* | Turn 64-bit integer division and modulus by constants into multiply-high | Xavier Leroy | 2016-10-04 | 3 | -0/+124 |
| | | | | | | This trick was already implemented for 32-bit integer division and modulus. Here we extend it to the 64-bit case. For 32-bit target processors, the runtime library must implement 64-bit multiply-high (signed and unsigned). Tentative implementations are provided for IA32 and PowerPC, but need testing. | ||||
* | C reference implementation of the int64 helper functions. | Xavier Leroy | 2015-02-14 | 15 | -0/+905 |
In test_int64.c: don't test FP->int64 conversions when the FP argument is out of range. |
