--- Comment #30 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- (In reply to jos...@codesourcery.com from comment #29) > I don't see the issue building glibc with build-many-glibcs.py any more, > hence it no longer uses -fno-isolate-erroneous-paths-dereference > -fno-isolate-erroneous-paths-attribute for SH. Is this particular patch part of glibc_2.25? We still need the __builtin_trap() for the kernel in any case which is why the issue was recently brought up again. Without the patch, it's not possible to build the kernel with gcc-7.
