You'd have to check the GCC documentation to be sure, but I suspect that all
of "-fexpensive-optimizations -fomit-frame-pointer -frename-registers" are
already in effect at -O2 optimization level, so they're redundant.

Hi everybody
I noticed an inconsistency in oe-core regarding the variable: FULL_OPTIMIZATION
In bitbake.conf the variable is defined as follows:
FULL_OPTIMIZATION = "-O2 -pipe ${DEBUG_FLAGS}"
But if I look into the documentation.conf it tells me the following:
FULL_OPTIMIZATION[doc]= "The options to pass in TARGET_CFLAGS and CFLAGS when
compiling an optimized system. This variable defaults to '-fexpensive-optimizations
-fomit-frame-pointer -frename-registers -O2'."
I'm not sure if the documentation is wrong or if the default set in
bitbake.conf is incorrect.
Maybe somebody can shed some light on this.
