26 /* See the comment by the definition of LIBGCC2_UNITS_PER_WORD in
27 m32c.h for why we are creating extra versions of some of the
28 functions defined in libgcc2.c.
30 Note - this file is separate from lib2funcs.c so that the following
31 functions will appear in the their object file. This is necessary
32 because they call abort() which is defined in the C library whereas
33 the functions in lib2funcs.c are completely self sufficient. */
