I guess there is a conflict with the "!" values in --with-multilib-list=m1,m2,m2e,m4,m4-single,m4-single-only,m2a,m2a-single,!m2a,!m2a-single passed to the sh-linux compiler

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55351 --- Comment #2 from dhowells at redhat dot com 2012-11-20 15:09:42 UTC --- The first hunk of the patch that adds: MULTILIB_EXCEPTIONS = *m5-64media* *m5-64media-nofpu* to gcc/config/sh/t-linux causes the sh-linux-gnu build to fail. Commenting out this line allows both sh- and sh64-linux-gnu to build.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55351 --- Comment #1 from Nick Clifton 2012-11-19 16:01:36 UTC --- Created attachment 28732 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28732 Fixes to allow libgcc to build for the sh64-linux target I am no SH expert, so this patch may well be wrong. But it does allow libgcc to built (for all supported multilibs) for the sh64-linux target. There seem to be three problems: 1. As reported in this PR, the sdivsi3 function is being built for the L_div_table target when it clearly uses instructions that are not supported by the target SH variant. I have assumed that this is a mistake and so stopped the function from being built for the m5-compact multilib. 2. The udiv_qrnnd_16 function is not being built. It is built for non-Linux Sh targets, so I have assumed that it is an oversight and added it to the list of functions to build. 3. The m5-media64 and m5-media64-nofpu multilibs need the linker to support a shlefl64_linux emulation. The linker does not do this, so I have suppressed all multilibs based on these options.
