I see the following failure while compiling vect-64.con power:
unrecognizable insn:
(insn 129 337 130 5
/home/razya/mainline_r131741/gcc/gcc/testsuite/gcc.dg/vect/vect-64.c:23
(parallel [
(set (reg:V4SI 241 [ vect_cst_.61 ])
(reg:V4SI 315))
(unspec [
(const_int 0 [0x0])
] 196)
]) -1 (nil))
The dump file vect-64.c.136r.unshare
still shows a the correct insn:
(insn 129 128 130 5
/home/razya/mainline_r131741/gcc/gcc/testsuite/gcc.dg/vect/vect-64.c:23
(parallel [
(set (reg:V4SI 241 [ vect_cst_.61 ])
(mem/c/i:V4SI (plus:SI (reg/f:SI 115 virtual-stack-vars)
(const_int 60696 [0xed18])) [6 S16 A128]))
(unspec [
(const_int 0 [0x0])
] 196)
]) -1 (nil))
but then it gets messed somehow, and the expected memory reference is replaced
by a register.
I've also located the revision where this failure started, r131741:
