+<h3>SPARC</h3>
+ <ul>
+ <li>GCC now supports the LEON series of SPARC V8 processors. The code
+ generated by the compiler can either be tuned to it by means of the
+ <code>--with-tune=leon</code> and <code>-mtune=leon</code> options, or
+ the compiler can be built for the <code>sparc-leon-{elf,linux}</code>
+ and <code>sparc-leon3-{elf,linux}</code> targets directly.</li>
+ <li>GCC has stopped sign/zero-extending parameter registers in the callee,
+ for functions taking parameters with sub-word size, in 32-bit mode since
+ this is redundant with the specification of the ABI. GCC has never done
+ so in 64-bit mode since this is also redundant.</li>

You'd need to ask a SPARC maintainer. :-)
Seriously, it does look good to my eyes, thanks, Eric! The only question
I have is this: I assume <code>--with-tune=leon</code> is a configure
option, whereas <code>-mtune=leon</code> is a GCC option? For those not
so familiar with GNU tools or GCC, it might be helpful to make this
explicit in the description.
