(fold_rtx): For SUBREG, actually test subreg_lowpart_p in the
code to handle narrowing subregs. And exclude binary ops like DIV
where truncating the args is not valid.
From-SVN: r2160
(load store patterns): Prepend loads and stores with %V
and %v to track the type and address of the access.
(call_movstrsi_loop): Renamed from call_block_move_loop.
Use call-value for the block move patterns.
From-SVN: r2153
(print_operand): Track volatile memory references and output a
serializing instruction before a load when necessary.
(m88k_version, m88k_version_0300): New variables.
From-SVN: r2150
(SIGNED_CHAR_SPEC): Use #if rather than ?: to handle
setting the default SIGNED_CHAR_SPEC macro, since the 3.0 version
of the MIPS C compiler doesn't like ?: in initializers.
From-SVN: r2145
(lang_identifier): Add limbo_value field for out of
scope block level extern declarations.
(IDENTIFIER_LIMBO_VALUE): New define, to access that field.
From-SVN: r2129
(pushdecl): Check an extern decl against both previous global and
previous limbo declarations. For global declarations, clear limbo
value field. For block level extern declarations, set limbo field
if zero.
(grokdeclarator): If this is a block level extern, then allocate
it on the permanent obstack, not the temporary obstack.
From-SVN: r2128
Diagnose duplicate `l' and `u' suffixes. Diagnose ` 0x ' and ` 0a '.
Warn about integer constants that are so large that they are unsigned.
From-SVN: r2121
Replace `(unsigned)' with `(unsigned long)'. When
evaluating << and >>, compute the correct answer without shifting
by more than HOST_BITS_PER_LONG, or by a negative quantity.
(integer_overflow, left_shift, right_shift): New functions.
From-SVN: r2118
Some code come from output_zdepi.
(output_zdepi): Removed. (depi_cint_operand): New name for zdepi_operand.
(consec_zeros_p, and_operand, ior_mask_p, ior_operand,
output_and, output_ior): New functions.
(output_load_address): Removed. Nothing uses it.
From-SVN: r2115
(several patterns): Make sure # of attribute alternatives
match # of constraint alternatives.
Return assembler output template instead of calling output_asm_insn.
Don't write to operands[n] for n >= max operand number in the
pattern, use xoperands instead.
(casesi): Rewrite. Used to be buggy and slow.
(and-not patterns): Make them canonical. Put operands in the right order.
(negsi2): Don't use @ for just one output template.
(movstrsi): Change `!= 4' => `< 4' in test for alignment.
(adddi3): Extend to handle CONST_INT.
(ior-with-immediate optimizer): New pattern.
(and-with-immediate optimizer): New pattern.
(sCC, bCC expanders): Remove constraints.
(high:DI recognizer): Add return \"\".
