Yes, changed in V2 patch.

Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ok for trunk?


Matching constraints are used in these circumstances. More precisely,
the two operands that match must include one input-only operand and
one output-only operand. Moreover, the digit must be a smaller number
than the number of the operand that uses it in the constraint.

In pr107057, the 2 operands in the pattern are both input operands.

gcc/ChangeLog:

	PR target/107057
	* config/i386/sse.md (*vec_interleave_highv2df): Remove
	constraint 1.
	(*vec_interleave_lowv2df): Ditto.
	(vec_concatv2df): Ditto.
	(*avx512f_unpcklpd512<mask_name>): Ditto and renamed to ..
	(avx512f_unpcklpd512<mask_name>): .. this.
	(avx512f_movddup512<mask_name>): Change to define_insn.
	(avx_movddup256<mask_name>): Ditto.
	(*avx_unpcklpd256<mask_name>): Remove constraint 1 and renamed
	to ..
	(avx_unpcklpd256<mask_name>): .. this.
	* config/i386/i386.cc (ix86_vec_interleave_v2df_operator_ok):
	Disallow MEM_P (op1) && MEM_P (op2).

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr107057.c: New test.

OK with two small adjustments.

Thanks,

I think you should leave nonimmediate_operand here with "m" predicate.
Reload is able to move the register to the memory, and it is
beneficial to allow registers for possible combine opportunities.

Also here, leave nonimmediate_operand.
