Andreas Schwab and John Baldwin pointed out some bugs in the header sorting patch; and I noticed that the output was not correct when limited to a subset of files (a bug in my script). So, I'm reverting the patch. I may try again after fixing the issues pointed out. gdb/ChangeLog 2019-04-05 Tom Tromey <tom@tromey.com> Revert the header-sorting patch. * ft32-tdep.c: Revert. * frv-tdep.c: Revert. * frv-linux-tdep.c: Revert. * frame.c: Revert. * frame-unwind.c: Revert. * frame-base.c: Revert. * fork-child.c: Revert. * findvar.c: Revert. * findcmd.c: Revert. * filesystem.c: Revert. * filename-seen-cache.h: Revert. * filename-seen-cache.c: Revert. * fbsd-tdep.c: Revert. * fbsd-nat.h: Revert. * fbsd-nat.c: Revert. * f-valprint.c: Revert. * f-typeprint.c: Revert. * f-lang.c: Revert. * extension.h: Revert. * extension.c: Revert. * extension-priv.h: Revert. * expprint.c: Revert. * exec.h: Revert. * exec.c: Revert. * exceptions.c: Revert. * event-top.c: Revert. * event-loop.c: Revert. * eval.c: Revert. * elfread.c: Revert. * dwarf2read.h: Revert. * dwarf2read.c: Revert. * dwarf2loc.c: Revert. * dwarf2expr.h: Revert. * dwarf2expr.c: Revert. * dwarf2-frame.c: Revert. * dwarf2-frame-tailcall.c: Revert. * dwarf-index-write.h: Revert. * dwarf-index-write.c: Revert. * dwarf-index-common.c: Revert. * dwarf-index-cache.h: Revert. * dwarf-index-cache.c: Revert. * dummy-frame.c: Revert. * dtrace-probe.c: Revert. * disasm.h: Revert. * disasm.c: Revert. * disasm-selftests.c: Revert. * dictionary.c: Revert. * dicos-tdep.c: Revert. * demangle.c: Revert. * dcache.h: Revert. * dcache.c: Revert. * darwin-nat.h: Revert. * darwin-nat.c: Revert. * darwin-nat-info.c: Revert. * d-valprint.c: Revert. * d-namespace.c: Revert. * d-lang.c: Revert. * ctf.c: Revert. * csky-tdep.c: Revert. * csky-linux-tdep.c: Revert. * cris-tdep.c: Revert. * cris-linux-tdep.c: Revert. * cp-valprint.c: Revert. * cp-support.c: Revert. * cp-namespace.c: Revert. * cp-abi.c: Revert. * corelow.c: Revert. * corefile.c: Revert. * continuations.c: Revert. * completer.h: Revert. * completer.c: Revert. * complaints.c: Revert. * coffread.c: Revert. * coff-pe-read.c: Revert. * cli-out.h: Revert. * cli-out.c: Revert. * charset.c: Revert. * c-varobj.c: Revert. * c-valprint.c: Revert. * c-typeprint.c: Revert. * c-lang.c: Revert. * buildsym.c: Revert. * buildsym-legacy.c: Revert. * build-id.h: Revert. * build-id.c: Revert. * btrace.c: Revert. * bsd-uthread.c: Revert. * breakpoint.h: Revert. * breakpoint.c: Revert. * break-catch-throw.c: Revert. * break-catch-syscall.c: Revert. * break-catch-sig.c: Revert. * blockframe.c: Revert. * block.c: Revert. * bfin-tdep.c: Revert. * bfin-linux-tdep.c: Revert. * bfd-target.c: Revert. * bcache.c: Revert. * ax-general.c: Revert. * ax-gdb.h: Revert. * ax-gdb.c: Revert. * avr-tdep.c: Revert. * auxv.c: Revert. * auto-load.c: Revert. * arm-wince-tdep.c: Revert. * arm-tdep.c: Revert. * arm-symbian-tdep.c: Revert. * arm-pikeos-tdep.c: Revert. * arm-obsd-tdep.c: Revert. * arm-nbsd-tdep.c: Revert. * arm-nbsd-nat.c: Revert. * arm-linux-tdep.c: Revert. * arm-linux-nat.c: Revert. * arm-fbsd-tdep.c: Revert. * arm-fbsd-nat.c: Revert. * arm-bsd-tdep.c: Revert. * arch-utils.c: Revert. * arc-tdep.c: Revert. * arc-newlib-tdep.c: Revert. * annotate.h: Revert. * annotate.c: Revert. * amd64-windows-tdep.c: Revert. * amd64-windows-nat.c: Revert. * amd64-tdep.c: Revert. * amd64-sol2-tdep.c: Revert. * amd64-obsd-tdep.c: Revert. * amd64-obsd-nat.c: Revert. * amd64-nbsd-tdep.c: Revert. * amd64-nbsd-nat.c: Revert. * amd64-nat.c: Revert. * amd64-linux-tdep.c: Revert. * amd64-linux-nat.c: Revert. * amd64-fbsd-tdep.c: Revert. * amd64-fbsd-nat.c: Revert. * amd64-dicos-tdep.c: Revert. * amd64-darwin-tdep.c: Revert. * amd64-bsd-nat.c: Revert. * alpha-tdep.c: Revert. * alpha-obsd-tdep.c: Revert. * alpha-nbsd-tdep.c: Revert. * alpha-mdebug-tdep.c: Revert. * alpha-linux-tdep.c: Revert. * alpha-linux-nat.c: Revert. * alpha-bsd-tdep.c: Revert. * alpha-bsd-nat.c: Revert. * aix-thread.c: Revert. * agent.c: Revert. * addrmap.c: Revert. * ada-varobj.c: Revert. * ada-valprint.c: Revert. * ada-typeprint.c: Revert. * ada-tasks.c: Revert. * ada-lang.c: Revert. * aarch64-tdep.c: Revert. * aarch64-ravenscar-thread.c: Revert. * aarch64-newlib-tdep.c: Revert. * aarch64-linux-tdep.c: Revert. * aarch64-linux-nat.c: Revert. * aarch64-fbsd-tdep.c: Revert. * aarch64-fbsd-nat.c: Revert. * aarch32-linux-nat.c: Revert.
