This patch fixes an non-fatal issue about negative constant values derived from FP constant synthesis on hosts whose 'long' is wider than 'int32_t'. And also replaces the dedicated code in FP constant synthesis split pattern with the appropriate existing function call. gcc/ChangeLog: * config/xtensa/xtensa.md: In FP constant synthesis split pattern, subcontract to avoid_constant_pool_reference() as in the case of integer, because it can handle well too. And cast to int32_t before calling xtensa_constantsynth() in order to ignore upper 32-bit. gcc/testsuite/ChangeLog: * gcc.target/xtensa/constsynth_double.c: Modify in order to catch the issue.
