* gdb.texinfo (Darwin): Document Darwin specific features.
(value_free): Remove macro, make it a function.
* value.c (value): Move actual content outside of the memory space
of the struct; add a pointer to this actual content.
(allocate_value_lazy, allocate_value_contents): New function.
(allocate_value): Reimplement using these two new functions.
(value_contents_raw, value_contents_all_raw): If no memory
has been allocated yet for the actual content, allocate it.
(value_contents_all): Resync with struct value's changes.
(value_free): New function.
(value_copy, value_primitive_field): Use new function
allocate_value_lazy to allocate lazy values.
(value_change_enclosing_type): Resync with struct value's changes.
As the value is not reallocated, remove the special handling for
the value chain (now obsolete).
* valops.c (value_at_lazy): Use new function allocate_value_lazy.
(value_fetch_lazy): Allocate value content. Use allocate_value_lazy
to allocate lazy values.
(value_slice): Use allocate_value_lazy to allocate lazy values.
* ia64-tdep.c: New #if check on BREAKPOINT_MAX vs. BUNDLE_LEN.
(ia64_memory_insert_breakpoint): New comment part for SHADOW_CONTENTS
content. Remove variable instr. New variable cleanup. Force
automatic breakpoints restoration. PLACED_SIZE and SHADOW_LEN are now
set larger, to BUNDLE_LEN - 2. Variable `bundle' type update. Return
error if even just final target_write_memory has failed.
(ia64_memory_remove_breakpoint): Rename variables bundle to bundle_mem
and instr to instr_saved. New variables bundle_saved and
instr_breakpoint. Comment new reasons why we need to disable automatic
restoration of breakpoints. Assert PLACED_SIZE and SHADOW_LEN. New
check of the original memory content. Return error if even just final
target_write_memory has failed.
(ia64_breakpoint_from_pc): Implement the emulation of permanent
breakpoints compatible with current bp_loc_is_permanent.
(template_encoding_table): Make it `const'.
* breakpoint.c (bp_loc_is_permanent): Support unsupported software
breakpoints. New variables `cleanup' and `retval'.
* monitor.c (monitor_insert_breakpoint): Remove unused variable `bp'.
