Flag -d=bltdump does not produce any output anymore

[Adrian Pop]

It seems that -d=bltdump does not produce any output since 1.14.

Reported here:

front-end

Any way to bring this back?

[Andreas Heuermann]

The bltdump itself is working fine (tested on Windows 10, 64 bit 1.14.0, 1.14.1 and 1.16.0-dev). It simply doesn't produce any output for examples without index reduction, like for the BouncingBall example.

The name is misleading, since it is more a index-reduction dump, but that is what the users are used to. We could add some message if nothing was dumped, but wouldn't bother for v1.14

I haven't checked why it dumped some output on v1.13.2.

-d=dumpindxdae will get the same informations that the "old" bltdump was giving.

Replying to AnHeuermann:

The name is misleading, since it is more a index-reduction dump, but that is what the users are used to. We could add some message if nothing was dumped, but wouldn't bother for v1.14

Would be nice to have in 1.16.0, if you bother to do that.

[Francesco Casella]

Retargeted to 1.17.0 after 1.16.0 release

[Francesco Casella]

Retargeted to 1.18.0 because of 1.17.0 timed release.

[Francesco Casella]

Ticket retargeted after milestone closed
