Iain Buclaw f49692dff8 Make fputs_unfiltered use fputs_maybe_filtered 
This patch redefines fputs_unfiltered in utils.c, with new behavior to
forward parameters to fputs_maybe_filtered.  This makes
fputs_unfiltered identical to fputs_filtered, except filtering is
disabled.

Some callers of fputs_unfiltered have been updated to use ui_file_puts
where they were using other ui_file_* functions anyway for IO.

This fixes the problem I saw with \032\032post-prompt annotation being
flushed to stdout in the wrong order.

Iain Buclaw ff491e6bfc Make gdb_flush also flush the wrap buffer 
This changes gdb_flush to also flush the internal wrap buffer.  A few
places needed to continue using the previous approach, so this also
introduces ui_file_flush for those.

Sergio Durigan Junior 1aa93c3a9b Implement '--enable-src-release-build' option and make src-release.sh use it 
The generation of snapshots has been broken since we've disable
in-tree builds for GDB.  Given that src-release.sh performs a build
before creating the release tarball, and that this build is performed
in-tree, the solution we found is to implement a new top-level
configure flag called '--enable-src-release-build' which disables the
in-tree build restriction, and then make src-release.sh use it.

Eli Zaretskii 50500ecfef libctf: compilation failure on MinGW due to missing errno values 
This commit fixes a compilation failure in a couple of libctf files
due to the use of EOVERFLOW and ENOTSUP, which are not defined
when compiling on MinGW.

libctf/ChangeLog:

	PR binutils/25155:
	* ctf-create.c (EOVERFLOW): If not defined by system header,
	redirect to ERANGE as a poor man's substitute.
	* ctf-subr.c (ENOTSUP): If not defined, use ENOSYS instead.

This one is how Eli implemented it. I think this implementation
has a weakness in the following sense: If other units in libctf
start using those constants, we'll get the same error again.
Also, I'm wondering whether their use is documented as part of
the official libtcf API or not -- users might be writing code
that tests for these, and if the system doesn't support them,
how would they know what errno code to use in its place. This
argues for a having that information in one of libctf's header
files. I think it would be nice to have those in ctf-decls.h,
but I think we'll need to include <errno.h> in ctf-decls.h if
we decide to define those macros there.

Rather than second-guess what the CTF developers would prefer,
I'm starting by sending Eli's patch, to see what you guys think.

Thanks,

Hannes Domani 42cce0e4fc Fix library segment-address for 64bit values

Joel Brobecker 043a001093 Abort configure immediately if building GDB in tree 
The move of gnulib to the top src directory is causing the GDB build
to break if configured in tree. We hope to lift that limitation at
some point but, in the meantime, this commit allows us to abort
the initial configure right away with a clear error message should
the user attempt to build in tree.

ChangeLog:

        * configure.ac: Abort the build with an error if trying to build
        GDB in tree.
        * configure: Regenerate.

Christian Biesinger 975292a976 Don't define _FORTIFY_SOURCE on MinGW 
Recent MinGW versions require -lssp when using _FORTIFY_SOURCE, which
gdb does (in common-defs.h)
https://github.com/msys2/MINGW-packages/issues/5868#issuecomment-544107564

To avoid all the complications with checking for -lssp and making sure it's
linked statically, just don't define it.

Tom Tromey 3c473fad8f Add constructor to stap_static_probe_ops 
PR build/24937 concerns an error given by the clang provided by a
particular version of macOS.  In particular, it reports

    error: default initialization of an object of const type 'const
    stap_static_probe_ops' without a user-provided default constructor

Although (at least according to sources I found online) this was
resolved as a bug in the standard, it seemed simple enough to work
around this.

Given that this is a trivial build fix, I think it should go on the
gdb 9 branch as well.

2020-01-07  Tom Tromey  <tromey@adacore.com>

	PR build/24937:
	* stap-probe.c (class stap_static_probe_ops): Add constructor.

Andrew Burgess f7da8e5b9b gdb: Fix backtrace with disassemble-next-line on 
In this commit:

  commit ec8e2b6d30
  Date:   Fri Jun 14 23:43:00 2019 +0100

      gdb: Don't allow annotations to influence what else GDB prints

A change was accidentally made that moved a call to do_gdb_disassembly
out of an if block guarded by 'if (source_print && sal.symtab)'.  The
result was that if a user has 'set disassemble-next-line on' then the
backtrace would now include some disassembly of a few instructions in
each frame.

This change was not intentional, but was not spotted by any tests.

This commit restores the old behaviour and adds a test to ensure this
doesn't break again in the future.

gdb/ChangeLog:

	* stack.c (print_frame_info): Move disassemble_next_line code
	inside source_print block.

gdb/testsuite/ChangeLog:

	* gdb.base/backtrace.c: New file.
	* gdb.base/backtrace.exp: New file.

Eli Zaretskii 84baa6a515 libctf: Add configure check for asprintf (for MinGW) 
This commit fixes a compilation warning when compiling libctf
on MinGW:

    libctf/ctf-dump.c:118:8: warning: implicit declaration of function
    'asprintf'; did you mean 'vasprintf'? [-Wimplicit-function-declaration]

	 if (asprintf (&bit, " %lx: [slice 0x%x:0x%x]",
	     ^~~~~~~~
	     vasprintf

MinGW doesn't provide that function, so we depend on the one provided
by libiberty. However, the declaration is guarded by HAVE_DECL_ASPRINTF,
which we do not have in libctf's config.h.

libctf/ChangeLog:

	PR binutils/25155:

Tom Tromey 4ae7258edf Fix pthread_setname_np build error 
My earlier patch to fix the pthread_setname_np build error on macOS
was incorrect.  While the macOS man page claims that
pthread_setname_np returns void, in <pthread.h> it is actually
declared returning "int".  I knew this earlier, but must have made
some mistake when preparing the patch for submission (perhaps when
removing the templates?).

This patch re-fixes the bug.  I'm also applying it to the 9.1 branch.

Tested by building on macOS High Sierra.

Tom Tromey 1c66314dcb Fix build failure on macOS 
PR build/25250 notes that the gdb 9 pre-release fails to build on
macOS, due to a name clash between field_kind::STRING and the STRING
token in ada-exp.y.  I am not sure (I couldn't reproduce this myself),
but presumably this is due to differences caused by the version of
bison in use there.

This patch works around the problem by renaming the field_kind
enumerator.  I chose to rename this one because it is used in
relatively few places -- it's just an implementation detail of the
style code.

This version also renames field_kind::SIGNED for consistency.

Let me know what you think.  I intend to check this in on the gdb 9
branch as well.

Simon Marchi be19b69991 Fix double-free when creating more than one block in JIT debug info reader 
A double-free happens when using a JIT debug info reader that creates
more than one block.  In the loop that frees blocks in finalize_symtab,
at the very end, the gdb_block_iter_tmp variable is set initially, but
not changed as the loop advances.  If we have two blocks, the first
iteration frees the first block, the second iteration frees the second
block, but the third iteration tries to free the second block again, as
gdb_block_iter_tmp keeps pointing on the second block.

Fix it by assigning the gdb_block_iter_tmp variable in the loop.

I have improved the jit-reader.exp test to cover this case, by adding a
second "JIT-ed" function and creating a block for it.  I have renamed
the existing function to something I find a bit more descriptive.  There
are no significant changes to jit-reader.exp itself, only updates
following the renaming.  The important changes are in jithost.c
(generate a new function) and in jitreader.c (create a gdb_block for
that function).

This was found because of an ASan report:

DOS executable program before the coff image to load it in memory
and execute it. This is needed, because DOS cannot run coff files.
The COFF image is loaded in memory without the stub attached, so
all offsets are relative to the beginning of the image, not the
actual file. We handle this in bfd by setting bfd->origin to where
the COFF image starts. */
All the functions below are called by the corresponding functions
from coffswap.h.
The only thing what they do is to adjust the information stored in
the COFF file which are offset into the file.
This is needed, because DJGPP uses a very special way to load and run
the coff image. It loads the image in memory and assumes then, that the
image had no stub by using the filepointers as pointers in the coff
image and NOT in the file.
To be compatible with any existing executables I have fixed this
here and NOT in the DJGPP startup code. */
