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

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

| # This macro sets OPENSSL_INCLUDES such that source files should use the | |
