* parse.y (valid_builtin_assignconv_identity_widening_p): Got rid
of an ancient workaround.
From-SVN: r25238
* jump.c: Include insn-attr.h.
(delete_computation): If reload has completed and insn scheduling
after reload is enabled, then do not depend on REG_DEAD notes.
* Makefile.in (jump.o): Depend on insn-attr.h.

* toplev.c (documented_lang_options): Remove -fident and
-fnoident, which are now handled by the language independent
option parser.

* c-common.c (UNGETC [USE_CPPLIB=1]): Do nothing if c is EOF.
* c-lex.c: Likewise.
* cpplib.c (cpp_push_buffer, cpp_pop_buffer): Use a linked
list in malloced memory for the buffer stack.
(cpp_get_token): Don't pop the last buffer off the stack.
Calls after CPP_EOF has been returned produce CPP_EOF with no
state change.
(cpp_finish): Pop last buffer here.
(do_line): Don't free ip->last_nominal_fname if it is equal to
ip->fname.
(special_symbol): If a T_CONST is the empty string, push a
single `@ ' escape instead.
(macroexpand): Special symbol buffers have escapes too.
* cpplib.h (struct cpp_buffer): Remove unused fields, add prev
buffer pointer.
(struct cpp_reader): Remove buffer_stack. Add
buffer_stack_depth.
(CPP_PREV_BUFFER, CPP_NULL_BUFFER): Buffer stack is now a
linked list.
From-SVN: r25218
* cccp.c: Don't define HOST_WIDE_INT. Replace all occurrences of
WIDE_INT with WIDEST_INT.
* cexp.y: Likewise.
Don't define unsigned_HOST_WIDE_INT, CHAR_BIT or
HOST_BITS_PER_WIDE_INT. Replace occurrences of PRINTF_PROTO_1()
style with PVPROTO() ATTRIBUTE_PRINTF_1 style macros. Replace
occurrences of "unsigned_HOST" with "unsigned HOST". Provide a
definition of variable `c89' when compiling a test binary and set it.
* system.h: Don't define the PRINTF_PROTO_* macros.

* loop.c (mark_loop_jump): Handle LO_SUM. If we encounter something
we do not understand, mark the loop and containing loops as invalid.

* loop.c (mark_loop_jump): Handle LO_SUM. If we encounter something
we do not understand, mark the loop and containing loops as invalid.
From-SVN: r25214
* loop.c (combine_givs_used_by_other): Delete.
(combine_givs_benefit_from): Delete.
(combine_givs): Deny combination of givs only used once. Simplify
code with the death of combine_givs_benefit_from.
From-SVN: r25183
* arm.md: Use gen_rtx_FOO instead of gen_rtx (FOO, ...).
* arm.h: Likewise.
* arm.c: Likewise.
* arm.h (TARGET_OPTIONS): Reformat for clarity.
(GO_IF_LEGITIMATE_ADDRESS): When generating PIC, references to symbols
in the constant pool aren't valid.
(LEGITIMATE_PIC_OPERAND_P): Likewise.
* arm.c: Include "system.h", not stdio.h and string.h.
From-SVN: r25175
* reload.c (find_reloads_subreg_address): New function, broken out of
find_reloads_toplev.
(find_reloads_toplev, find_reloads_address_1): Use it.
From-SVN: r25169
* config/c4x/c4x.c (c4x_address_cost): Revert 9 Feb change.
(While this patch fixed GIV combination for complex arithmetic
it screwed up generation of autoincrement addresses for the common cases.)
