* Remove redundant include directives.Gary Benson2015-06-241-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stdint.h was added to common-defs.h some months ago and should no longer be included directly by any file. gdb_assert.h was added to common-defs.h nearly a year ago, but three includes have crept in since then. This commit removes all such redundant include directives. gdb/ChangeLog: * common/buffer.c (stdint.h): Do not include. * common/print-utils.c (stdint.h): Likewise. * compile/compile-c-symbols.c (gdb_assert.h): Likewise. * compile/compile-c-types.c (gdb_assert.h): Likewise. * ft32-tdep.c (gdb_assert.h): Likewise. * guile/scm-utils.c (stdint.h): Likewise. * i386-linux-tdep.c (stdint.h): Likewise. * i386-tdep.c (stdint.h): Likewise. * nat/linux-btrace.c (stdint.h): Likewise. * nat/linux-btrace.h (stdint.h): Likewise. * nat/linux-ptrace.c (stdint.h): Likewise. * nat/mips-linux-watch.h (stdint.h): Likewise. * ppc-linux-nat.c (stdint.h): Likewise. * python/python-internal.h (stdint.h): Likewise. * stub-termcap.c (stdlib.h): Likewise. * target/target.h (stdint.h): Likewise. * xtensa-linux-nat.c (stdint.h): Likewise. gdb/gdbserver/ChangeLog: * linux-i386-ipa.c (stdint.h): Do not include. * lynx-i386-low.c (stdint.h): Likewise. * lynx-ppc-low.c (stdint.h): Likewise. * mem-break.c (stdint.h): Likewise. * thread-db.c (stdint.h): Likewise. * tracepoint.c (stdint.h): Likewise. * win32-low.c (stdint.h): Likewise.
* Fallback to stub-termcap.c on all hostsPedro Alves2015-04-061-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently building gdb is impossible without an installed termcap or curses library. But, GDB already has a very minimal termcap in the tree to handle this situation for Windows -- gdb/stub-termcap.c. This patch makes that the fallback for all hosts. Testing this on GNU/Linux (by simply hacking away the termcap/curses detection in gdb/configure.ac), we trip on: ../readline/libreadline.a(terminal.o): In function `_rl_init_terminal_io': /home/pedro/gdb/mygit/src/readline/terminal.c:527: undefined reference to `PC' /home/pedro/gdb/mygit/src/readline/terminal.c:528: undefined reference to `BC' /home/pedro/gdb/mygit/src/readline/terminal.c:529: undefined reference to `UP' /home/pedro/gdb/mygit/src/readline/terminal.c:538: undefined reference to `PC' /home/pedro/gdb/mygit/src/readline/terminal.c:539: undefined reference to `BC' /home/pedro/gdb/mygit/src/readline/terminal.c:540: undefined reference to `UP' These are globals that are normally defined by termcap (or ncurses' termcap emulation). Now, we could just define replacements in stub-termcap.c, but readline/terminal.c (at least the copy in our tree) has this: #if !defined (__linux__) && !defined (NCURSES_VERSION) # if defined (__EMX__) || defined (NEED_EXTERN_PC) extern # endif /* __EMX__ || NEED_EXTERN_PC */ char PC, *BC, *UP; #endif /* !__linux__ && !NCURSES_VERSION */ which can result in readline defining the globals too. That will usually work out in C, given that "-fcommon" is usually the default for C compilers, but that won't work for C++, or C with -fno-common (link fails with "multiple definition" errors)... Mirroring those #ifdef conditions in the stub termcap screams "brittle" to me -- I can see them changing in latter readline versions. Work around that by simply using __attribute__((weak)). Windows/PE/COFF's do support weak, but not on gcc 3.4 based toolchains (4.8.x does work). Given the file never needed the variables while it was Windows-only, just continue not defining them there. All other supported hosts should support this. gdb/ChangeLog: 2015-04-06 Pedro Alves <palves@redhat.com> Bernd Edlinger <bernd.edlinger@hotmail.de> * configure.ac: Remove the mingw32-specific stub-termcap.o fallback, and instead fallback to the stub termcap on all hosts. * configure: Regenerate. * stub-termcap.c [!__MINGW32__] (PC, BC, UP): Define as weak symbols.
