Questions tagged [gnat]

the GNU Ada compiler that comes as part of GCC (the GNU Compiler Collection including the GNU C Compiler). This tag includes all the various versions of GNAT: • GNAT Community Edition as released by AdaCore under GPL, • FSF as available with gcc distributions under GPL with Runtime Library Exception, and • GNAT Pro under proprietary license from AdaCore.

When under development through a USA Department of Defense contract, GNAT was originally an acronym for The GNU NYU Ada 9X Translator. GNAT is a Ada-language front end in the GNU Compiler Collection (GCC) that adorns the GCC C/C++ GIMPL semantic tree with Ada semantics. This GIMPLE semantic tree is then fed into the Register Transfer Language (RTL) backend of GCC to produce assembly language and/or machine code. Modern GNAT also has an LLVM backend as well.
