patch
marks the problem tests with xfail-rounding. (It might be possible
to reduce the accumulations a bit by using round-to-nearest when
cpow calls clog, but I don't think there's much point; the
implementation approach for cpow is fundamentally deficient, as
discussed in the existing bug for cpow inaccuracy which can
reasonably be considered to cover these less-inaccurate cases as
well. It's possible that the test "cpow 2 0 10 0" will also need
xfail-rounding on some platforms.)
Tested x86_64 and x86 and ulps updated accordingly.
* math/gen-auto-libm-tests.c: Document use of
ignore-zero-inf-sign.

This patch fixes the default mode of scalb to set errno (bugs 6803 and
6804).
Previously, the _LIB_VERSION == _SVID_ mode would set errno but only
in some relevant cases, and with various peculiarities (such as errno
setting when an exact infinity or zero result arises with an argument
to scalb being an infinity). This patch leaves this mode
bug-compatible, while making the default mode set errno in accordance
with normal practice (so an exact infinity from an infinite argument
is not an error, and nor is an exact zero result). gen-libm-test.pl
is taught new notation such as ERRNO_PLUS_OFLOW to facilitate writing
the tests of errno setting for underflow / overflow in libm-test.inc.
Note that bug 6803 also covers scalbn and scalbln, but this patch only
addresses the scalb parts of that bug (along with the whole of bug
6804).
Tested x86_64 and x86.

This patch continues improvements to all-rounding-mode libm testing by
making testing with ALL_RM_TEST support test results from
auto-libm-test-out. gen-libm-test.pl is adapted to generate
appropriate output with results for each rounding mode, with
AUTO_TESTS_* calls no longer specifying a rounding mode. Where there
were separate functions in libm-test.inc to test a function in each
rounding mode, using AUTO_TESTS_* to list the tests for each rounding
mode, those are converted to using ALL_RM_TEST (so generally this
patch doesn't change the sets of tests run in each rounding mode,
except that in various cases special-case tests given directly in
libm-test.inc were previously run only for round-to-nearest, and now
are run for all rounding modes).

arguments.
Continuing the move to systematically testing libm functions in all
rounding modes with ALL_RM_TEST, this patch converts the tests of
scalbn and scalbln to use that macro.
Those tests include cases of underflow and overflow, meaning the
expected results depend on the rounding mode. For convenience in
writing such tests manually, the patch adds the notation plus_oflow,
minus_oflow, plus_uflow and minus_uflow for overflowing / underflowing
results of each sign appropriate to the rounding mode being used, and
gen-libm-test.pl is made to substitute in the appropriate values. The
tests of underflow and overflow are extended to include negative
arguments to provide better coverage (otherwise minus_oflow and
minus_uflow wouldn't have been used at all).
(A subsequent patch will make ldexp use the scalbn tests, as those
functions are equivalent for binary floating point.)
Tested x86_64 and x86.
* math/gen-libm-test.pl (parse_args): Handle plus_oflow,
minus_oflow, plus_uflow and minus_uflow in expected results.
* math/libm-test.inc (scalbn_test_data): Add more tests of
negative arguments. Use plus_oflow, minus_oflow, plus_uflow and
minus_uflow.

(scalbln_test_data): Add more tests of negative arguments. Use
plus_oflow, minus_oflow, plus_uflow and minus_uflow.
(scalbln_test): Use ALL_RM_TEST.

This patch continues the libm-test move towards automatic testing of
all test inputs in all rounding modes by adding gen-libm-test.pl
support for tests specifying results in each rounding mode manually.
Previously a TEST_* line could specify arguments and results, or
arguments, results and flags. Now there is the option of (arguments,
results-rd, flags-rd, results-rn, flags-rn, results-rz, flags-rz,
results-ru, flags-ru). This is used to replace the separate arrays of
results in each rounding mode for lrint, llrint and rint. (In the
case of rint, some tests were only in rint_test_data and needed to
have expectations for non-default rounding modes added, which I did
manually. In various cases there were slight differences in things
such as the ordering of tests in the arrays for each mode.)
Tested x86_64 and x86.
* math/gen-libm-test.pl (parse_args): Handle results specified for
each rounding mode separately.
* math/libm-test.inc (lrint_test_data): Merge in per-rounding-mode

At present, libm-test.inc tests are run in multiple rounding modes by
having a separate array for each rounding mode (which might or might
not have the same test inputs as the other such arrays), a separate
function calling a RUN_TEST_LOOP_* macro over that array, and a
separate call to that function in main. The number of functions
tested in multiple rounding modes has gradually increased as
rounding-mode-specific bugs have been found and fixed in different
functions.
It would be better to be able to use a single macro call, in a single
function, to run tests for a function over all rounding modes, with
this being done for all libm functions except in cases where it's
deferred until some bugs can be fixed because XFAILing all affected
tests would be painful (that's why the full set of pow tests isn't
currently run in all rounding modes). This patch helps prepare for
that by making the structures storing expected results for tests store
results for all four rounding modes. After this patch, the results
for all modes are just duplicates, but tests access the appropriate
field in the structure, so helping to pave the way for when the fields
stop being duplicates and multiple rounding modes can be tested from a
single array. Tests might in future specify a single set of results,
to be used in all rounding modes; separate results for each rounding
mode, specified manually; or use of auto-libm-tests-* to generate
results for each rounding mode.

This patch changes gen-auto-libm-tests so that, when generating test
results that depend on whether the architecture has before-rounding or
after-rounding tininess detection, the :before-rounding or
:after-rounding conditions go on the exception / errno flags
generated, rather than generating two separate lines in
auto-libm-test-out for e.g. flt-32:before-rounding and
flt-32:after-rounding.
The rationale for this is as follows. It would be desirable for
testing a libm function in all rounding modes to require just one
function and array in libm-test.inc, not four (or five), with the
array of test data including expected results for all rounding modes
rather than separate arrays for each rounding mode that also need to
repeat all the test inputs. For gen-libm-test.pl to generate data for
such an array from auto-libm-test-out, it would be helpful if each
(format, test input) pair has exactly four lines in
auto-libm-test-out, one for each rounding mode, rather than some
rounding modes having just one line and some having two because the
exceptions depend on tininess detection.
Tested x86_64 and x86.

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).

math/gen-libm-test.pl has code to beautify names of various constants,
transforming the source form in libm-test.inc into the version
appearing in test names in libm-test-ulps files.
This has become decreasingly relevant over time for the M_* constants,
first as I changed the test names so only the arguments and not the
expected results appeared in them, then as tests have moved to
auto-libm-test-* so that automatically generated hex float constants
get used instead of M_* in test inputs.
This patch removes the beautification for all M_* constants. Tested
x86_64 and x86 and ulps updated accordingly. Even the one case where
this affected the name in the ulps files will disappear once complex
function tests are moved to auto-libm-test-*.
