C23 adds various <math.h> function families originally defined in TS 18661-4. Add the atan2pi functions (atan2(y,x)/pi). Tested for x86_64 and x86, and with build-many-glibcs.py.

# The follow CFLAGS are a work around for GCC Bugzilla Bug 29253
|
|
# "expand_abs wrong default code for floating point"
|
|
# As this is not a regression, a fix is not likely to go into
|
|
# gcc-4.1.1 and may be too late for gcc-4.2. So we need these flags
|
|
# until the fix in a gcc release and glibc drops support for earlier
|
|
# versions of gcc.
|
|
#
|
|
# This bug can cause wrong signs of zero results from fabsl, and
|
|
# spurious "invalid" exceptions from comparisons with NaN in the
|
|
# default code sequence generated. The fpclassify expansion used by
|
|
# __builtin_fpclassify, which is used in the absence of
|
|
# -fsignaling-nans, uses __builtin_fabsl, and is not affected by
|
|
# -fno-builtin-fabsl, so requiring -fsignaling-nans for some affected
|
|
# source files.
