Re: How to avoid stack calling for trapoline code?

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:
