Extending SSCLI 2.0
-------------------

Shared Source Common Language Infrastructure 2.0 Release can be found at:

Be sure to also install the prerequired software (also Perl).

After decompression to lets say "d:\sscli20\" follow the instructions in
rotor.pdf starting from page 56 (more exactly page 72).

Files needing modifying:
\clr\src\fjit\fjit.cpp
\clr\src\fjit\fjit.h
\clr\src\fjit\fjitdef.h
\clr\src\inc\opcode.def  - modify the line having string rep "unused" and
                           bytecode 0xA6 with the line specified in
                           rotor.pdf page 76 (with the correction of 0xA6
                           instead of 0xA3)
\clr\src\vm\vertable.h  - page 78 in the pdf (careful CEE_UNUSED21, ..)

Copy the file (found in this archive) opcodegen.pl to \clr\src\inc\
and then at the command prompt:
c:\sscli20\clr\src\inc> perl opcodegen.pl

Overwrite-copy the resulting five .cs files (spawned in the same dir)
to \clr\src\bcl\system\reflection\emit\

Go to the root of SSCLI in the command prompt and enter:
> env
> buildall
It should take a long time to build completely.

The warnings displayed are normal, as stated in the SSCLI 2.0 readme's.


Create a simple.cs file containing:
double a = 3;
double b = 2;
System.Console.WriteLine(""+ a*b );

Compile it: csc simple.cs (be sure to have runned <root>\"env.bat debug"
                           in this console, or else the official .Net
                           compiler will be launched; env needs the
                           parameter "debug" or else ilasm will fail)
Run-test it: clix simple

Disassemble by: ildasm simple.exe > simple.il
Modify simple.il replacing "mul" with "exp" in the code.
Assemble back: ilasm simple.il

Run: clix simple

Launching simple.exe directly will not run - it would use the .Net CLI.
