# AX_C_FLOAT_WORDS_BIGENDIAN([ACTION-IF-TRUE], [ACTION-IF-FALSE], [ACTION-IF-UNKNOWN])
22
#
23
# DESCRIPTION
24
#
25
# Checks the ordering of words within a multi-word float. This check is
26
# necessary because on some systems (e.g. certain ARM systems), the float
27
# word ordering can be different from the byte ordering. In a multi-word
28
# float context, "big-endian" implies that the word containing the sign
29
# bit is found in the memory location with the lowest address. This
30
# implementation was inspired by the AC_C_BIGENDIAN macro in autoconf.
31
#
32
# The endianness is detected by first compiling C code that contains a
33
# special double float value, then grepping the resulting object file for
34
# certain strings of ASCII values. The double is specially crafted to have
35
# a binary representation that corresponds with a simple string. In this
36
# implementation, the string "noonsees" was selected because the
37
# individual word values ("noon" and "sees") are palindromes, thus making
38
# this test byte-order agnostic. If grep finds the string "noonsees" in
39
# the object file, the target platform stores float words in big-endian
40
# order. If grep finds "seesnoon", float words are in little-endian order.
41
# If neither value is found, the user is instructed to specify the
42
# ordering.

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])

#
107
# DESCRIPTION
108
#
109
# Check whether the given FLAG works with the current language's compiler
110
# or gives an error. (Warnings, however, are ignored)
111
#
112
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
113
# success/failure.
114
#
115
# If EXTRA-FLAGS is defined, it is added to the current language's default
116
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
117
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
118
# force the compiler to issue an error when a bad flag is given.
119
#
120
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
121
#
122
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
123
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.
