Backport changes to fission implementation required by
trunk. See
http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02684.html and
susbsequent messages for a full description of what needed to
change for it to be accepted into trunk. Most of the original
changes were already in google-4_7, so this is just the diff
between the two implementations.
These changes happen to make the resulting debug info smaller, so are
useful to have on this branch.
* dwarf2out.h (addr_table_entry_struct): Forward declare.
(dw_val_struct): Change name and associated type of field val_index
to val_entry.
* dwarf2out.c (NOT_INDEXED, NO_INDEX_ASSIGNED, UNRELOCATED_OFFSET,
RELOCATED_OFFSET): New defines.
(ate_kind): New enum with enumerators ate_kind_rtx,
ate_kind_rtx_dtprel, ate_kind_label.

Change field name from val_index to val_entry, and intialize properly.
(size_of_loc_descr, output_loc_operands): Add assertion and update call.
(set_AT_index): Remove obsolete function.
(remove_addr_table_entry, add_AT_lbl_id,
add_AT_range_list, add_ranges_by_labels): Update prototypes, adjust
all calls in file.
(dtprel_bool): New enum with dtprel_false and dtprel_true.
(dw_addr_op, new_addr_loc_descr): Update functions to use dtprel_bool,
plus additional logic to handle val_entries. Use RELOCATED_OFFSET
and UNRELOCATED_OFFSET.
(AT_index, output_loc_list): Update comment. Update logic to handle
val_entry.
(add_AT_low_high_pc): Update comment. Change field name from
val_index to val_entry, and call add_addr_table entry.
(indirect_string_node, index_string_table): Delete obsolete types,
variables and tables.
(AT_string_form): Move most logic to ...
(find_string_form): ... here and ...
(set_indirect_string): ... here. New function.

dtprel_bool enumerators.
(output_macinfo_op): Fix FIXME by handling DW_FORM_strp's and
DW_FORM_GNU_str_index.

Fixed the problem that LINUX_GRTE_EXTRA_SPECS overrides

SUBTARGET_EXTRA_SPECS.
* gcc/config/i386/gnu-user.h (SUBTARGET_EXTRA_SPECS_STR): Add

* gcc/config/i386/linux.h (SUBTARGET_EXTRA_SPECS): Compute new value
of LINUX_GRTE_EXTRA_SPECS by pre-pending LINUX_GRTE_EXTRA_SPECS to its

Revert old implementation of CPU runtime detection to allow
the new implementation checked in to trunk at rev. 188417 to
be merged.
Revert rev 185093
Backport rev 185083 from google/main
Patch to add builtins to detect CPU type:
========================================
I have ported the patch from google/gcc-4_6 to google/main. I also want this
patch to be considered for trunk. Please see this discussion:
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01355.html
when this patch for reviewed the last time.
One of the main concerns was about making CPU detection initialization a
constructor. The main point raised was about constructor ordering. I have now
added a priority value to the CPU detection constructor to make it very high
priority so that it is guaranteed to fire before every constructor without
an explicitly marked priority value of 101. However, IFUNC initializers
will still fire before this constructor, so the cpu initialization routine
has to be explicitly called in such initializers for which I have added a
builtin: __builtin_cpu_init ().
I would like to reopen discussions on this to make it suitable for trunk
this time around.
This patch adds the following new builtins:
__builtin_cpu_init
__builtin_cpu_supports_cmov
__builtin_cpu_supports_mmx
__builtin_cpu_supports_popcount
__builtin_cpu_supports_sse
__builtin_cpu_supports_sse2
__builtin_cpu_supports_sse3
__builtin_cpu_supports_ssse3
__builtin_cpu_supports_sse4_1
__builtin_cpu_supports_sse4_2
__builtin_cpu_is_amd
__builtin_cpu_is_intel_atom
__builtin_cpu_is_intel_core2
__builtin_cpu_is_intel
__builtin_cpu_is_intel_corei7
__builtin_cpu_is_intel_corei7_nehalem
__builtin_cpu_is_intel_corei7_westmere
__builtin_cpu_is_intel_corei7_sandybridge
__builtin_cpu_is_amdfam10
