The defined DEF_EXT_LIB_FLOATN_NX_BUILTINS functions should also
have DEF_INTERNAL_FLT_FLOATN_FN instead of DEF_INTERNAL_FLT_FN for
the FLOATN support. According to the glibc API and gcc builtin, we
have below table for the FLOATN is supported or not.
+---------+-------+-------------------------------------+
| | glibc | gcc: DEF_EXT_LIB_FLOATN_NX_BUILTINS |
+---------+-------+-------------------------------------+
| iceil | N | N |
| ifloor | N | N |
| irint | N | N |
| iround | N | N |
| lceil | N | N |
| lfloor | N | N |
| lrint | Y | Y |
| lround | Y | Y |
| llceil | N | N |
| llfllor | N | N |
| llrint | Y | Y |
| llround | Y | Y |
+---------+-------+-------------------------------------+
This patch would like to support FLOATN for:
1. lrint
2. lround
3. llrint
4. llround
The below tests are passed within this patch:
1. x86 bootstrap and regression test.
2. aarch64 regression test.
3. riscv regression tests.
PR target/112432
gcc/ChangeLog:
* internal-fn.def (LRINT): Add FLOATN support.
(LROUND): Ditto.
(LLRINT): Ditto.
(LLROUND): Ditto.
