 HI
 
 Sorry by any inconvenience I could say. I'm a newbe here. I am the same
 person who send the referenced bug. I've been seeing some assembler
 outputs for IA-64. I have not seen any pair of 'mfi' boundles in the
 same cycle, and it had to be in many cases.
 
 I've searched in the gcc-code (hard-task). I've seen a suspicious code
 line in 'ia64.c' routine 'itanium_split_issue'. In the current version
 (7-Aug-2001 18:00 TMG) it seems there is only a F_TYPE slot permitted in
 the bundle window. I think it sould be two. 
 
 Here is the patch i proposed. I'm not sure about it.
 
 Guillermo.
