* Makefile.in (MACHMODE_H): Add @extra_modes_file@.
	* configure.in: If $srcdir/config/${cpu_type}/${cpu_type}-modes.def
	exists, substitute its pathname as @extra_modes_file@, define
	EXTRA_MODES_FILE to be an appropriate string to #include it
	with, and define EXTRA_CC_MODES to 1.

	* machmode.def: Update comments.  Include EXTRA_MODES_FILE if
	it's defined.  Get rid of redundancy in calling sequence for
	CC; don't use it to define CCmode, to avoid a warning.
	* libgcc2.c: Include symcat.h for the sake of machmode.def.

/* Add any extra modes needed to represent the condition code.
On the C4x, we have a "no-overflow" mode which is used when an ADD,
SUB, NEG, or MPY insn is used to set the condition code. This is
to prevent the combiner from optimising away a following CMP of the
result with zero when a signed conditional branch or load insn
follows.
The problem is a subtle one and deals with the manner in which the
negative condition (N) flag is used on the C4x. This flag does not
reflect the status of the actual result but of the ideal result had
no overflow occurred (when considering signed operands).
For example, 0x7fffffff + 1 => 0x80000000 Z=0 V=1 N=0 C=0. Here
the flags reflect the untruncated result, not the actual result.
While the actual result is less than zero, the N flag is not set
since the ideal result of the addition without truncation would
have been positive.
Note that the while the N flag is handled differently to most other
architectures, the use of it is self consistent and is not the
cause of the problem.
Logical operations set the N flag to the MSB of the result so if
the result is negative, N is 1. However, integer and floating
point operations set the N flag to be the MSB of the result
exclusive ored with the overflow (V) flag. Thus if an overflow
occurs and the result does not have the MSB set (i.e., the result
looks like a positive number), the N flag is set. Conversely, if
an overflow occurs and the MSB of the result is set, N is set to 0.
Thus the N flag represents the sign of the result if it could have
been stored without overflow but does not represent the apparent
sign of the result. Note that most architectures set the N flag to
be the MSB of the result.
The C4x approach to setting the N flag simplifies signed
conditional branches and loads which only have to test the state of
the N flag, whereas most architectures have to look at both the N
and V flags. The disadvantage is that there is no flag giving the
status of the sign bit of the operation. However, there are no
conditional load or branch instructions that make use of this
feature (e.g., BMI---branch minus) instruction. Note that BN and
BLT are identical in the C4x.
To handle the problem where the N flag is set differently whenever
there is an overflow we use a different CC mode, CC_NOOVmode which
says that the CC reflects the comparison of the result against zero
if no overflow occurred.
For example,
[(set (reg:CC_NOOV 21)
(compare:CC_NOOV (minus:QI (match_operand:QI 1 "src_operand" "")
(match_operand:QI 2 "src_operand" ""))
(const_int 0)))
(set (match_operand:QI 0 "ext_reg_operand" "")
(minus:QI (match_dup 1)
(match_dup 2)))]
Note that there is no problem for insns that don't return a result
like CMP, since the CC reflects the effect of operation.
An example of a potential problem is when GCC
converts (LTU (MINUS (0x80000000) (0x7fffffff) (0x80000000)))
to (LEU (MINUS (0x80000000) (0x7fffffff) (0x7fffffff)))
to (GE (MINUS (0x80000000) (0x7fffffff) (0x00000000)))
Now (MINUS (0x80000000) (0x7fffffff)) returns 0x00000001 but the
C4x sets the N flag since the result without overflow would have
been 0xffffffff when treating the operands as signed integers.
Thus (GE (MINUS (0x80000000) (0x7fffffff) (0x00000000))) sets the N
flag but (GE (0x00000001)) does not set the N flag.
The upshot is that we can not use signed branch and conditional
load instructions after an add, subtract, neg, abs or multiply.
We must emit a compare insn to check the result against 0. */

@findex EXTRA_CC_MODES
@item EXTRA_CC_MODES
A list of additional modes for condition code values in registers
(@pxref{Jump Patterns}). This macro should expand to a sequence of
calls of the macro @code{CC} separated by white space. @code{CC} takes
two arguments. The first is the enumeration name of the mode, which
should begin with @samp{CC} and end with @samp{mode}. The second is a C
string giving the printable name of the mode; it should be the same as
the first argument, but with the trailing @samp{mode} removed.
Condition codes are represented in registers by machine modes of class
@code{MODE_CC}. By default, there is just one mode, @code{CCmode}, with
this class. If you need more such modes, create a file named
@file{@var{machine}-modes.def} in your @file{config/@var{machine}}
directory (@pxref{Back End, , Anatomy of a Target Back End}), containing
a list of these modes. Each entry in the list should be a call to the
macro @code{CC}. This macro takes one argument, which is the name of
the mode: it should begin with @samp{CC}. Do not put quotation marks
around the name, or include the trailing @samp{mode}; these are
automatically added. There should not be anything else in the file
except comments.
You should only define this macro if additional modes are required.
A sample @file{@var{machine}-modes.def} file might look like this:
A sample definition of @code{EXTRA_CC_MODES} is:
@smallexample
#define EXTRA_CC_MODES \
CC(CC_NOOVmode, "CC_NOOV") \
CC(CCFPmode, "CCFP") \
CC(CCFPEmode, "CCFPE")
CC (CC_NOOV) /* @r{Comparison only valid if there was no overflow.} */
CC (CCFP) /* @r{Floating point comparison that cannot trap.} */
CC (CCFPE) /* @r{Floating point comparison that may trap.} */
@end smallexample
When you create this file, the macro @code{EXTRA_CC_MODES} is
automatically defined by @command{configure}, with value @samp{1}.
@findex SELECT_CC_MODE
@item SELECT_CC_MODE (@var{op}, @var{x}, @var{y})
Returns a mode from class @code{MODE_CC} to be used when comparison
