In same cases, like gcc/testsuite/gcc.dg/pr78148.c in RISC-V, there will
be only 1 operand when SET_SRC in create_pre_exit. For example as below.
(insn 13 9 14 2 (clobber (reg/i:TI 10 a0))
"gcc/testsuite/gcc.dg/pr78148.c":24:1 -1
(expr_list:REG_UNUSED (reg/i:TI 10 a0)
(nil)))
Yes, as mentioned Jeff I have some work in that scope.
The first is related to address computation when it has a large constant
part.
Suppose we have this code:
int consume (void *);
int foo (void) {
int x[1000];
return consume (x);
}
before IRA we have the following s

before this patch does not follow the updated requrements, and this
patch is intended to implement it.
Like the support conditional neg (r12-4470-g20dcda98ed376cb61c74b2c71),
this just adds conditional not too.
Also we should be able to turn `(a ? -1 : 0) ^ b` into a conditional
not.
OK? Bootstrapped and tested on x86_64-linux-gnu and aarch64-linux-gnu.
