|
||||
Subject: [PATCH 10/28] Use GCC builtins for ceil functions if desired.
|
||||
|
||||
This patch is using the corresponding GCC builtin for ceilf, ceil,
|
||||
ceill and ceilf128 if the USE_FUNCTION_BUILTIN macros are defined to one
|
||||
in math-use-builtins.h.
|
||||
|
||||
This is the case for s390 if build with at least --march=z196 --mzarch.
|
||||
Otherwise the generic implementation is used. The code of the generic
|
||||
implementation is not changed.
