Hi,
Currently when we clone alias we also clone its target and create alias
reference during alias target cloning. This doesn't work in case alias clone
is removed and later is re-created. This patch moves alias reference creation

Hi,
When thunk is cloned, its callee is temporarily set to original thunks's target
which is later also cloned. Thus we should be more careful when clonning
node's thunks. Bootstrapped and tested on x86_64-unknown-linux-gnu. Applied
to trunk.

Hello.
Following patch is fix for the PR. Problem is caused if we fill up
cgraph_thunk_info with some values (e.g. virtual_value != 0)
and further analysis set thunk_p = false. In all situations IPA ICF needs to
reset all fields of the struct as it sets
thunk_p = true.

This patch makes some significant changes to attribute abi_tag.
First, it allows explicit naming of tags on inline namespaces, which
previously always had a tag with the same name as the namespace itself;
this is still the default if no tag is specified.
It also introduces automatic tagging o
