on ia-64, I see the following (2.4.18, with gcc3.1):
- ext2_follow_link(): 16 bytes/frame - vfs_follow_link(): 56 bytes/frame - link_path_walk(): 128 bytes/frame --------------------- --------------- total: 200 bytes/frame Just about in line with what you'd expect given that registers are 64 bits.
On sparc64 the situation is much worse (due to register windows) which means any non-leaf function (function which invokes no nother functions) equals 192 bytes of stack space per frame minimum.
