Re: [Tinycc-devel] A wish for 2018? C->JVM compiler

Hi Charles,

Your implementation using switch has a name, it’s called trampoline 
https://en.wikipedia.org/wiki/Trampoline_(computing).

This is what you have to do when backend does not support native goto, and it’s 
generally the case when you write a compiler having a high level language as 
target. Another solution may be CPS 
https://en.wikipedia.org/wiki/Continuation-passing_style 

 

Sure, tinycc->javascript looks interesting.

This really interests me as well.  I still am working on my 
tinycc-to-javascript environment, and to support "goto" was quite awkward and 
required wrapping all code in functions inside "switch" statements.  I was 
hoping webassembly would accept the request to have a "goto" but as far as I 
understand, there's basically no possible way to do any kind of setjmp but 
that's probably ok because so few applications use it.

This raises another question:  Anyone else interested in a tinycc javscript 
target?

My question is if tinycc could generate JVM code which any java engine can use.

IMHO setjmp/longjmp is probably not very easy to compile to a JVM equivalent.

I am not a Java guy, so not sure if that's what you imagine, but it seems close.

Hi all, I don’t how much it could cost nor it’s even feasible, but it would be 
nice to have a JVM backend. (as other languages already use, see 
https://en.wikipedia.org/wiki/List_of_JVM_languages)

This could be a nice student project.

 

Main goal:

-  Have a portable C on top on JVM

 

Second goals

-  Smooth integration with JDK libs

-  Optional GC

-  Optimization done by JIT

 

Non goals:

-  Speed of compiled program

 

Any university there willing to make this port happen?
