Subject: [mips] Enable IAS by default for Android 64-bit MIPS target (N64)
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=703b84157fe3879c4dc8f5c1e5838b4efefdd70f;p=clang

[mips] Enable IAS by default for Android 64-bit MIPS target (N64)

IAS is already used for MIPS64 in majority of Android projects.
Android MIPS64 uses N64 ABI. Set IAS as a default now.
