| |
The OPTIMIZE_INLINING help currently says "The gcc 4.x series have a rewritten inlining algorithm and disabling this option will generate a smaller kernel there."
This contradicts other parts of the help text and my own tests: 5463127 2008-10-11 19:51 vmlinux.no-opt 5456152 2008-10-11 19:56 vmlinux.opt
Reword text to say that enabling OPTIMIZE_INLINING will lead to smaller kernels with gcc 4.x or later.
