Some way to turn off the use of an included stdc++.h PCH file in the libstdc++
test suite is needed. As part of
libstdc++/20534
I propose:
+ // { dg-options "-D__GLIBCXX__=99999999" }
+ // NB: This is done to force any generated and possibly included PCH
+ // to be invalid.
which will work.
Paolo suggests hookizing this into:
dg-do compile-no-pch
Sounds like a good idea.
In addition, it looks like a review of the do-compile testcases in the libstdc++
are needed, to see if some expect to be compiled without PCH. (This is
absolutely the case.)
