[java-gnome-hackers] Compiler optimizations

[Andrew C. <an...@op...>]

Does anyone know why we aren't passing -O2 to gcc when we build
java-gnome'c C files?
        
        worthil ~/workspace/java-gnome $ V=1 make
        build/faster
        GCC	generated/bindings/org/gnome/gtk/GtkButton.c
        /usr/bin/gcc-4.4  -g -Wall -fPIC
        -I/usr/lib/jvm/java-6-openjdk/include
        -I/usr/lib/jvm/java-6-openjdk/include/linux
        -Wno-int-to-pointer-cast -Wno-pointer-to-int-cast
        -Werror-implicit-function-declaration -Wfatal-errors -Isrc/jni

        generated/bindings/org/gnome/gtk/GtkButton.c
        worthil ~/workspace/java-gnome $

We've got -g, should that be -ggdb -O2 instead?

Need to set that CFLAGS, I would avoid any forced optimizations in our
build file other than using CFLAGS provided.

CFLAGS, if set in a Makefile and also in users environment is overridden
by environment, right? Well, it is if you do this:

        ifndef CFLAGS
        CFLAGS=-O2
        endif

So we could have sensible intelligent defaults...?
