-/* Fix and Continue.
-
- NOTES:
- 1) this facility requires suitable support from a modified version
- of GDB, which is not provided on any system after MacOS 10.7/Darwin11.
- 2) There is no support for this in any X86 version of the FSF compiler.
-
- Fix and continue was used on some earlier MacOS systems for rapid turn
- around debugging. When code is compiled with the -mfix-and-continue
- flag, two changes are made to the generated code that allow the system
- to do things that it would normally not be able to do easily. These
- changes allow gdb to load in recompilation of a translation unit that
- has been changed into a running program and replace existing functions
- and methods of that translation unit with versions of those functions
- and methods from the newly compiled translation unit. The new functions
- access the existing static symbols from the old translation unit, if the
- symbol existed in the unit to be replaced, and from the new translation
- unit, otherwise.
-
- The changes are to insert 5 nops at the beginning of all functions
- and to use indirection to get at static symbols. The 5 nops
- are required by consumers of the generated code. Currently, gdb
- uses this to patch in a jump to the overriding function, this
- allows all uses of the old name to forward to the replacement,
- including existing function pointers and virtual methods. See
- rs6000_emit_prologue for the code that handles the nop insertions.
-
- The added indirection allows gdb to redirect accesses to static
- symbols from the newly loaded translation unit to the existing
- symbol, if any. @code{static} symbols are special and are handled by
- setting the second word in the .non_lazy_symbol_pointer data
- structure to symbol. See indirect_data for the code that handles
- the extra indirection, and machopic_output_indirection and its use
- of MACHO_SYMBOL_FLAG_STATIC for the code that handles @code{static}
- symbol indirection. */
