Author: lenary Date: Tue Sep 3 01:47:58 2019 New Revision: 370709 URL: http://llvm.org/viewvc/llvm-project?rev=370709&view=rev Log: [RISCV] Correct Logic around ilp32e macros
Summary: GCC seperates the `__riscv_float_abi_*` macros and the `__riscv_abi_rve` macro. If the chosen abi is ilp32e, `gcc -march=rv32i -mabi=ilp32i -E -dM` shows that both `__riscv_float_abi_soft` and `__riscv_abi_rve` are set. This patch corrects the compiler logic around these defines. At the moment, this patch will not change clang's behaviour, because we do not accept the `ilp32e` abi yet.
