commit 284c0820e4717aa2b7a34a9073a4d5a132f1536a
Author: Stephane Eranian <er...@gm...>
Date:   Thu Jun 2 12:49:25 2011 +0200

    reduce size of AMD64 event tables
    
    Use the same technic as for Intel X86,
    go from:
    
    struct entry_t {
    	int numasks;
    	umask_t umasks[MAX];
    };
    
    to:
    
    umask_t foo[]= {
    };
    
    struct entry_t {
    	int numasks;
    	umask_t *umasks = foo;
    
    };
    
    Size reduction is also important, from:
       text	   data	    bss	    dec	    hex	filename
      15128	    192	      0	  15320	   3bd8	pfmlib_amd64_k7.o
      59109	   1152	      0	  60261	   eb65	pfmlib_amd64_k8.o
      87197	    576	      0	  87773	  156dd	pfmlib_amd64_fam10h.o
      56737	    192	      0	  56929	   de61	pfmlib_amd64_fam14h.o
    
    to:
       text	   data	    bss	    dec	    hex	filename
       3412	    192	      0	   3604	    e14	pfmlib_amd64_k7.o (ex lib/libpfm.a)
      19961	   1152	      0	  21113	   5279	pfmlib_amd64_k8.o (ex lib/libpfm.a)
      33665	    576	      0	  34241	   85c1	pfmlib_amd64_fam10h.o (ex lib/libpfm.a)
      21909	    192	      0	  22101	   5655	pfmlib_amd64_fam14h.o (ex lib/libpfm.a)
    
    Overall: 37% size reduction. This is less than on Intel X86, but the umasks
    array was only 16-entry long and most events had 4 or more umasks.

commit 7e8541d287c8e1fad11f249406f5fe686339dfe2
Author: Stephane Eranian <er...@gm...>

    pfm_get_event_attr_info() returns ucode >> 8
    
    pfm_get_event_attr_info() returns the attribute (umask)
    code and not the raw code which is now shifted by 8, i.e.,
    final position in register. This make more sense and provides
    backward compatibility. offcore_response umasks are treated
    differently, the raw umask code is never shifted << 8.
