20 | # | |
21 | # 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. | |

105 | # AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT]) | |
106 | # | |
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. | |
