I am encouraged by some of the generated code I have reviewed. I like what it

I am a little lost with the difference between LIBRARY_OPTIMIZATION_FLAGS and
OPTIMIZATION_FLAGS? RTEMS is always a library so what is difference between
them? Are the OPTIMIZATION_FLAGS the "-O" ones and still something I can set
from an INI file?
Currently the OPTIMIZATION_FLAGS are used for all code (code for libraries and
code for tests). With this change you can build the libraries with -O0 and the
tests with -O2 for example.
Oh so if I understand this the LIBRARY_OPTIMIZATION_FLAGS are per library?
Not per library, the LIBRARY_OPTIMIZATION_FLAGS are used for all libraries in
bsps and cpukit.
Is LIBRARY_OPTIMIZATION_FLAGS then a good choice? Would more direct naming like
BSP_OPTIMIZATION_FLAGS and CPUKIT_OPTIMIZATION_FLAGS be better? If this was in
the patch I would have understood exactly what they do.
The BSP is just a library: librtemsbsp.a. I can split
LIBRARY_OPTIMIZATION_FLAGS into BSP_OPTIMIZATION_FLAGS and
CPUKIT_OPTIMIZATION_FLAGS if this helps.
