re PR middle-end/25724 (Emits call to __cmpdi2 for long long comparison in switches) PR middle-end/25724 * dojump.c (do_jump): Call do_compare_rtx_and_jump. (do_jump_parts_zero_rtx): New function renamed from do_jump_parts_equality_rtx. Made static. Add a mode argument. (do_jump_parts_equality_rtx): New function split out from do_jump_parts_equality. Old implementation renamed as above. Call do_jump_parts_zero_rtx if either operand is zero. (do_jump_parts_equality): Call do_jump_parts_equality_rtx to do all of the heavy lifting. (do_compare_rtx_and_jump): Handle multi-word comparisons by calling either do_jump_by_parts_greater_rtx or do_jump_by_parts_equality_rtx. * expr.h (do_jump_by_parts_equality_rtx): Remove prototype. * expmed.c (do_cmp_and_jump): Now multi-word optimization has moved to do_compare_rtx_and_jump, call it directly. * stmt.c (do_jump_if_equal): Remove static prototype.

/* Generate code to extract a byte-field from STR_RTX
containing BITSIZE bits, starting at BITNUM,
and put it in TARGET if possible (if TARGET is nonzero).
Regardless of TARGET, we return the rtx for where the value is placed.
STR_RTX is the structure containing the byte (a REG or MEM).
UNSIGNEDP is nonzero if this is an unsigned bit field.
MODE is the natural mode of the field value once extracted.
TMODE is the mode the caller would like the value to have;
but the value may be returned with type MODE instead.
TOTAL_SIZE is the size in bytes of the containing structure,
or -1 if varying.
If a TARGET is specified and we can store in it at no extra cost,
we do so, and return TARGET.
Otherwise, we return a REG of mode TMODE or MODE, with TMODE preferred
if they are equally easy. */

/* Extract a bit field using shifts and boolean operations
Returns an rtx to represent the value.
OP0 addresses a register (word) or memory (byte).
BITPOS says which bit within the word or byte the bit field starts in.
OFFSET says how many bytes farther the bit field starts;
it is 0 if OP0 is a register.
BITSIZE says how many bits long the bit field is.
(If OP0 is a register, it may be narrower than a full word,
but BITPOS still counts within a full word,
which is significant on bigendian machines.)
UNSIGNEDP is nonzero for an unsigned bit field (don't sign-extend value).
If TARGET is nonzero, attempts to store the value there
and return TARGET, but this is not guaranteed.

do it as the IOR of two shifts. I.e., to rotate A
by N bits, compute (A << N) | ((unsigned) A >> (C - N))
where C is the bitsize of A.
It is theoretically possible that the target machine might
not be able to perform either shift and hence we would
be making two libcalls rather than just the one for the
shift (similarly if IOR could not be done). We will allow
this extremely unlikely lossage to avoid complicating the

/* Choose a minimal N + 1 bit approximation to 1/D that can be used to
replace division by D, and put the least significant N bits of the result
in *MULTIPLIER_PTR and return the most significant bit.
The width of operations is N (should be <= HOST_BITS_PER_WIDE_INT), the
needed precision is in PRECISION (should be <= N).
PRECISION should be as small as possible so this function can choose
multiplier more freely.
The rounded-up logarithm of D is placed in *lgup_ptr. A shift count that
is to be used for a final right shift is placed in *POST_SHIFT_PTR.
Using this function, x/D will be equal to (x * m) >> (*POST_SHIFT_PTR),
where m is the full HOST_BITS_PER_WIDE_INT + 1 bit multiplier. */

We try to generate special code for division and remainder when OP1 is a
constant. If |OP1| = 2**n we can use shifts and some other fast
operations. For other values of OP1, we compute a carefully selected
fixed-point approximation m = 1/OP1, and generate code that multiplies OP0
by m.
In all cases but EXACT_DIV_EXPR, this multiplication requires the upper
half of the product. Different strategies for generating the product are
implemented in expand_mult_highpart.
If what we actually want is the remainder, we generate that by another
by-constant multiplication and a subtraction. */

If so, pick a wider mode in which we can do the operation. Convert
to that mode at the start to avoid repeated conversions.
First see what operations we need. These depend on the expression
we are evaluating. (We assume that divxx3 insns exist under the
same conditions that modxx3 insns and that these insns don't normally
fail. If these assumptions are not correct, we may generate less
efficient code in some cases.)
Then see if we find a mode in which we can open-code that operation
(either a division, modulus, or shift). Finally, check for the smallest
mode for which we can do the operation with a library call. */
