I am not familiar with the details but if you put
into an FTN95 program then the kind value is out of range unless you are using /alt_kinds. Otherwise default values are in the range 1 to 4. |

It looks like you are correct, 64-bit constants are truncated to 32-bit (in sdbg and sdbg64). I will look at it. |

Paul,
thanks for your hint, I tried it and command Code: |
ftn95 sdbg_problem1.for /alt_kinds /debug /64 /link
|
did not produce the error any more (having added _8 to the constants of the assignments to idum8 and idum88 in the ftn95 code mentioned above).
Regards,
Dietmar |

It would be safer to avoid /alt_kinds and append _4 (for example).
Hopefully all the bugs relating to /alt_kinds have now been fixed but I am not that confident. |

Currently I am using sdbg64 quite often when porting a GUI application from 32 to 64 bit. I happened to run into a subroutine containing ENTRY statements und unfortunately could not set breakpoints in the lines after the entry statements. This works for the 32 version of ftn95/sdbg.
Please look at file myentry_subroutine.for
Code: |
INTEGER*4 MYINT,MYRESULT
MYINT=33
call SR1(MYINT,MYRESULT)
write(*,*) MYRESULT
call SR2(MYINT,MYRESULT)
write(*,*) MYRESULT
call SR3(MYINT,MYRESULT)
write(*,*) MYRESULT
end
SUBROUTINE SR1( MYINT,MYRESULT )
INTEGER*4 MYINT,MYRESULT
MYRESULT = MYINT
RETURN
ENTRY SR2 ( MYINT,MYRESULT )
MYRESULT = 3 * MYINT
RETURN
ENTRY SR3 ( MYINT,MYRESULT )
MYRESULT = MYINT + 1
RETURN
END
|
and compile it via
Code: |
ftn95 myentry_subroutine.for /debug /link /64
|
I may set a breakpoint to line 16, however, I cannot set breakpoints a lines 20,21,23 and 24 which I should be able to, shouldn't I?
Regards,
Dietmar |

I would add similar problem that SDBG64 as opposed to SDBG starts its debugging process at the wrong first line (red line). To reproduce that one can use Polyhedron test suite of Fortran-90 benchmarks which is free for downloading. Take the smallest size fortran sources like channel2.f90 or tfft2.f90 |

Curious is company aware of a lot of work that needs the SDBG64? It is like in deep beta state. Still a lot of crashes with not identified by the compiler exceptions, the whole subroutines of tens of thousands of lines may not allow to set a single debug breakpoint...Try using /CHECK and see that yourselves.
And what was surprising in its reliability is that compared to SDBG it is like one step forward ten steps back. Was it completely rewritten from zero by some reason? I did not re-write my codes when moved to 64bits, all what was necessary is just minor almost cosmetic changes.
I do not find explanation for the devilry that FTN95 was probably the only software which moved to 64 bit so painfully. The entire world switched to 64 and no one even noticed be it processors, OSes, even mobile phones with all their billion apps. The only explanation i see, continuing football theme started by John-S, is some difference with others: Salford is the home of famous Manchester United which is like a heavy drug for their fans ![Smile](images/smiles/icon_smile.gif) |

Oy !!!!! less of the insults please.
First, I don't think Silverfrost are actually embedded in the City (yes it's a city !) of Salford anymore, more likely in the leafy southern suburbs or the bustling re-generated town centre.
Maybe someone could shed some light on where HQ actually is these days ?
Or should that be 'light up the shed' which is current day HQ
More importantly, the subtle difference between 'Old Trafford' and 'Silverfrost HQ' is that one is the 'Theatre of Dreams' ... the other is 'The Theatre of Screams' !!!! LOL :O)
... but of course we shouldn't expect those living in the land of 'world series soccer' to understand the significance of god's mown pasture ... hence why we've been living under the guise of being technically the richest club in the universe whilst actually being perpetually on the verge of being bankrupt !
Manchester is RED. SAFRA. LUHG. TPOAE. COTN. simply put, they're the Georgie Best, god rest his soul ![Smile](images/smiles/icon_smile.gif) _________________ ''Computers (HAL and MARVIN excepted) are incredibly rigid.

I now pose a question to Paul, Robert and David .... just one word answer required ......... RED ? or Blue ?

oh dear, oh dear dear ..... oh dear dear dear ..... next time you're in Manchester robert , just go up to random people and ask 'are you red or blue' ! _________________ ''Computers (HAL and MARVIN excepted) are incredibly rigid.
