GNU Compiler Collection - Wikipedia, the free encyclopedia (1137 words) |
 | GCC was originally written by Richard Stallman in 1987 as the compiler for the GNU Project, in order to have a compiler available that was free software. |
| GCC developers have given this part of the compiler the somewhat contradictory name the "middle end." These optimizations include dead code elimination, partial redundancy elimination, global value numbering, sparse conditional constant propagation, and scalar replacement of aggregates. |
| The behavior of the GCC back end is partly specified by preprocessor macros and functions specific to a target architecture, for instance to define the endianness, word size, and calling conventions. |
