On powerpc*-unknown-linux-gnu several vectorization tests ICE in verify_stmts
after the error message "invalid conversion in gimple call":
gcc.dg/vect/no-scevccp-outer-7.c
gcc.dg/vect/no-scevccp-outer-13.c
gcc.dg/vect/slp-perm-1.c
gcc.dg/vect/slp-perm-2.c
gcc.dg/vect/slp-perm-3.c
gcc.dg/vect/slp-perm-8.c
gcc.dg/vect/vect-reduc-dot-u8b.c
The failures begin with this patch:

Here's a minimized testcase usable with a powerpc-linux cross compiler:
---------------------------------------------------------------
extern unsigned char X[64] __attribute__ ((__aligned__(32)));
extern unsigned char Y[64] __attribute__ ((__aligned__(32)));
unsigned short
foo (int len) {
int i;
unsigned short result = 0;
for (i=0; i<len; i++) {
result += (unsigned short)(X[i] * Y[i]);
}
return result;
}
---------------------------------------------------------------
The failures for gcc.dg/pr34989-1.c (PR39959) and
gcc.dg/struct/wo_prof_double_malloc.c (PR39940) begin with the same patch on
powerpc*-linux.

I think this is really PR 30210.
