rlwinm instruction.

mnemonics.

cpplib.c (special_symbol): Rewrite.
1999-02-08 23:25 -0500 Zack Weinberg <zack@midnite.ec.rhno.columbia.edu>
* cpplib.c (special_symbol): Rewrite. Don't copy things
multiple times. Handle __STDC__ specially. T_CONST
indicates a constant /string/. Don't handle T_*_TYPE and
T_SPEC_DEFINED. Use cpp_buf_line_and_col instead of
adjust_position. Determine the file buffer only if needed.
(initialize_builtins): Handle __SIZE_TYPE__,
__PTRDIFF_TYPE__, __WCHAR_TYPE__, __USER_LABEL_PREFIX__, and
__REGISTER_PREFIX__ with T_CONST special hashtab entries.
Don't provide __OBJC__; the driver does that. Provide
__STDC_VERSION__, using T_CONST. Use T_STDC for
__STDC__. Give install the length of all symbols defined.
(eval_if_expression): Drop code to insert and remove the
"defined" special symbol.
* cpplib.h: Remove SELF_DIR_DUMMY (no longer used). Remove
T_*_TYPE and T_SPEC_DEFINED from enum node_type; add T_STDC.
* cpphash.c (install): Drop the `ivalue' parameter. Constify
the `value' parameter. All callers changed.
* cpphash.h (install): Change prototype to match.
(union hashval): Remove `ival' member.
* cppexp.c (cpp_lex): Handle `defined' here.
c-typeck.c (check_init_type_bitfields): Use nonincremental initialization of unions whose first member is a bitfield.

Remove unnecessary code for checking the declaration mode
after DECL_C_BIT_FIELD.
* varasm.c (output_constructor): Additional comment about the
constructor of bitfield union initialization.

* parse.y: DECL_P replaced by JDECL_P.
(build_array_from_name): Always use pointer's type.
(patch_bc_statement): Extra code to search continue target in a
for loop. Fixed comments. Continue target is current loop when
unlabeled.
Fri Jan 29 18:19:02 1999 Alexandre Petit-Bianco <apbianco@cygnus.com>
* lex.c (java_read_char): Fixed utf8 decoding.
(java_unicode_2_utf8): Fixed utf8 encoding in the 0x800-0xffff
range.
* parse.y (valid_builtin_assignconv_identity_widening_p): Fixed
comments. Local variable `all_primitive' is gone. Broadened
acceptance of `0' to floating point targets. `long' can now be
widened to `double' or `float'.
(valid_method_invocation_conversion_p): Added leading
comment. Fixed tabulation.
(build_string_concatenation): Optimize out left or right empty
string constants.

the FPA, emit code for version 3.
When optimizing for space, don't synthesize constants.
Reword several flags based on the requested processor and optimization
level.
(use_return_insn): New argument iscond, all callers changed. Don't
use a return insn if it will be conditional and that would be
expensive; eg on StrongARM.
(arm_adjust_cost): Anti- and output- dependencies normally have no
cost.
(load_multiple_sequence): Newer ARMs don't benefit from ldm if
the sequence is short.
(final_prescan_insn): Use max_insns_skipped instead of
MAX_INSNS_SKIPPED. Note whether we will make a return instruction
