Even simpler testcase:
$ cat testcase.c
float
foo (char c)
{
return (float) c;
}
$ powerpc64le-unknown-linux-gnu-gcc -mpower9-misc -mno-popcntd testcase.c
during RTL pass: split5
testcase.c: In function 'foo':
testcase.c:5:1: internal compiler error: in gen_reg_rtx, at emit-rtl.cc:1167

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
gcc-7 doesn't ICE on the above, so it might be a regression.
