------- Comment #15 from vda dot linux at googlemail dot com 2007-07-23 00:03 ------- Disadvantages of enforcing 16-bytes stack alignment, continued:
* Code to align the stack is generated when we call a function, even when this function isn't going to use SSE. Which is ~90% of all functions out there. * gcc-generated SSE code will still crash if called from code compiled by older gcc on non-gcc compiler which chose to not align stack. Note that alternative approach (to align stack _in the function which needs it_) will not crash if called by code generated by old or new gcc. I like it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27537
