The byte order is still little endian 130 * but the word order is big endian. 131 */ 132 #define IEEE_BIG_ENDIAN 133 #endif and result with errors later on: 238 #if defined(IEEE_LITTLE_ENDIAN) + defined(IEEE_BIG_ENDIAN) + defined(VAX) + \ 239 defined(IBM) != 1 240 Exactly one of IEEE_LITTLE_ENDIAN IEEE_BIG_ENDIAN, VAX, or 241 IBM should be defined. 242 #endif 1. such invalid state should be reported using #warning,#error directives. Writing it this way gives ugly errors: /root/php5-5.1.2.debpkg/Zend/zend_strtod.c:240: error: syntax error before "one" /root/php5-5.1.2.debpkg/Zend/zend_strtod.c:241: error: syntax error before "IBM" /root/php5-5.1.2.debpkg/Zend/zend_strtod.c:247: error: syntax error before '}' token /root/php5-5.1.2.debpkg/Zend/zend_strtod.c:247: warning: data definition has no type or storage class /root/php5-5.1.2.debpkg/Zend/zend_strtod.c: In function `ulp': /root/php5-5.1.2.debpkg/Zend/zend_strtod.c:935: error: syntax error before "x" ... 2. commenting out offending section with #warning compilation went without errors. make test had some failures, but their relation to this is uncertain. 3. as i've looked through the code, I've noticed that although both IEEE_BIG_ENDIAN IEEE_LITTLE_ENDIAN are defined, #if defined(LITTLE_ENDIAN) ... #else ... #endif are used for decisions. Under the light of these observations I find lines 126-133 useless on little endian arms without __VFP_FP__ as they only break compilation. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37062&edit=1
