#434 Substitute __cpp__ code insertions by PEARL constructs

[Rainer Müller]

Many test contain __cpp__ statements to simulate compiler output, which was not provided by the date, the test was created.
These C++ code fragments should become replaced by PEAR statements

[Rainer Müller]

__cpp__ is used in

Proposal

Supply an interface for c++-written extensions to the OpenPEARL-library

• add PEARL-modules for specific platforms
• they become compiled and added to the runtime library

Example:

MODULE(OpenPEARL_Linux):
PROBLEM;
setExitCode: PROC(FIXED(31) x) GLOBAL;
    __cpp__("pearlrt::Control::setExitCode(x.x);");
END;

getHostName: PROC RETURNS CHAR(80);
    DCL hostname CHAR(80);
    __cpp__("gethostname(_hostname.data,80);");
    RETURN(hostname);
END;    

Idea of Implementation

We need a new step in the build process

current steps

1. build: configuration/include/autoconf.h configuration/include/auto.conf \
   runtime compiler errorChecker static_analyzer
2. install the components to /usr/local/OpenPEARL

additional steps:

1. build extensions like simulators and platform specific extensions with the installed compiler
2. add the created objects the the OpenPEARL-libraries
