|
|

|
|
<p>At this point we take a detour from the impersonal tone of the rest of
|
||
|
|
the manual. Admit it: if you’ve read this far into the compiler
|
||
|
|
internals manual, you are a junkie. Perhaps a course at your university
|
||
|
|
left you unsated, or perhaps you’ve always harbored a desire to hack the
|
||
|
|
holy of computer science holies: a compiler. Well you’re in good
|
||
|
|
company, and in a good position. Guile’s compiler needs your help.
|
||
|
|
</p>
|
||
|
|
<p>There are many possible avenues for improving Guile’s compiler.
|
||
|
|
Probably the most important improvement, speed-wise, will be some form
|
||
|
|
of optimized ahead-of-time native compilation with global register
|
||
|
|
allocation. A first pass could simply extend the compiler to also emit
|
||
|
|
machine code in addition to bytecode, pre-filling the corresponding JIT
|
||
|
|
data structures referenced by the <code class="code">instrument-entry</code> bytecodes.
|
||
|
|
See <a class="xref" href="Instrumentation-Instructions.html">Instrumentation Instructions</a>.
|
||
|
|
</p>
|
||
|
|
<p>The compiler also needs help at the top end, adding new high-level
|
||
|
|
compilers. We have JavaScript and Emacs Lisp mostly complete, but they
|
||
|
|
could use some love; Lua would be nice as well, but whatever language it
|
||
|
|
is that strikes your fancy would be welcome too.
|
||
|
|
</p>
|
||
|
|
<p>Compilers are for hacking, not for admiring or for complaining about.
|
||
|
|
Get to it!
