; These tests were generated from simplified libm C code.
; When compiled for the x86_64-linux-android target,
; long double is mapped to f128 type that should be passed
; in SSE registers. When the f128 type calling convention
; problem was fixed, old llvm code failed to handle f128 values
; in several f128/i128 type operations. These unit tests hopefully
; will catch regression in any future change in this area.
; To modified or enhance these test cases, please consult libm
; code pattern and compile with -target x86_64-linux-android
; to generate IL. The __float128 keyword if not accepted by
; clang, just define it to "long double".
