#8657 closed enhancement (wontfix)

I noticed for some archs (such as atheros [20335] and ppc44x [16900]), CONFIG_CC_OPTIMIZE_FOR_SIZE=y. But by default, CONFIG_CC_OPTIMIZE_FOR_SIZE is not set.

Perhaps it should be enabled by default?

Not sure if it is the case here but on some/arch toolchain combination the size optimize actually makes the image bigger as there's less redundant code to compress.

  • Resolution set to wontfix
  • Status changed from new to closed

That option is intentionally disabled for performance reasons. The cflags have been altered to get the size as close as possible to what you get with CONFIG_CC_OPTIMIZE_FOR_SIZE enabled.
