Lcc is a new retargetable compiler for ANSI C. Versions for the VAX,
Motorola 68020, SPARC, and MIPS are in production use at Princeton
University and at AT&T Bell Laboratories. With a few exceptions,
little about lcc is unusual -- it integrates several well-engineered,
existing techniques -- but it is smaller and faster than most other C
compilers, and it generates code of comparable quality. Lcc's
target-independent front end performs a few simple, but effective,
optimizations that contribute to good code; examples include simulating
register declarations and partitioning switch statement cases into
dense tables. It also implements target-independent function tracing
and expression-level profiling.
