Subject: [PATCH] MIPS: recoginze mipsisa64 as 64bit CPU
Date: Tue, 15 Aug 2023 18:48:21 +0800 [thread overview]
Message-ID: <20230815104821.41855-1-yunqiang.su@cipunited.com> (raw)
In GCC, mipsisa64* in triples are recoginzed as 64bit CPU.
Let's do the same.
The default ABI is determined by the abi section of triples,
which is same with the `mips64*' CPU:
-gnuabi64 and -openbsd for N64
otherwise, N32.
