Re: [gobo-eiffel-develop] New GC for Gobo -- Progress report

[Howard T. <how...@di...>]

Hi Paul,

As regards shared-libraries, for incremental compilation during development I am
envisaging that a generated executable will be split between a compile-every-time
base program, a shared-library containing routines generated 'last time' [where a
previous compilation has taken place], and one or more 'update' shared-libraries,
with some dynamic selection at run-time of most-recently generated routines from
the shared-library set referenced by the base program.

The compiler will use dynamic library loading and call-backs to establish the
available code signatures that are available, where a signature includes any and
all types, arguments, results, options etc that affected code generation, and
generate a new base program and shared-library updates.

I am also working on a set of LLVM style classes to generate LLVM assembler
code and [eventually] machine code directly, at least for Linux/ELF/X86_64.

My most immediate priority is to achieve GC and threading functionality so that I
can use gec and Eiffel to write long-running multi-threaded programs, of which I
have several future projects in the early planning stages.

I will have a look at the SCons tools ...

Regards,

Howard
