This patch appears to create a *second* file called libgcc_tm.h, so there is one created in gcc/ and one in libgcc/, which seems incredibly confusing. By all means move the libgcc_tm.h logic to libgcc/ (though tm.h will need to continue to include libgcc_tm.h for the target, until the transition away from tm.h target macros in target code is complete and code includes libgcc_tm.h directly instead), but don't have two headers with the same name in different build directories. I interpreted Rainer's comment as meaning that a libgcc/config/mips/mips-lib.h (or similar) file would need to be created and inserted in the right place in libgcc_tm_file for the large number of targets presently putting mips.h in tm_file. -- Joseph S.
