Bug ID: 86030
Summary: specs file processing does not create response files
for input directories
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: tnfchris at gcc dot gnu.org
Target Milestone: ---
Target: mingw32
Similar to #45157 and #45749,
GCC does not use response files for %D and %I handling (see do_spec_1), so if
you have a project which contrains a lot of Includes or library directories cc1
or collect2 respectively will overflow the commandline limit on Windows and
error out.
It looks like a similar check/call as handling %i and %o needs to be added for
%D and %I (calling create_at_file to create response files for these).
This is causing problems for the GHC Haskell compiler when lots of packages are
used.
