Level 10: Rearrange Code; Level 11: Reuse of Common Exit Code. Does anyone have any experience of these higher optimisation levels, relying on the LX51 Linker? This thread reported some bugs, and expressed some misgivings about the advantages: http://www.keil.com/forum/docs/thread2094.asp That was v7.02; now we're at v7.07a: Can anyone confirm that the bugs are really fixed now? Does it do any better now? Any other plaudits, Gotchas! or concerns?
"a small gain in increasing the Optimisation level from 9 to 10" About 0.25%, in fact. Hardly worth it really. Stefan
"About 0.25%, in fact. Hardly worth it really." Unless, of course, it was just that last ~150 bytes that was keeping you from fitting the code into the ROM!!
