Umm, that was supposed to be:
=== gcc Summary ===
-# of expected passes 122244
-# of unexpected failures 1852
+# of expected passes 122428
+# of unexpected failures 1484
# of unexpected successes 5
# of expected failures 721

Verification of the revert of commit c605a8bf9270 with GCC 11 shows a
pair of regressions in libstdc++-v3 though:
-FAIL: 26_numerics/random/ranlux48.cc execution test
-FAIL: 26_numerics/random/ranlux48_base.cc execution test
+FAIL: 26_numerics/random/ranlux48.cc (test for excess errors)
+FAIL: 26_numerics/random/ranlux48_base.cc (test for excess errors)
and the excess errors are:
during RTL pass: postreload
.../libstdc++-v3/testsuite/26_numerics/random/ranlux48.cc: In function 'void
test01()':
.../libstdc++-v3/testsuite/26_numerics/random/ranlux48.cc:36: internal compiler
error: in cselib_invalidate_regno, at cselib.c:2422
and:
during RTL pass: postreload
.../libstdc++-v3/testsuite/26_numerics/random/ranlux48_base.cc: In function
'void test01()':
.../libstdc++-v3/testsuite/26_numerics/random/ranlux48_base.cc:36: internal
compiler error: in cselib_invalidate_regno, at cselib.c:2422
respectively (we have a pair of test cases that fail anyway, but an ICE is
I think an escalation of a failure in comparison to an execution failure;
I haven't debugged what the causes of the respective execution failures
are or what the exact cause of the ICEs is at this point).
No changes elsewhere throughout all the testsuites.
