I was trying to understand the exact meaning of a loose statement
floating around ("gcc has moved to C++ from version 4.7 onwards).I reckon from http://gcc.gnu.org/wiki/gcc-in-cxx that now gcc is compiled using C++. However, the very first line of the description confused me. It says:
GCC has been building stages 2 and 3 in C++ mode for a while.
My understanding was that stage 2 is built using the compiler created in stage 1 and stage 3 is built using the compiler created in stage 2. (Please see slide 17/53 in http://www.cse.iitb.ac.in/grc/gcc-workshop-12/downloads/slides/gccw12-config-build.pdf). Can someone tell me what is the meaning of building stage 2 in C++ mode? If I restrict my languages (using --enable-languages) to C, how can stage 2 be built in C++ mode? Or is it that regardless of the choice given using --enable-languages option, internally C and C++ compiler are created anyway? The build logs do not seem to bear out the above statement. Thanks and regards, Uday. -- ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Dr. Uday Khedker Professor Department of Computer Science & Engg.
