Looks to me like you are describing the C language. From the wikipedia
[C] was designed to be compiled using a relatively
straightforward compiler, to provide low-level access to
memory, to provide language constructs that map efficiently to
machine instructions, and to require minimal run-time support.
C was therefore useful for many applications that had formerly
been coded in assembly language, such as in system programming.
Despite its low-level capabilities, the language was designed to
encourage cross-platform programming. A standards-compliant and
portably written C program can be compiled for a very wide
variety of computer platforms and operating systems with few
changes to its source code.
