Bug #: 53635 Summary: --enable-build-with-cxx: stage1-gcc shrinks from 1.1 GiB to 0.4 GiB Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassig...@gcc.gnu.org ReportedBy: tschwi...@gcc.gnu.org Blocks: 44433 Host: i686-pc-linux-gnu Target: i686-pc-linux-gnu Build: i686-pc-linux-gnu As reported in <http://gcc.gnu.org/ml/gcc/2012-06/msg00107.html>: when --enable-build-with-cxx is enabled, the size of the build directory stage1-gcc shrinks (!) from 1.1 GiB to 0.4 GiB, such that the whole build tree then occupies 2.6 GiB instead of 3.2 GiB. I did notice that the C build uses -fkeep-inline-functions, and the C++ build doesn't (my logs, and confirmed in the top-level configure.ac), but don't know if that is the (sole) reason; I have not looked at this in more detail -- but 0.6 GiB or 60 % less is quite a bit. This may be a non-issue, but someone should declare it so.
