Re: [Patch, Fortran, committed] PR 50585: [4.6/4.7 Regression] ICE with assumed length character array argument


Hi Janus,

I completely missed that this patch is still pending review as you wrote "committed". However, it only applied to the ICE and not to the documentation and backporting.

I have just committed as obvious a one-line patch to fix a regression

Should I backport to 4.6? And also to 4.5?

Yes, please backport to 4.6. If you want, you can also backport to 4.5. However, I do not think that -fwhole-file gets used in 4.5 - especially, as it has some issues.


Moreover, I noticed that
http://gcc.gnu.org/onlinedocs/gcc-4.6.1/gfortran/Code-Gen-Options.html#Code-Gen-Options
falsely claims that -fwhole-file is not used by default (which it is
since 4.6, see http://gcc.gnu.org/gcc-4.6/changes.html). Attached is a
small documentation patch to fix this. Ok to apply to trunk and 4.6?

OK. By the way, I was thinking of completely removing that option. -fwhole-file avoids some wrong-code issues, generates faster code, and improves diagnostic. Thus, there is no real reason* of keeping -fno-whole-file. Thus, I would like to deprecate the option. (* = one reason is to see whether a bug is due to this flag, but that does not really help with fixing the issue.)


I think your wording is fine, I still wonder whether one should somehow imply more clearly that -fno-whole-file is not recommended and that the whole flag is deprecated.

PS: I think except for procedure calls where the explicit interface is not known, gfortran generates finally the correct declaration for the middle end. At least I have not encountered any multiple-declaration issues for a long time!
