I don't have a long doubles smoker that doesn't also build with -DDEBUGGING and -Dusethreads, but I suspect that a build with -Duselongdoubles is sufficient to trigger this. Full build log here​: http​://73.193.221.114​:8010/#/builders/15/builds/42

In fact, these test failures were added by several of those commits - they do not bisect cleanly. For example​:

But more failing tests are added over the next few commits. If I understand the original bugs correctly, I think the issue was fixed for normal builds, but your tests have uncovered that the same problem still exists for long doubles.

Not quite. The failures you are seeing are caused by your long doubles (x86 80-bit) being scaled differently​:

  perl -wle 'printf "%a\n", -1.5' # IEEE 754 64-bit
  -0xcp-3
  perl -wle 'printf "%a\n", -1.5' # x86 80-bit
  -0x1.8+0

In any system​:

  perl -wle 'print -0x1.8p+0'
  -1.5
  perl -wle 'print -0xcp-3'
  -1.5

I'll extend the block that limits the testing only for the expected systems, sorry about not
catching that earlier.

The RT System itself - Status changed from 'new' to 'open'

The -Dcc='ccache gcc-6' is not necessary, either. I triggered failures with simply '-des -Dusedevel -Duselongdouble'. See attachments.

Thank you very much.

Not quite. The failures you are seeing are caused by your long
doubles (x86 80-bit) being scaled differently​:

perl -wle 'printf "%a\n", -1.5' # IEEE 754 64-bit
-0xcp-3
perl -wle 'printf "%a\n", -1.5' # x86 80-bit
-0x1.8+0

Duh. Got the comments the wrong way round.

perl -wle 'printf "%a\n", -1.5' # x86 80-bit
-0xcp-3
perl -wle 'printf "%a\n", -1.5' # IEEE 754 64-bit
-0x1.8+0

This different scaling is seen on any long-double build, consistently
since %a support was added. It's obviously based on arranging for
the significand to end in the low-order bit of a hex digit, rather than
arranging for the integer part of a normalised significand to always be 1.
This is legal per the C spec, and glibc does the same. This behaviour
minimises the number of required digits, and aligns the digits with the
bitwise structure of the long double type. The other behaviour better
matches the numerical structure. I think the other behaviour would be
better, but this behaviour isn't a bug.

The tests failing is a bug. The tests obviously need to allow for the
variation in behaviour.

... consistent with how the said platforms' libcs do it. Not just glibc.

I disagree with your use of the word since this is a platform difference,
but whatever.
