Subject: [Bug target/60111] [SH] ICE compiling Newlib
Date: Sat, 01 Mar 2014 14:56:00 -0000	[thread overview]
Message-ID: <bug-60111-4-nuYlp7yCbx@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #2 from Oleg Endo <olegendo at gcc dot gnu.org> ---
In gen_ashift the assert
    gcc_assert (satisfies_constraint_P27 (n_rtx));

fires, which means that the requested shift amount is not 1, 2, 8 or 16.

In gen_shifty_hi_op the function gen_ashift is invoked with the shift amount
values taken from the ext_ashl_lshr_seq table, which contains the allowed shift
amounts only.
I don't see a problem in sh.c.  Maybe it's a indeed a problem of the host
compiler.
