Hi ! To improve a program in C language, I want to use -fprofile-generate and -fprofile-use, but, my program is a backtrack algorithm that is not going to end. Consequently, I have to compile once with -fprofile-generate, run the program, then end it thanks to a kill -SIGUSR1 and compile another time with -fprofile-use, but, in a makefile, I cannot use create a toto.o rule twice which is what I need to create the good toto.gdca file first, then use this file for another compilation. So, I'm looking for an idea to compile twice the same program (with the same .o) with different option. Could you help me ?
