417f648842 Tests for cancellation in fma(). Also include more tests for 128-bit 
long doubles. Thanks for clusteradm (simon) for making the needed
hardware available.

31b4d3aef3 Add some tests for corner cases of log() in unusual rounding modes. 
I wrote these ages ago, but they've been failing until now.

9c7781b7a3 Add some tests for double-rounding bugs in fma(). 2011-10-15 05:26:16 +00:00

2dc9da4376 Add some tests for cexp() and cexpf(). (I need to clean up all of 
these tests some day, but in the mean time, they're a useful sanity
check for future changes.)

cf37ce3724 signbit() returns nonzero for negative arguments, but we shouldn't assume 
that it always returns the same nonzero value.

d7b27f3d13 Add tests for conj{,f,l}() that I wrote some time ago. These test the 
versions in libm, not the gcc builtins.

8bb8d6397d Add regression tests for fmin{,f,l} and fmax{,f,l}. 
I wrote these to test amd64 asm functions that used
maxss, maxsd, minss, and minsd, but it turns out that
those instructions don't handle NaNs and signed zero
in the same way as fmin() and fmax() are required to,
so we're stuck with the C versions for now.

e5af135aad Add some regression tests for libm's exponential functions. These 
mostly just test corner cases rather than accuracy. Some of the
tests don't pass right now if you compile libm at -O2 due to gcc
constant-folding some things that it shouldn't. I'll fix that
shortly.

dd00a42722 Tests for lrintl() and llrintl(). I didn't add anything specially 
tailored for the long double format; instead, I just modified the existing
tests to test lrintl() and llrintl() as well.

3f7112a1f4 Don't try the long double tests on i386. Our reduced precision 
can cause them to fail.

a468cce785 Fixes to avoid overzealous constant folding. 2007-12-09 20:56:08 +00:00
David Schultz
4e97f925b6 gcc 4 does some overzealous constant folding, and since it doesn't 
support FENV_ACCESS, that was causing this test to fail. Use a volatile
to avoid the constant folding.

565b7c794f - Replace fe[gs]etmask() with feenableexcept(), fedisableexcept(), and 
fegetexcept().
- Add additional tests for the above.
- Output a separate success message for each of the 8 components of
  this set of tests.

00e13b1d67 Switch over to a different, more flexible test output protocol that's 
understood by Perl's Test::Harness module and prove(1) commands.

Update README to describe the new protocol.  The work's broken down into
two main sets of changes.

First, update the existing test programs (shell scripts and C programs)
to produce output in the ok/not ok format, and to, where possible, also
produce a header describing the number of tests that are expected to be
run.

Second, provide the .t files that actually run the tests.  In some cases
these are copies of, or very similar too, scripts that already existed.
I've kept the old scripts around so that it's possible to verify that
behaviour under this new system (in terms of whether or not a test fails)
is identical to the behaviour under the old system.

Add a TODO file.

proper rounding mode as well.
