#
# SYNOPSIS
#
# AX_CC_MAXOPT
#
# DESCRIPTION
#
# Try to turn on "good" C optimization flags for various compilers and
# architectures, for some definition of "good". (In our case, good for
# FFTW and hopefully for other scientific codes. Modify as needed.)
#
# The user can override the flags by setting the CFLAGS environment
# variable. The user can also specify --enable-portable-binary in order to
# disable any optimization flags that might result in a binary that only
# runs on the host architecture.
#
# Note also that the flags assume that ANSI C aliasing rules are followed
# by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
# computations can be re-ordered as needed.
#
# Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
# AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

# SYNOPSIS
#
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_CXXFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_FCFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
#
# DESCRIPTION
#
# Try to find a compiler option that enables most reasonable warnings.
#
# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
#
# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
# Intel compilers. For a given compiler, the Fortran flags are much more
# experimental than their C equivalents.
#
# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
# - $2 add-value-if-not-found : nothing
# - $3 action-if-found : add value to shellvariable

dnl implementation tactics:
dnl the for-argument contains a list of options. The first part of
dnl these does only exist to detect the compiler - usually it is
dnl a global option to enable -ansi or -extrawarnings. All other
dnl compilers will fail about it. That was needed since a lot of
dnl compilers will give false positives for some option-syntax
dnl like -Woption or -Xoption as they think of it is a pass-through
dnl to later compile stages or something. The "%" is used as a
dnl delimiter. A non-option comment can be given after "%%" marks
dnl which will be shown but not added to the respective C/CXXFLAGS.

# AX_CONFIGURE_ARGS
#
# DESCRIPTION
#
# Helper macro for AX_ENABLE_BUILDDIR.
#
# The traditional way of starting a subdir-configure is running the script
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
# to rely on eval'ing $ac_configure_args however some old autoconf
# versions do not provide that. To ensure maximum portability of autoconf
# extension macros this helper can be AC_REQUIRE'd so that
# $ac_configure_args will alsways be present.
#
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
# spoiled now and must be replaced by "eval + exit $?".
#
# Example:
#
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
# eval $SHELL $ac_configure_args || exit $?
# ...])

# SYNOPSIS
#
# AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
#
# DESCRIPTION
#
# If the current configure was run within the srcdir then we move all
# configure-files into a subdir and let the configure steps continue
# there. We provide an option --disable-builddir to suppress the move into
# a separate builddir.
#
# Defaults:
#
# $1 = $host (overridden with $HOST)
# $2 = Makefile.mk
# $3 = -all
#
# This macro must be called before AM_INIT_AUTOMAKE. It creates a default
# toplevel srcdir Makefile from the information found in the created
# toplevel builddir Makefile. It just copies the variables and
# rule-targets, each extended with a default rule-execution that recurses
# into the build directory of the current "HOST". You can override the
# auto-dection through `config.guess` and build-time of course, as in
#
# make HOST=i386-mingw-cross
#
# which can of course set at configure time as well using
#
# configure --host=i386-mingw-cross
#
# After the default has been created, additional rules can be appended
# that will not just recurse into the subdirectories and only ever exist
# in the srcdir toplevel makefile - these parts are read from the $2 =
# Makefile.mk file
#
# The automatic rules are usually scanning the toplevel Makefile for lines
# like '#### $host |$builddir' to recognize the place where to recurse
# into. Usually, the last one is the only one used. However, almost all
# targets have an additional "*-all" rule which makes the script to
# recurse into _all_ variants of the current HOST (!!) setting. The "-all"
# suffix can be overriden for the macro as well.
#
# a special rule is only given for things like "dist" that will copy the
# tarball from the builddir to the sourcedir (or $(PUB)) for reason of
# convenience.

# SYNOPSIS
#
# AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
#
# DESCRIPTION
#
# This macro tries to guess the "native" arch corresponding to the target
# architecture for use with gcc's -march=arch or -mtune=arch flags. If
# found, the cache variable $ax_cv_gcc_archflag is set to this flag and
# ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
# "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
# to add $ax_cv_gcc_archflag to the end of $CFLAGS.
#
# PORTABLE? should be either [yes] (default) or [no]. In the former case,
# the flag is set to -mtune (or equivalent) so that the architecture is
# only used for tuning, but the instruction set used is still portable. In
# the latter case, the flag is set to -march (or equivalent) so that
# architecture-specific instructions are enabled.
#
# The user can specify --with-gcc-arch=<arch> in order to override the
# macro's choice of architecture, or --without-gcc-arch to disable this.
#
# When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
# called unless the user specified --with-gcc-arch manually.
#
# Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
#
# (The main emphasis here is on recent CPUs, on the principle that doing
# high-performance computing on old hardware is uncommon.)

# SYNOPSIS
#
# AX_GCC_X86_CPUID(OP)
#
# DESCRIPTION
#
# On Pentium and later x86 processors, with gcc or a compiler that has a
# compatible syntax for inline assembly instructions, run a small program
# that executes the cpuid instruction with input OP. This can be used to
# detect the CPU type.
#
# On output, the values of the eax, ebx, ecx, and edx registers are stored
# as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
# ax_cv_gcc_x86_cpuid_OP.
#
# If the cpuid instruction fails (because you are running a
# cross-compiler, or because you are not using gcc, or because you are on
# a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
# is set to the string "unknown".
#
# This macro mainly exists to be used in AX_GCC_ARCHFLAG.
