[Bug testsuite/34894] New: Some compile tests require trampolines even when the target sets no_trampolines

[pmarques at grupopie dot com]

When trying to run the testsuite for the avr target I get these failures from
gcc.c-torture/compile:

gcc.c-torture/compile/20010226-1.c:6: internal compiler error: trampolines not
supported
gcc.c-torture/compile/20050122-2.c:7: internal compiler error: trampolines not
supported
gcc.c-torture/compile/nested-1.c:9: internal compiler error: trampolines not
supported
gcc.c-torture/compile/pr27889.c:3: internal compiler error: trampolines not
supported

All except 20050122-2.c seem to be clear cases where trampolines are needed.
20050122-2.c might be able to work without requiring trampolines, but the
address of a nested function is taken, nonetheless, so I guess we can not
consider it a bug for gcc to use trampolines to compile it.

patch with possible fix


This patch fixes the test cases, by #ifndef'ing the relevant code when
NO_TRAMPOLINES is defined
