msys2/mingw64 build failure (a-except.adb) #7

Closed Alex-Gamper closed 4 years ago

Hi AdaCore

The latest build of the Ada runtime has now regressed with the latest git version under msys2/mingw64. Below is the error that I am seeing. I got around it by setting the optimization to -O0 for a-except in makefile.rtl. Not sure if this is an optimal solution, But I thought it relevant to bring to your attention. Notice that the last -O1 I think overrides any previous setting ?

Thanks Alex

You need to do an svn update on llvm-interface/gnat_src. In general every time you update GNAT LLVM sources you should also update the gnat_src directory since sometimes synchronized changes are done in both repositories.

Understood, and gnat-llvm now builds cleanly, thanks for your great effort !

Great, thanks for confirming.
