I write a TAA shader in unity,I try to optimization this shader,change some float to half.
then I compare the shader brfore and after with mali offline compiler
Mali-G76 before,no spilling
Mali-G77 after,no spilling
1.Why the results of Mali-G76 and Mali-G77 are opposite
2.Why do I reduce the calculation precision, but it spilling on Mali-G76
