-Likewise, binutils has no idea about any of these new targets either, so we
-fix that up too.. now we're able to actually build a real toolchain for
-sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
-inept targets than that one, really. Go look, I promise).

-Subject: [PATCH] xtensa: fix memory corruption by broken sysregs
-
-In some xtensa configurations there may be system/user registers in
-xtensa-modules with negative index. ISA initialization for such config
-may clobber heap and result in program termination.
-Don't update lookup table entries for register with negative indices.
-They are not directly accessible via RSR/WSR/XSR or RUR/WUR, so this
-change should not affect processing of valid assembly/binary code.
