gdb: resume ongoing step after handling fork or vfork

[deliverable/binutils-gdb.git] / gdbserver / acinclude.m4

dnl NB: When possible, try to avoid explicit includes of ../config/ files.
dnl They're normally found by aclocal automatically and recorded in aclocal.m4.
dnl However, some are kept here explicitly to silence harmless warnings from
dnl aclocal when it finds AM_xxx macros via local search paths instead of
dnl system search paths.

dnl gdb/gdbserver/configure.in uses BFD_HAVE_SYS_PROCFS_TYPE.
m4_include(../bfd/bfd.m4)

dnl This gets AM_GDB_WARNINGS.
m4_include(../gdbsupport/warning.m4)

dnl codeset.m4 is needed for common.m4, but not for
dnl anything else in gdbserver.
m4_include(../config/codeset.m4)
m4_include(../gdbsupport/common.m4)

dnl For libiberty_INIT.
m4_include(../gdb/libiberty.m4)

dnl For GDB_AC_PTRACE.
m4_include(../gdbsupport/ptrace.m4)

m4_include(../gdb/ax_cxx_compile_stdcxx.m4)

dnl For GDB_AC_SELFTEST.
m4_include(../gdbsupport/selftest.m4)

dnl Check for existence of a type $1 in libthread_db.h
dnl Based on BFD_HAVE_SYS_PROCFS_TYPE in bfd/bfd.m4.
