Hello, Note that slang is a subset of smalltalk. The Slang compiler does not allow to compile smalltalk to C. It allows to compile a smalltalk with restricted message sends and classes to C.

However, by having a Slang to C compiler, we're platform-independent, we can compile the C code to x86, x86_64 and ARM quite easily (some part of the VM are already processor dependent, but not so much). Targeting direct machine code implies evolving the Slang compiler for each new assembly code we support. It sounds like a lot of engineering work compared to our resources and the gain. > > - would targetting LLVM-IR be of interest? > > If you compile the C code with Clang instead of gcc, which starts to be the case because of the lack of support for gcc in the latest Mac OS X, you are already using LLVM IR because Clang uses it. As the VM use the GNU C extensions to improve performance, I do not think that targeting directly the LLVM IR would greatly improve performance. So it sounds like quite some engineering work for no gain. However, I think Ronie was interested in doing such work. If he succeeds and reports performance improvement, then we can consider using his compiler to compile the VM. > Thierry > > 2014-09-15 12:29 GMT+02:00 p...@highoctane.be <p...@highoctane.be>: > > Slang has been externalized by Pavel.
