Bug ID: 90581
Summary: provide an option to adjust the maximum depth of
nested #include
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: qinzhao at gcc dot gnu.org
Target Milestone: ---
for some large complicate applications, sometimes the depth of nested #include
might be very big, exceeding the current hard-coded limit 200:
directives.c:
if (pfile->line_table->depth >= CPP_STACK_MAX)
cpp_error (pfile, CPP_DL_ERROR, "#include nested too deeply");
internal.h:
#define CPP_STACK_MAX 200
This PR is to request a first class option for users to adjust this limit
during compilation time in order to compile the large application successfully.
