193 * Originally X was an array. As it's automatic it's natural
194 * to expect RISC compiler to accomodate at least part of it in
195 * the register bank, isn't it? Unfortunately not all compilers
196 * "find" this expectation reasonable:-( On order to make such
197 * compilers generate better code I replace X[] with a bunch of
198 * X0, X1, etc. See the function body below...
199 * <appro@fy.chalmers.se>
204 * However! Some compilers (most notably HP C) get overwhelmed by
205 * that many local variables so that we have to have the way to
206 * fall down to the original behavior.
