Re: [PATCH][libcpp] New deferred output pragma

Just so there is no doubt, for me this doesn't meet the bar for a new

I probably agree with such a position (even if I found the proposed extension a little interesting, but probably not enough to be accepted as is). However, this brings another question in mind: making this extension & patch a plugin.

I don't know enough libcpp/ & I did not looked very closely into the patch. However, I believe that such a need is typical for plugins.

Then the question becomes: does the current trunk provides enough plugin hooks to make such a plugin? I would guess that some hooks are missing (but I am not sure of that: we have plugin hooks for pragmas, but perhaps not inside libcpp).

I would hence invite the IceraSami people needing this patch & deferred output pragma to:

a. investigate what (small) plugin hooks might be missing to implement their extension as a plugin.

b. propose (if needed) to GCC the small patch providing the necessary extra hooks. (I would expect such a patch to be much much smaller than their original one, and probably easier to be accepted)

c. implement their new pragma in a plugin, and distribute that plugin under GPLv3 license.
