*	Fix static-binary lazy FPU context allocation	Maciej W. Rozycki	2013-09-09	5	-7/+40
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Long ago static startup did not parse the auxiliary vector and therefore could not get at any `AT_FPUCW' tag to check whether upon FPU context allocation the kernel would use a FPU control word setting different to that provided by the `__fpu_control' variable. Static startup therefore always initialized the FPU control word, forcing immediate FPU context allocation even for binaries that otherwise never used the FPU. As from GIT commit f8f900ecb9096ec47f5b7bb7626e29223c69061a static startup supports parsing the auxiliary vector, so now it can avoid explicit initialization of the FPU control word, just as can dynamic startup, in the usual case where the setting written to the FPU control word would be the same as the kernel uses. This defers FPU context allocation until the binary itself actually pokes at the FPU. Note that the `AT_FPUCW' tag is usually absent from the auxiliary vector in which case _FPU_DEFAULT is assumed to be the kernel default.

*	math: Additional type conversion tests	Thomas Schwinge	2013-08-29	1	-7/+13
\| \| \| \| \| \|	These have helped me find and fix type conversion issues in QEMU's MIPS hardware emulation. While certainly glibc is not the best place for such tests, they're just an enhancement of tests already present.

*	BZ #15536: Fix ulp for 128-bit IBM long double.	Carlos O'Donell	2013-06-03	1	-11/+26
\| \| \| \| \| \| \| \|	In 128-bit IBM long double the precision of the type decreases as you approach subnormal numbers, equaling that of a double for subnormal numbers. Therefore adjust the computation in ulp to use 2^(MIN_EXP - MANT_DIG) which is correct for FP_SUBNORMAL for all types.

*	Correctly compute ulp near zero.	Carlos O'Donell	2013-05-24	1	-48/+93
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The current value used for ulp near zero is wrong, and this commit fixes it such that ulp(0) is the smallest subnormal value nearest to zero, which makes the most sense for testing values near zero. Note that this is not what Java does; they use the nearest normal value, which is less accurate than what we want for glibc. Note that there is no correct implementation of ulp since there is no strict mathmatical definition that is accepted by all groups using IEEE 754. Previously with the large ulp values near zero there were tests that previously passed, but were in fact billions of ulp away from the precise answer. With this commit we now need to disable one of the cpow tests which is revealed to be inaccurate (bug 14473). --- 2013-05-24 Carlos O'Donell <carlos@redhat.com> * math/libm-test.inc (MAX_EXP): Define. (ULPDIFF): Define. (ulp): New function. (check_float_internal): Use ULPDIFF. (cpow_test): Disable failing test. (check_ulp): Test ulp() implemetnation. (main): Call check_ulp before starting tests.
