This is a dg-do compile test using check-function-bodies. Under slim
LTO (-flto -fno-fat-lto-objects) a compile-only run emits only LTO
bytecode with no assembly, and no LTRANS output is produced since the
test never links, so check-function-bodies finds no output file to scan.
Unlike scan-assembler*, check-function-bodies has no required-options
hook to force -ffat-lto-objects. Skip the -flto variant.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/ext-dce-3.c: Skip under -flto.
* gcc.target/riscv/ext-dce-4.c: Skip under -flto.
