#
# SYNOPSIS
#
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
#
# DESCRIPTION
#
# Check for the presence of an --enable-debug option to configure, with
# the specified default value used when the option is not present. Return
# the value in the variable $ax_enable_debug.
#
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
# languages. Specifying 'info' adds '-g' to the compilation flags.
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
# the linking flags. Otherwise, nothing is added.
#
# Define the variables listed in the second argument if debug is enabled,
# defaulting to no variables. Defines the variables listed in the third
# argument if debug is disabled, defaulting to NDEBUG. All lists of
# variables should be space-separated.
#
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
# Should be invoked prior to any AC_PROG_* compiler checks.
#
# IS-RELEASE can be used to change the default to 'no' when making a
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
# macro, there is no need to pass this parameter.

# SYNOPSIS
#
# AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
#
# DESCRIPTION
#
# This macro compares two version strings. Due to the various number of
# minor-version numbers that can exist, and the fact that string
# comparisons are not compatible with numeric comparisons, this is not
# necessarily trivial to do in a autoconf script. This macro makes doing
# these comparisons easy.
#
# The six basic comparisons are available, as well as checking equality
# limited to a certain number of minor-version levels.
#
# The operator OP determines what type of comparison to do, and can be one
# of:
#
# eq - equal (test A == B)
# ne - not equal (test A != B)
# le - less than or equal (test A <= B)
# ge - greater than or equal (test A >= B)
# lt - less than (test A < B)
# gt - greater than (test A > B)
#
# Additionally, the eq and ne operator can have a number after it to limit
# the test to that number of minor versions.
#
# eq0 - equal up to the length of the shorter version
# ne0 - not equal up to the length of the shorter version
# eqN - equal up to N sub-version levels
# neN - not equal up to N sub-version levels
#
# When the condition is true, shell commands ACTION-IF-TRUE are run,
# otherwise shell commands ACTION-IF-FALSE are run. The environment
# variable 'ax_compare_version' is always set to either 'true' or 'false'
# as well.
#
# Examples:
#
# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
# AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
#
# would both be true.
#
# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
# AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
#
# would both be false.
#
# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
#
# would be true because it is only comparing two minor versions.
#
# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
#
# would be true because it is only comparing the lesser number of minor
# versions of the two values.
#
# Note: The characters that separate the version numbers do not matter. An
# empty string is the same as version 0. OP is evaluated by autoconf, not
# configure, so must be a string, not a variable.
#
# The author would like to acknowledge Guido Draheim whose advice about
# the m4_case and m4_ifvaln functions make this macro only include the
# portions necessary to perform the specific comparison specified by the
# OP argument in the final configure script.

# DESCRIPTION
#
# This macro retrieves the compiler version and returns it in the cache
# variable $ax_cv_c_compiler_version for C and $ax_cv_cxx_compiler_version
# for C++.
#
# Version is returned as epoch:major.minor.patchversion
#
# Epoch is used in order to have an increasing version number in case of
# marketing change.
#
# Epoch use: * borland compiler use chronologically 0turboc for turboc
# era,
#
# 1borlanc BORLANC++ before 5, 2cppbuilder for cppbuilder era,
# 3borlancpp for return of BORLANC++ (after version 5.5),
# 4cppbuilder for cppbuilder with year version,
# and 5xe for XE era.
#
# An empty string is returned otherwise.

# SYNOPSIS
#
# AX_GCC_X86_AVX_XGETBV
#
# DESCRIPTION
#
# On later x86 processors with AVX SIMD support, with gcc or a compiler
# that has a compatible syntax for inline assembly instructions, run a
# small program that executes the xgetbv instruction with input OP. This
# can be used to detect if the OS supports AVX instruction usage.
#
# On output, the values of the eax and edx registers are stored as
# hexadecimal strings as "eax:edx" in the cache variable
# ax_cv_gcc_x86_avx_xgetbv.
#
# If the xgetbv 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_avx_xgetbv_OP is set to the string "unknown".
#
# This macro mainly exists to be used in AX_EXT.
