2021-08-26rs6000: inline ldouble __gcc_qsubDavid Edelsohn1-4/+10
While performing some tests of IEEE 128 float for PPC64LE, Michael Meissner noticed that __gcc_qsub is substantially slower than __gcc_qadd. __gcc_qsub calls __gcc_add with the second operand negated. Because the functions normally are invoked through libgcc shared object, the extra PLT overhead has a large impact on the overall time of the function. This patch converts __gcc_qadd to a static inline function invoked by __gcc_qadd and __gcc_qsub. libgcc/ChangeLog: * config/rs6000/ibm-ldouble.c (ldouble_qadd_internal): Rename from __gcc_qadd. (__gcc_qadd): Call ldouble_qadd_internal. (__gcc_qsub): Call ldouble_qadd_internal with second long double argument negated.
