Hi Christophe,
2017-04-24 10:25 GMT+02:00 Christophe Lyon :
the patch in the attachment fixes a memory leak by auto-deallocating
the allocatable components of an allocatable intent(out) argument.
Regtests cleanly on x86_64-linux-gnu. Ok for trunk?

One issue in PR79201 is that we don't sink pure/const calls which is
what the following simple patch fixes.
Bootstrap and regtest running on x86_64-unknown-linux-gnu.

I have tested the following patch to remove (where easy) dead code
in the way of sinking.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.
