Hi WY, Apologies for exceptionally slow response. The patch you referenced is mostly OK but I would like to get the MIPS16 check changed to a configure time check for MIPS16 support rather than checking for r5900. I.e. I think we should have GCC raise an error for -march=r5900 -mips16 and then a configure time check using just -mips16 would fail. That can then be used to choose whether to build the mips16 code instead of this: + if test x$with_arch != xr5900; then + tmake_file="$tmake_file mips/t-mips16" + fi This change should also make it possible to have mips.exp simply skip the mips16 tests for r5900 without having to tell it explicitly about r5900.
