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
