* add T_POW (**) operatordatibbaw2014-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed recognition of the operator Added opcode, still doing multiply instead of pow() opcode now always returns int(42) The right answer, but always a float Yanked code from pow() implementation. Should not handle negative long as exponent ourselves Added test cases from pow() Moved precedence higher than '~' Added GMP operator overloading Added ZEND_ASSIGN_POW (**=) operator. Added pow() as a language construct. Adjusted test cases for changed precedence. Reduced pow() to shell function around ZEND_API pow_function() Reduced test case to only contain edge cases Added overloading test case Moved unary minus above T_POW Revert "Added pow() as a language construct." Bad bad bad idea. This reverts commit f60b98cf7a8371233d800a6faa286ddba4432d02. Reverted unary minus behaviour due to previous revert. Convert arrays to int(0) Exponent with array as a base becomes int(0) Rebase against master Fixed tokenizer test case

| | | | | | The 'result' argument of fast_add_function() may alias with either of its operands (or both). Take care not to write to 'result' before reading op1 and op2.

* | Fix #64780 (PHP 5.5 builds are broken with GCC 3)Ard Biesheuvel2013-05-071-1/+5
| | | | | | | | | | | | | | | | | | A recent change (by me) introduced a call to __builtin_offsetof() into zend_operators.h which is not defined by GCC prior to version 4. Changed the code to use offsetof() instead: this is defined in <stddef.h>, so #include this header conditionally (#ifdef GNUC)
* | Fix rounding of zend_dval_to_lvalGustavo Lopes2013-02-231-1/+5
| | | | | | | | | | | | Now rounding is always towards zero; the rounding can be though as if occurring on the original double. Only relevant for the 32-bit long variant.
* | Fix zend_dval_to_lval outside 64bit integers rangeGustavo Lopes2013-02-231-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PHP should preserve the least significant bits when casting from double to long. Zend.m4 contains this: AC_DEFINE([ZEND_DVAL_TO_LVAL_CAST_OK], 1, [Define if double cast to long preserves least significant bits]) If ZEND_DVAL_TO_LVAL_CAST_OK is not defined, zend_operators.h had an inline implementation of zend_dval_to_lval() that would do a cast to an int64_t (when sizeof(long) == 4), then a cast to unsigned long and finally the cast to long. While this works well for doubles inside the range of values of the type used in the first cast (int64_t in the 32-bit version and unsigned long in the 64-bit version), if outside the range, it is undefined behavior that WILL give varying and not particularly useful results. This commit uses fmod() to first put the double in a range that can safely be cast to unsigned long and then casts this unsigned long to long. This last cast is implementation defined, but it's very likely that this gives the expected result (i.e. the internal 2's complement representation is unchanged) on all platforms that PHP supports. In any case, the previous implementationa already had this assumption. This alternative code path is indeed significantly slower than simply casting the double (almost an order of magnitude), but that should not matter because casting doubles with a very high absolute value is a rare event.
* | Improve x86 inline assemblerArd Biesheuvel2013-02-111-32/+60
| | | | | | | | | | | | | | - added cc annotation to inline asm that clobbers the condition flags - remove hardcoded constants (IS_LONG,IS_DOUBLE) - remove hardcoded offsets (zval->value, zval->type)
