actually that did not add it, it was there before that patch, just moved it to the function. The comment above DATA_ALIGNMENT in i386.h should explain why it was this is done: One use of this macro is to increase alignment of medium-size data to make it all fit in fewer cache lines. Another is to cause character arrays to be word-aligned so that `strcpy' calls that copy constants to character arrays can be done inline. */ Though this should be moved to i386.c so this question no longer is there. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22158
