C is a reasonably standard procedural language; but it has all the trimmings
needed to generate all the arithmetic and logical operations easily, and
is pretty "close to the metal" in the logic. 

A loop could be

  for (i=0;i<100;i++) foo[i] = i*i;

to make an array foo contain the square of the index in each element.

This would be compiled to some pretty easily mapped intermediate representation, and then
the ~100 optimisation techniques in the normal compiler would be applied to this code, 
sometimes resulting in the eventually emitted assembler would be pretty far removed
from the original code. And sometimes not.

-O0 -g3 -ggdb is the incarnation if you would like to turn the optimisation off, 
emit all the debug information and hooks to the debugger,

-O6 -g0 or -Os -g0 would be max optimised for speed or size and no debug output.

Not that I know of, nor that I care much. This is where C isolate you from the metal.

I invoke 

 result = sqrt(argument) ; 

and let the compiler, linker, loader and libraries sort it out.

-- mrr

Who use arm a lot more than x86, but who is sometimes confused about what architecture
i am actually running on, even when compiling.
