cp:
* class.c (dfs_unshared_virtual_bases): Add ATTRIBUTE_UNUSED.
(layout_empty_base): Return at end flag.
(build_base_field): Likewise.
(build_base_fields): Likewise.
(layout_virtual_bases): Don't add 1 to eoc value.
(end_of_class): Use full size for empty bases.
(layout_class_type): Clear CLASSNEARLY_EMPTY_P if we appended
empty bases. Don't add 1 to eoc value. Only add trailing padding
if we're an empty class with no empty bases.
(dump_class_hierarchy): Dump size and alignment.
testsuite:
* g++.old-deja/g++.abi/empty2.C: New test.
* g++.old-deja/g++.abi/empty3.C: New test.
From-SVN: r41460
* search.c (lookup_field_r): If looking for type and non-TYPE_DECL
is found, look first if name does not match the structure name.
* g++.old-deja/g++.other/lookup23.C: New test.
From-SVN: r41447
* fold-const.c (fold): Use first_rtl_op rather than
TREE_CODE_LENGTH when looping over parameters of a tree.
Correct strange grouping in test for evaluated SAVE_EXPR.

name at 32 total characters.
(ASM_OUTPUT_SECTION_NAME): Similarly. Also, only support placing
functions in named sections -- data items can still go into unique
sections, but they have normal names (ie $LIT$ and $DATA$).
* config/pa/som.h (SUPPORTS_INIT_PRIORITY): SOM does not support
INIT_PRIORITY.
From-SVN: r41436
