I just hit this while trying to get the u-boot SPL (bootstrap loader, which must fit in internal SoC SRAM) down in size, so it would be great to see a fix for this. Regards, Hans

I post a question on StackOverflow : http://stackoverflow.com/questions/26100976/var-declare-inside-a-printf-cant-be-garbage-collected-by-gcc?answertab=oldest#tab-top And i sent a message on GCC-Help mailing list : https://gcc.gnu.org/ml/gcc-help/2014-10/msg0.html It's really annoying when you try to optimize the size of the executable. Thanks
