What fast low-level languages can you recommend?

I have become interested in C-like languages for performance computing. Can you recommend some alternative programming languages which have the following attributes:

  • must be close to the hardware (bit fiddling, pointers or some alternative safe method like references)
  • no managed code (no jvm/.net languages)
  • has to be really fast (like C)
  • must be above ASM level (and yes I am interested in macro languages on top of ASM)
  • can be obscure, not very widespread

I am mainly interested in little-known languages.

Solution

  • How about Assembly language, or the D programming language?
