Fortran compiler
A few years ago I started converting a large old Fortran program which I had running on an IBM 7040 and then on a 360. I have a copy of Lahey Fortran and ran into a compiler bug and gave up on it. How can I download your compiler and get documentation. I don't understand what I've read on the internetThanksElliot Sent from AT&T Yahoo Mail on Android
Re: [PATCH v2] fortran: Detect duplicate unlimited polymorphic types [PR103662]
Hi Mikael, Am 22.04.22 um 12:53 schrieb Mikael Morin: Le 21/04/2022 à 23:14, Mikael Morin a écrit : Hello, this is a fix for PR103662, a TBAA issue with unlimited polymorphic types. I attached a draft patch to the PR which was accumulating all unlimited polymorphic symbols to a single namespace, avoiding duplicate symbols and thus eliminating the problem. After reviewing the code more in detail, I was afraid that some symbols could still end up in the local namespace, and that the problem would remain for them after all. Despite not being able to generate a testcase where it happened, I decided to produce a patch based on Jakub’s analysis in the PR audit trail, as that way supports duplicates by design. On top of Jakub’s patch, there are a couple more types registrations just in case (they handle duplicates so that’s fine), and the type comparison fix that he was too fortran-uncomfortable to do. The testcase had to be fixed as we found out in the PR audit trail. Regression tested on x86_64-pc-linux-gnu. OK for master? Mikael I have read Jakub’s analysis again, and it says the type registration is useless for unlimited polymorphic fake symbols, as they are all translated as ptr_type_node. So it can be dropped, which brings this v2 patch closer to Jakub’s original. Regression tested again. OK? LGTM. Thanks for the patch! Harald

I need a fortran frontend ack as well. Looks good to me. Thanks a lot for taking this on! This would have been a serious regression if released with gcc 12. Best regards Thomas
Re: Fortran compiler
Elliot, Let me know what system you want the compiler to run on? Linux, Windows, PowerPC? I can guide you through installing on some of these. Usually we build it from source. However, many linux distributions have packages you can install easily.
