; 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

|
|

Add LiveRangeShrink pass to shrink live range within BB.
Summary: LiveRangeShrink pass moves instruction right after the definition with the same BB if the instruction and its operands all have more than one use. This pass is inexpensive and guarantees optimal live-range within BB.
