--- Comment #3 from Jozef Lawrynowicz <jozefl.gcc at gmail dot com> --- Created attachment 43433 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43433&action=edit define {u,}mulhipsi3 insns I applied the patch but trunk still ICEs. After defining some insns for "umulhipsi3" and "mulhipsi3" in msp430.md, the build gets a little further, but then a case is encountered where a widen from QI to PSI is attempted. QI != PARTIAL_INT_MODE, so we ICE again. The insns in attached patch are mostly just copied from the mulhisi*, so are almost definitely not correct, but they are at least there for GCC to use in the build.
