Don't create SSA names until in SSA form
An upcoming patch adds a fold from hypot(x,x) to fabs(x)*sqrt(2).
This is unusual in that it could trigger in the gimplifier but would
require new SSA names to be created. This patch makes sure that we
use the usual:
if (gimple_in_ssa_p (cfun))
res = make_ssa_name (type);
else
res = create_tmp_reg (type);
formula to cope with cases where we're not yet in SSA form.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
gcc/
* gimple-match-head.c (maybe_push_res_to_seq): Use create_tmp_reg
instead of make_ssa_name if not yet in SSA form.
