Hi, while looking into Zen tuning I noticed that some of the tunables in x86-tune.def was added into section with obsolette flags, which does not make much sense. * x86-tune.def (X86_TUNE_AVOID_FALSE_DEP_FOR_BMI, X86_TUNE_ADJUST_UNROLL, X86_TUNE_ONE_IF_CONV_INSN): Move to right

[patch, Fortran] Fix PR 82372

Hello world, the attached patch displays an error for characters which are outside the normal Fortran character set, and includes a hex code when it is not printable. gfortran 4.9 did display unprintable characters in the file, so it might be argued that this bug is a regression.

GCC 7 libbacktrace patch committed: Ignore compressed debug sections

This patch to the GCC 7 libbacktrace ignores compressed debug sections. If we don't, the DWARF reader reports an error. Since the GCC 7 libbacktrace does not support uncompressing the debug sections, ignoring them is the best approach (on trunk, we uncompress). This is for PR 80914.
