Here is the DT_AUXILIARY patch for the shared libgcc. After some experiments, I believe we shouldn't even need libgcc.so under Linux. We just set the DT_AUXILIARY to libgcc.so$(libgcc.so-version). We will only have /lib/libgcc.so$(libgcc.so-version) which is symlinked to /lib/libgcc-3.0.so. /lib/libgcc.so$(libgcc.so-version) is hidden from user. Everything is still linked with libgcc.a. I will provide the libgcc framework soon. It should be trivial to update /lib/libgcc-3.0.so from a new gcc installation. -- H.J. Lu (hjl@gnu.org) -- 2000-07-14 H.J.
