X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=679cc5075b7bf047ffcb20154cf000e50e15cb38;p=llvm

[mips] Recognise the triple used by Debian for MIPS n32 ABI

Triples like mips64-linux-gnuabin32 are documented in this article:
https://wiki.debian.org/Multiarch/Tuples

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@313231 91177308-0d34-0410-b5e6-96231b3b80d8
