Blocking dlang/dmd#10872

[dlang-bot]

Thanks for your pull request and interest in making D better, @Luhrel! We are looking forward to reviewing it, and you should be hearing from a maintainer soon.
Please verify that your PR follows this checklist:

• My PR is fully covered with tests (you can see the coverage diff by visiting the details link of the codecov check)
• My PR is as minimal as possible (smaller, focused PRs are easier to review than big ones)
• I have provided a detailed rationale explaining my changes
• New or modified functions have Ddoc comments (with Params: and Returns:)

Please see CONTRIBUTING.md for more information.

Testing this PR locally

If you don't have a local development environment setup, you can use Digger to test this PR:

dub run digger -- build "master + druntime#2972"

I don't see any changes in any tests, how can that be?

[thewilsonator]

Because this is blocking a dmd PR and NFC. The tests are in that.

Note that the first diff is used in assert messages so any change will show up. If that isn't covered by tests I'd be surprised.

The second one is for debug only.

There is one test, but it does not include real:

druntime/test/exceptions/src/assert_fail.d

Lines 62 to 67 in b57ca7c

	void testFloatingPoint()()
	{
	test(1.5, 2.5, "1.5 != 2.5");
	test(float.max, -float.max, "3.40282e+38 != -3.40282e+38");
	test(double.max, -double.max, "1.79769e+308 != -1.79769e+308");
	}

Please use another constant, real isn't 80-bit for most targets.

[Luhrel]

Maybe this way ?

import std.conv : to;
//test(real.max, -real.max, "1.18973e+4932 != -1.18973e+4932");
test(real.max, -real.max, real.max.to!string ~ " != -" ~ real.max.to!string);

How shall I test this with a number which change depending of the platform ?

[kinke]

Well, real.max seems totally arbitrary, so any nicely representable value should do (5.25L or whatever). std.conv.to is in Phobos and so not suited for a druntime test.

[Luhrel]

Changed to:

test(5.25L, -5.25L, "5.25 != -5.25");

[Luhrel]

Changed to:

test(5.25L, -5.25L, "5.25 != -5.25");

Somehow it returns this:

'-nan != -nan' != '5.25 != -5.25'

Any idea @kinke @Geod24 ?
