Ok.

These sort of updates will now be obvious to you, now that you have gotten your

[PATCH V6 08/11] bpf: make target-supports.exp aware of eBPF

2019-08-29 Thread Jose E. Marchesi 
This patch makes the several effective target checks in
target-supports.exp to be aware of eBPF targets.

gcc/testsuite/ChangeLog:

* lib/target-supports.exp
(check_effective_target_trampolines): Adapt to eBPF.
(check_effective_target_stack_size): Likewise.
(dg-effective-target-value): Likewise.
(check_effective_target_indirect_jumps): Likewise.
(check_effective_target_nonlocal_goto): Likewise.
(check_effective_target_global_constructor): Likewise.
(check_effective_target_return_address): Likewise.
