Synopsis: SSE mis-alignment with -O0
State-Changed-From-To: open->analyzed
State-Changed-By: hubicka
State-Changed-When: Sat May 18 14:07:27 2002
State-Changed-Why:
This is well known problem of the main function. GCC aligns stack dynamically for functions called from main, but not for main itself. Runtimes needs to be fixed to get the alignment right or GCC needs to be extended to support dynamic frame alignment.
