(declare_hidden_char_array): New function to
factor out duplicate code in declare_function_name.
Don't set DECL_EXTERNAL (which is illegal without TREE_PUBLIC)
to prevent output; instead, set TREE_ASM_WRITTEN.

(declare_function_name): Use declare_hidden_char_array.

(MAXDECEXP, MINDECEXP): New decimal exponent limits
that vary with definition of LONG_DOUBLE_TYPE_SIZE.
(endian, ereal_atof, real_value_truncate, einfin, emdnorm, asctoeg):
Add cases for TFmode.
(etartdouble): New function converts REAL_VALUE_TYPE to TFmode
for use by ASM_OUTPUT_LONG_DOUBLE.
(edivm, emulm): Ifdef out, replace by faster multiply and divide.
(etoe113, toe113, e113toe): New type conversions for TFmode.
(asctoe113, e113toasc): New TFmode binary <-> decimal conversions.
(at top level): Define constants ezero, eone, emtens, etens, ...
in a new 20-byte format when LONG_DOUBLE_TYPE_SIZE = 128 and
set NE to 10.  Otherwise, the internal format remains 12 bytes wide.
(etoudi, etodi, ditoe, uditoe): New functions, signed and unsigned
DImode float and fix, for real.c used in a libgcc-of-last-resort.
(esqrt): New function, correctly rounded square root for libgcc.
(etodec): Delete ifdef'd version.
(eroundi, eroundui): Rename to efixi, efixui and always
round towards zero.
From frank@atom.ansto.gov.au (Frank Crawford):
(etoibm, toibm, ibmtoe): New conversions for IBM 370 float format.
(e53toe, e64toe, toe64, etoe53, toe53, etoe24, toe24, asctoe53,
asctoeg, make_nan): Ifdef for IBM.

From-SVN: r5153

(REAL_VALUE_TYPE): Define array at least 20 bytes wide
if LONG_DOUBLE_TYPE_SIZE is 128 bits.
(etartdouble): Declare and use for REAL_VALUE_TO_TARGET_LONG_DOUBLE
when long double is TFmode.
(REAL_VALUE_FIX, REAL_VALUE_UNSIGNED_FIX): Must always round
towards zero.

(comparison patterns): Eliminate generation of "sfi."; no such instruction
exists.

(output_init_element): Don't call default_conversion for a STRING_CST if type is directly suitable for it.

(output_init_element): Don't call default_conversion
for a STRING_CST if type is directly suitable for it.
(digest_init): Eliminate a lot of code that checks the variable
'element', since element is always 0 in these code paths.

(build_c_cast): For (void *) (FOO *) 0, return a nop_expr
so it doesn't count as a null pointer constant.
(convert_for_assignment, build_binary_op): Pedantically warn about
that case if looking for a null_pointer_constant.
(build_conditional_expr): Likewise.

(attribute "length"): New attribute; put on all insns that don't have default
length.
(branch patterns): If conditional branch won't reach, take conditional branch
around an unconditional branch.

(plus): Split (plus (COMPARISON FOO ...) ...) at FOO.

Fix all callers.
(emit_move_sequence): Delete 3rd arg SCRATCH_REG.  Fix all
callers.  If operand1 is an invalid PIC address, then legitimize
it before doing anything else.

From-SVN: r5145

(SECONDARY_INPUT_RELOAD_CLASS): Delete case for invalid
PIC addresses.
(CONSTANT_ADDRESS_P): Reject invalid PIC addresses.
(LEGITIMATE_PIC_OPERAND_P): New macro.
(GO_IF_LEGITIMATE_ADDRESS): Reject invalid PIC addresses.
(LEGITIMIZE_ADDRESS): Fix call to legitimize_pic_address.

From-SVN: r5144

(*): Fix all callers of legitimize_pic_address and emit_move_sequence.
