Are you saying that the C++ standard shouldn't accommodate
microcontrollers, or that the C++ standard shouldn't accommodate
micro-optimisation?
Last Thursday I was at a C++ talk in Belfast by Jason McGuiness where
he was talking about writing template state machines to take advantage
of the x86 instruction:
call qword pointer [ immediate + immediate * register ]
instead of using an 'if else' ladder. He was trying to shave off CPU
cycles in his code for low latency financial trading systems. People
are actually doing that.
