Hi, PR 90581 (provide an option to adjust the maximum depth of nested #include) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90581
is to add a new cpp option -fmax-inlcude-depth to set the maximum depth of
nested #include.
'-fmax-include-depth=DEPTH'
Set the maximum depth of the nested include. The default value is
200.
Please check the attached patch.
I have done bootstrap and regression test on X86, no any issue.
thanks a lot.
Qing.
