#98567 - Source code useless
Responding to: Jan Waclawek's previous message
Jan Waclawek said:
I have not seen any, is it standalone or integrated with the compiler/linker/whatever other tool?

I've seen them separate - dunno about anything specifically for the 8051, though. :-(

My point is, the compiler knows what is the source/it's "fundamental" blocks ...

My point is that this is of no use whatever - what you require can only be done by examining the generated code.

... and the corresponding assembler output so the compiler is the best place where I would expect to such "profiling" should be integrated into.

Actually, that's not quite true - things like Keil's LX51 Linker & the Raisonance CodeCompressor can perform further optimisations after the compiler has finished!
