This gives a 4-word result. Since we are only interested in the
|
|
|
|
|
lower 2 words, partial result (3) and the upper words of (2a) and
|
|
|
|
|
(2b) don't need to be calculated. Hence (2a) and (2b) can be
|
|
|
|
|
calculated using non-widening multiplication.
|
|
|
|
|
|
|
|
|
|
(1), however, needs to be calculated with an unsigned widening
|
|
|
|
|
multiplication. If this operation is not directly supported we
|
|
|
|
|
try using a signed widening multiplication and adjust the result.
|
|
|
|
|
This adjustment works as follows:
|
|
|
|
|
|
|
|
|
|
If both operands are positive then no adjustment is needed.
|
|
|
|
|
|
|
|
|
|
If the operands have different signs, for example op0_low < 0 and
|
|
|
|
|
op1_low >= 0, the instruction treats the most significant bit of
|
|
|
|
|
op0_low as a sign bit instead of a bit with significance
|
|
|
|
|
2**(BITS_PER_WORD-1), i.e. the instruction multiplies op1_low
|
|
|
|
|
with 2**BITS_PER_WORD - op0_low, and two's complements the
|
|
|
|
|
result. Conclusion: We need to add op1_low * 2**BITS_PER_WORD to
|
|
|
|
|
the result.
|
|
|
|
|
|
|
|
|
|
Similarly, if both operands are negative, we need to add
|
|
|
|
|
(op0_low + op1_low) * 2**BITS_PER_WORD.
|
|
|
|
|
|
|
|
|
|
We use a trick to adjust quickly. We logically shift op0_low right
|
|
|
|
|
(op1_low) BITS_PER_WORD-1 steps to get 0 or 1, and add this to
|
|
|
|
|
op0_high (op1_high) before it is used to calculate 2b (2a). If no
|
|
|
|
|
logical shift exists, we do an arithmetic right shift and subtract
|
|
|
|
|
the 0 or -1. */

Such a block is preceded by a CLOBBER of the output, consists of multiple
|
1991-12-30 04:19:53 +01:00
|
|
|
|
insns, each setting one word of the output, and followed by a SET copying
|
|
|
|
|
the output to itself.
|
|
|
|
|
|
|
|
|
|
Each of the insns setting words of the output receives a REG_NO_CONFLICT
|
|
|
|
|
note indicating that it doesn't conflict with the (also multi-word)
|
|
|
|
|
inputs. The entire block is surrounded by REG_LIBCALL and REG_RETVAL
|
|
|
|
|
notes.
|
|
|
|
|
|
|
|
|
|
INSNS is a block of code generated to perform the operation, not including
|
|
|
|
|
the CLOBBER and final copy. All insns that compute intermediate values
|
1994-11-22 20:38:02 +01:00
|
|
|
|
are first emitted, followed by the block as described above.

1991-12-30 04:19:53 +01:00
|
|
|
|
|
|
|
|
|
TARGET, OP0, and OP1 are the output and inputs of the operations,
|
|
|
|
|
respectively. OP1 may be zero for a unary operation.

EQUIV, if nonzero, is an expression to be placed into a REG_EQUAL note

If TARGET is not a register, INSNS is simply emitted with no special

INSNS is a list containing all insns emitted in the call.
|
|

These insns leave the result in RESULT. Our block is to copy RESULT
|
|
|
|
|
to TARGET, which is logically equivalent to EQUIV.
|
|
|
|
|
|
|
|
|
|
We first emit any insns that set a pseudo on the assumption that these are
|
|
|
|
|
loading constants into registers; doing so allows them to be safely cse'ed
|
|
|
|
|
between blocks. Then we emit all the other insns in the block, followed by
|
|
|
|
|
an insn to move RESULT to TARGET. This last insn will have a REQ_EQUAL
|
|
|
|
|
note with an operand of EQUIV.

Moving assignments to pseudos outside of the block is done to improve
|
|
|
|
|
the generated code, but is not required to generate correct code,
|
|
|
|
|
hence being unable to move an assignment is not grounds for not making
|
|
|
|
|
a libcall block. There are two reasons why it is safe to leave these
|
|
|
|
|
insns inside the block: First, we know that these pseudos cannot be
|
|
|
|
|
used in generated RTL outside the block since they are created for
|
|
|
|
|
temporary purposes within the block. Second, CSE will not record the
|
|
|
|
|
values of anything set inside a libcall block, so we know they must
|
|
|
|
|
be dead at the end of the block.
|
|
|
|
|
|
1991-12-30 04:19:53 +01:00

Except for the first group of insns (the ones setting pseudos), the
