* Next stage of stdio cleanup: Retire __sFILEX and merge the fields back intoJohn Baldwin2008-04-1726-143/+72
| | | | | | | | | | | | | | | | | | | | | | __sFILE. This was supposed to be done in 6.0. Some notes: - Where possible I restored the various lines to their pre-__sFILEX state. - Retire INITEXTRA() and just initialize the wchar bits (orientation and mbstate) explicitly instead. The various places that used INITEXTRA didn't need the locking fields or _up initialized. (Some places needed _up to exist and not be off the end of a NULL or garbage pointer, but they didn't require it to be initialized to a specific value.) - For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to avoid namespace pollution of including all the pthread types in stdio.h. Once we remove all the inlines and make __sFILE private it can go back to using pthread_t, etc. - This does not remove any of the inlines currently and does not change any of the public ABI of 'FILE'.

* Make several changes to the way printf handles hex floating point (%a):David Schultz2008-04-123-207/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Previously, printing the number 1.0 could produce 0x1p+0, 0x2p-1, 0x4p-2, or 0x8p-3, depending on what happened to be convenient. This meant that printing a value as a double and printing the same value as a long double could produce different (but equivalent) results. The change is to always make the leading digit a 1, unless the number is 0. This solves the aforementioned problem and has several other advantages. 2. Use the FPU to do rounding. This is far simpler and more portable than manipulating the bits, and it fixes an obsure round-to-even bug. It also raises the exceptions now required by IEEE 754R. The drawbacks are that it is usually slightly slower, and it makes printf less effective as a debugging tool when the FPU is hosed (e.g., due to a buggy softfloat implementation). 3. On i386, twiddle the rounding precision so that (2) works properly for long doubles. 4. Make several simplifications that are now possible due to (2). 5. Split __hldtoa() into a separate file.
