78necessarily to users of other CPUs. Users of other CPUs should obtain
79information about their gcc version requirements from another source.

81The recommended compiler for the kernel is gcc 2.95.x (x >= 3), and it
82should be used when you need absolute stability. You may use gcc 3.0.x
83instead if you wish, although it may cause problems. Later versions of gcc
84have not received much testing for Linux kernel compilation, and there are
85almost certainly bugs (mainly, but not exclusively, in the kernel) that
86will need to be fixed in order to use these compilers. In any case, using
87pgcc instead of plain gcc is just asking for trouble.
88
89The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.
90You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build
91the kernel correctly.
92
93In addition, please pay attention to compiler optimization. Anything
94greater than -O2 may not be wise. Similarly, if you choose to use gcc-2.95.x
95or derivatives, be sure not to use -fstrict-aliasing (which, depending on
96your version of gcc 2.95.x, may necessitate using -fno-strict-aliasing).
