1e98f88776 Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into
__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'.

6fda52ba75 Implement fdopendir(3) by splitting __opendir2() into two parts, the upper part
deals with the usual __opendir2() calls, and the rest part with an interface
translator to expose fdopendir(3) functionality.  Manual page was obtained from
kib@'s work for *at(2) system calls.

e058c00c40 Updates for changes in the way printf() handles hex floating point
numbers.
2008-04-12 03:11:56 +00:00

76303a9735 Make several changes to the way printf handles hex floating point (%a):
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.

92a1a6e169 Fix some corner cases:
- fma(x, y, z) returns z, not NaN, if z is infinite, x and y are finite,
  x*y overflows, and x*y and z have opposite signs.
- fma(x, y, z) doesn't generate an overflow, underflow, or inexact exception
  if z is NaN or infinite, as per IEEE 754R.
- If the rounding mode is set to FE_DOWNWARD, fma(1.0, 0.0, -0.0) is -0.0,
  not +0.0.
