r201505 and r201508 converted passes to C++ classes, with the gate
and execute hooks becoming virtual functions, allowing for the
possibility of storing state within pass instances, rather than
statically allocating it. This has benefits for state-isolation,
for example within my JIT branch, which invokes the compiler
multiple times in one process.
The following patches convert the additional function pointer hooks
in ipa_opt_pass_d to be virtual functions, for similar reasons.
The changes are analogous to those earlier patches for gate and
execute.
It is in two parts:
* patch 1 of 2 is handwritten: it updates the core ipa declarations
to use virtual functions rather than function pointers, with a
"const struct ipa_pass_data" holding metadata such as flags to
determine if a hook is present (since we can't portably check
a virtual function against NULL).
* patch 2 of 2 converts all of the passes themselves to this new API.
It is automatically generated using a refactoring script:
refactor_ipa_passes.py within
https://github.com/davidmalcolm/gcc-refactoring-scripts
There is a test suite for the refactoring script within the same
repository: test_refactor_ipa_passes.py
Successfully bootstrapped and regtesting on x86_64-unknown-linux.
OK for trunk?
