Module entrypoint;

DMD-generated module __entrypoint where the C main resides

Module rootHasMain;

Module in which the D main is

void genCmain(Scope* sc);

Generate C main() in response to seeing D main().

This function will generate a module called __entrypoint, and set the globals entrypoint and rootHasMain.

This used to be in druntime, but contained a reference to Dmain which didn't work when druntime was made into a dll and was linked to a program, such as a C++ program, that didn't have a Dmain.

Parameters:

Scope* sc Scope which triggered the generation of the C main, used to get the module where the D main is.

int main();

Entry point which forwards to tryMain.

Returns:

Return code of the application

void addDefaultVersionIdentifiers();

Add default version identifier for dmd, and set the target platform in global. https://dlang.org/spec/version.html#predefined-versions

Needs to be run after all arguments parsing (command line, DFLAGS environment variable and config file) in order to add final flags (such as X86_64 or the CRuntime used).
