Hello All:
Here is the patch for Inline lrint and lrintf. Currently glibc don't
use __builtin_lrint as they inline lrint with fctid/fctiw instruction.
With the below changes such inlines are not required and lrint builtin
can be used.
Bootstrapped and regtested on powerpc64-linux-gnu.
rs6000: Inline lrint,lrintf
For hard-float powerpc, GCC should support inline code generation
for the lrint or lrintf built-in functions, subject only to
-fno-math-errno (the condition -fno-math-errno is already checked
in builtins.c:expand_builtin_int_roundingfn_2, so the back end's
lrint insn patterns do not need to check that condition).
TARGET_FPRND has nothing to do with fctid and fctiw.
Remove the TARGET_FPRND from lrint<mode>di2 pattern.

* config/rs6000/rs6000.md (lrint<mode>di2): Remove TARGET_FPRND
condition from pattern.
