URL: http://llvm.org/viewvc/llvm-project?rev=227089&view=rev
Log:
[mips] Enable arithmetic and binary operations for the i128 data type.
Summary:
This patch adds support for some operations that were missing from
128-bit integer types (add/sub/mul/sdiv/udiv... etc.). With these
changes we can support the __int128_t and __uint128_t data types
from C/C++.
Depends on D7125
