From: Zong Li <zongbox@gmail.com> Similar to the recent fix for MIPS, ARM and S/390, RV32 is missing correct exception on overflow from llrint and llround functions because cast from floating-point types to long long do not result in correct exceptions on overflow. 2018-11-29 Zong Li <zong@andestech.com> * sysdeps/riscv/rv32/fix-fp-int-convert-overflow.h: New file. --- ChangeLog | 10 +++++ .../riscv/rv32/fix-fp-int-convert-overflow.h | 38 +++++++++++++++++++ 2 files changed, 48 insertions(+) create mode 100644 sysdeps/riscv/rv32/fix-fp-int-convert-overflow.h
