--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Bisecting:
- Caused by 'maskload else' support patches set:
- fails since r15-5383 in various ways, but the INSN fail
exists since r15-5387.
Namely:
* WORKING - r15-5382-g5214ddb464aab6
(Robin Dapp / docs: Document maskload else operand and behavior.)
* FAILS - r15-5383-g8f68d9cb7897df
(Robin Dapp / ifn: Add else-operand handling.)
but with a different error:
during RTL pass: expand
input3.i:14:18: internal compiler error: in gimple_call_arg, at gimple.h:3346
0x208cf45 internal_error(char const*, ...)

gcc/internal-fn.cc:350
0xda2154 expand_partial_load_optab_fn
gcc/internal-fn.cc:3074
* FAILS - r15-5384-g6b6bd53619fd11
(Robin Dapp / tree-ifcvt: Add zero maskload else value.)
But again differently:
gcc/tree-if-conv.cc: In function ‘gimple*
predicate_load_or_store(gimple_stmt_iterator*, gassign*, tree)’:
gcc/tree-if-conv.cc:2562:18: error: ‘vect_get_mask_load_else’ was not declared
in this scope; did you mean ‘vect_get_load_cost’?

| vect_get_load_cost
* FAIL - r15-5385-g634ae740f5a839
(Robin Dapp / vect: Add maskload else value support.)
* FAIL - r15-5386-ga166a6ccdc6c3d
(Robin Dapp / aarch64: Add masked-load else operands.)
(Both fail identical as the latter only has aarch64 changes:)
