[Ada] Avoid spurious errors on dimensionality checking in GNATprove

2019-08-13 Thread Pierre-Marie de Rodat
Complete the partial treatment that was started in r273405.  Instead of
checking for the special case of nodes inside inlined bodies at the call
site, check for this condition inside the top-level procedures called
for dimensionality checking.

There is no impact on compilation.

Tested on x86_64-pc-linux-gnu, committed on trunk

[Ada] Avoid spurious errors on dimensionality checking in GNATprove

2019-07-11 Thread Pierre-Marie de Rodat
In the special GNATprove mode of the frontend, automatic inlining is
performed, which may lead to spurious errors on dimensionality checking.
Avoid performing this checking on inlined code, which has already been
checked for dimensionality errors.

There is no impact on compilation.
