It's another issue with SRA and -Os. With an old 4.1, I have:
$ ./xgcc -c -Os -B. btst.c && size btst.o
text data bss dec hex filename
5339 0 0 5339 14db btst.o
$ ./xgcc -c -Os -fno-tree-sra -B. btst.c && size btst.o
text data bss dec hex filename
224 0 0 224 e0 btst.o
So we're actually better than 3.3, after we disable -ftree-sra. I guess SRA
should be tuned (disabled?) for -Os.
Please, do file a bugreport.
