So I rewrote the code using weak | references. If the user has at least GLIBC 2.32, it will use the IEEE 128-bit | string support in the library. | | If an older GLIBC is used, I then use the IBM 128-bit format as an intermediate | value. Obviously there are cases where IEEE 128-bit can hold values that IBM | 128-bit can't (mostly due to the increased exponent range in IEEE 128-bit), but | it at least does the conversion for the numbers in the common range. | | In doing this transformation, I needed to do minor edits to the main decimal | to/from binary conversion functions to allow the KF functions to be declared. | Previously, I used preprocessor magic to rename the functions. This is the second most important patch in the IEEE 128-bit work. What do I need to do to be able to commit the patch? -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meissner@linux.ibm.com, phone: +1 (978) 899-4797
