Tool/software: TI C/C++ Compiler
Hi
I'll try to find out whats the difference in some implementations of code - especially the run time.
And my question is what are the comments in the generated assembly files.
LDR A3, [V3, #4] ; [DPU_V7M3_PIPE] |368|
What means the number and why is it jumping around?
Could I see there how long an execution of the code needs out of that?
Kind regards
René
For example in this example out of my code
LDR A3, [V3, #4] ; [DPU_V7M3_PIPE] |368|
