/* Interface to coff-pe-read.c (portable-executable-specific symbol reader).
Update copyright year range in all GDB files. This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

Don't include gdbarch.h from defs.h I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.

/* Read the export table and convert it to minimal symbol table
entries */
Record minimal symbols directly in reader. This patch changes minimal symbol creation in two ways. First, it removes global variables in favor of members of minimal_symbol_reader. Second, it changes functions like prim_record_minimal_symbol to be member functions of minimal_symbol_reader. 2016-10-21 Tom Tromey <tom@tromey.com> * xcoffread.c (record_minimal_symbol, scan_xcoff_symtab): Add "reader" argument.
