Use mkdir() instead of _mkdir() for MinGW MinGW-w64 requires the use of mkdir() and MinGW-w32 appears to support both so use mkdir() to allow compilation to work with both versions.
2011-12-18 20:41:21 +01:00
// MinGW only supports mkdir() with a path. If this stops working because
// we need to use _mkdir() for mingw-w32 and mkdir() for mingw-w64 look
// at using the autoconf AX_FUNC_MKDIR macro to figure this all out.
Compiler fixes for MinGW. In MinGW, when parameters are passed to vhdlpp by ivlpp, single quotes are treated as ordinary characters. Use double quotes instead, as is done in the driver. Also, MinGW does not have a standard mkdir() function, so we need to convert calls to mkdir() into calls to _mkdir().

Code generator for architectures. Separate elaboration from code generation in the Entity, and add to Architectures a code generator to handle some simple cases. At this point we have the basic structure for the VHDL compiler.
