The latest version(2019.2) of Arm Mobile Studio's Arm Offline Compiler doesn't output information "Instructions Emitted", but "Total Instruction Cycles"
Where can I download the history release builds of Arm Mobile Studio? At least I got the "Instructions Emitted" report last year.
According to official doc,
"Instructions Emitted:
The number of instructions of each type that are present in the shader program. This row gives a sense of the overall size of the program, ignoring any control flow. This row is specific to Midgard GPUs."
So the thread can be closed due to my miss understanding.
Note that in the next release we will be standardizing on "Total Instruction Cycles" for all GPUs, including Midgard. This is simply a performance normalized version of the "Instructions Emitted" data.
