Added ilaenv2stage.f to enable the extraction of 2stage machine dependent variables from the 2stage solver without having to rely on compiling the entire library with the recursive flag. Secondly, all calls to ILAENV( 17 <= 21, ...) have been fixed to use the corresponding ILAENV2STAGE routine by translating ISPEC by -16 I.e. ILAENV( 17, ...) == ILAENV2STAGE( 1, ...) Also fixed the documentation of ilaenv.f to specify the cases of ISPEC > 16. Signed-off-by: Nick Papior <nickpapior@gmail.com>
This required an overloaded ilaenv2stage in the ilaenv.f in the test directories to use the PARMS(1) for ISPEC == 17. Signed-off-by: Nick Papior <nickpapior@gmail.com>
They called with DSY* and thus the block-sizes were not selected for complex numbers. Signed-off-by: Nick Papior <nickpapior@gmail.com>

@langou gentle ping, could you please comment on whether this seems like a good idea or not? My main motivation was the removal of the If this has no interest I can make a new PR with the fixes for the |

Hi Nick, I was waiting on some feedback for some stakeholders in your fix. I did not hear from them. So this is all good. Yes, thanks for the fix. I do agree that this is better like this. Thanks for the PR. Cheers, Julien. |

Great it could be of use. You are welcome. :) |

Yes, however in http://icl.cs.utk.edu/lapack-forum/viewtopic.php?t=1930#p5457 Julien explains that only using the correct stack size solves the problem (i.e. without frecursive), so I guess it is not really related to that flag. |

I see now that the recursive flag is for exactly that bug. It should be re-added. |

@pv I have made a PR to fix this, thanks for noticing. |
There were some missing ILAENV -> ILAENV2STAGE conversions missing. This commit fixes all calls to ILAENV that uses the parameters 17, 18, 19, 20 (the old ILAENV). I have also tested this for the issue reported in Reference-LAPACK#262. Signed-off-by: Nick Papior <nickpapior@gmail.com>

The
ILAENVroutine forces the entire LAPACK library to be compiled with-frecursiveor the equivalent for non-GNU compilers.This merge fixes this by adding a separate
ILAENV2STAGEroutine to query information related to the 2stage solvers, only.I.e. there are now 2
ILAENVroutines for retrieving machine dependent variables.Secondly, this merge fixes
ILAENVfor the 2stage routines[CZ]HEEVRfor their block-size queries (DSY*was used). I know this should have went in another PR, but that would inflict with this PR.Tests are also updated to enable these changes.
