Re: [WIP v3] Introduce mescc.a for division algorithm and move the latter there.

[Danny Milosavljevic]

Hi,

with WIP v3 I get on armhf:

(1) gcc-lib

Failed tests:

>lib/tests/scaffold/7l-struct-any-size-array-simple.c
>lib/tests/scaffold/7r-sign-extend.c

(2) mescc-lib

# XFAIL:

exit status 1 probably means that f.func (2) != 1;

And that's *after* I implemented setjmp :P
I guess that one doesn't work yet...

Also, on i686-linux with patch applied:

$ guix build  -K -s i686-linux -f guix.scm 
/gnu/store/3ry6gxn6s5nzjnbs7vlf2q2zvz9zx5ql-mes.git-0.22-0.834e97d

I'd say the patch WIP v3 "Introduce mescc.a for division algorithm and move the 
latter there" makes things a lot better and we can use it for real.

Note that I didn't test the Hurd (and it probably won't work because we don't 
implement a __raise function for it).
