/* Generate the assembly code for function entry. FILE is a stdio
stream to output the code to. SIZE is an int: how many units of
temporary storage to allocate.
Refer to the array `regs_ever_live' to determine which registers to
save; `regs_ever_live[I]' is nonzero if register number I is ever
used in the function. This function is responsible for knowing
which registers should not be saved even if used.
We override it here to allow for the new profiling code to go before
the prologue and the old mcount code to go after the prologue (and
after %ebx has been set up for ELF shared library support). */
