- does not realize that the statement val = find_pc_line (...) will
- change the values of the fields of val. It extracts the elements
- into registers at the top of the block, and does not update the
- registers after the call to find_pc_line. You can check this by
- inserting a printf at the end of find_pc_line to show what values
- it is returning for val.pc and val.end and another printf after
- the call to see what values the function actually got (remember,
- this is compiling with cc -O, with this patch removed). You can
- also examine the assembly listing: search for the second call to
- skip_prologue; the LDO statement before the next call to
- find_pc_line loads the address of the structure which
- find_pc_line will return; if there is a LDW just before the LDO,
- which fetches an element of the structure, then the compiler
- still has the bug.
