David,
I think this could be added to the pr71779 test case:
test_pr71779 ()
{
/* Only run this tests for target==aarch64. */
#ifndef GCC_AARCH64_H
+#ifndef I386_OPTS_H
return;
+#endif
#endif
rtl_dump_test t (SELFTEST_LOCATION, locate_file ("pr71779.rtl"));
dataflow_test df_test;
tem = cse_main (get_insns (), max_reg_num ());
ASSERT_EQ (0, tem);
+ ASSERT_FALSE (REG_POINTER (SET_DEST (PATTERN (get_insn_by_uid (1047)))));
}
at least last time when I tried it, this was able
to reproduce the invalid transformation.
It worked for aarch64 and x86_64, not sure if it will work for
i686-pc-linux-gnu too...
Bernd.
