no_trampolines Dejagnu switch will omit many but not all trampoline dependent
tests.
Nested function are ok - but anything that takes an address of a nested function will use trampoline.
They can be hard to find as testcases are devilish at hiding that part!
For example:
gcc.c-torture/compile/nested-1.c
will fail.
There are quite a few like this. I am hoping to get round to providing patches to correct these test cases. You will find a few more listed
in this valiant attempt of 2005:
