To help users generate a valid data.pcl file. Compile as
$FC -I$PCLINC -DUSE_PCL pcl_events.F -o pcl_events -L$PCLLIB -lpcl $OTHER_LIBS
where $OTHER_LIBS would be -lperfctr (on Linux/x86) or -lcpc (on SunOS) 
depending on what other libraries PCL depends on. 

Run in the same directory as a candidate data.pcl. Correct lines as suggested.

If compiled without the -DUSE_PCL define flag it will simply inform the user 
of which PCL rate events can be measured concurrently, starting with Mflop/s.

Please note that PCL events are always specified as their numeric value:

0  PCL_L1CACHE_READ
1  PCL_L1CACHE_WRITE
2  PCL_L1CACHE_READWRITE
3  PCL_L1CACHE_HIT
4  PCL_L1CACHE_MISS
5  PCL_L1DCACHE_READ
6  PCL_L1DCACHE_WRITE
7  PCL_L1DCACHE_READWRITE
8  PCL_L1DCACHE_HIT
9  PCL_L1DCACHE_MISS
10 PCL_L1ICACHE_READ
11 PCL_L1ICACHE_WRITE
12 PCL_L1ICACHE_READWRITE
13 PCL_L1ICACHE_HIT
14 PCL_L1ICACHE_MISS
15 PCL_L2CACHE_READ
16 PCL_L2CACHE_WRITE
17 PCL_L2CACHE_READWRITE
18 PCL_L2CACHE_HIT
19 PCL_L2CACHE_MISS
20 PCL_L2DCACHE_READ
21 PCL_L2DCACHE_WRITE
22 PCL_L2DCACHE_READWRITE
23 PCL_L2DCACHE_HIT
24 PCL_L2DCACHE_MISS
25 PCL_L2ICACHE_READ
26 PCL_L2ICACHE_WRITE
27 PCL_L2ICACHE_READWRITE
28 PCL_L2ICACHE_HIT
29 PCL_L2ICACHE_MISS
30 PCL_TLB_HIT
31 PCL_TLB_MISS
32 PCL_ITLB_HIT
33 PCL_ITLB_MISS
34 PCL_DTLB_HIT
35 PCL_DTLB_MISS
36 PCL_CYCLES
37 PCL_ELAPSED_CYCLES
38 PCL_INTEGER_INSTR
39 PCL_FP_INSTR
40 PCL_LOAD_INSTR
41 PCL_STORE_INSTR
42 PCL_LOADSTORE_INSTR
43 PCL_INSTR
44 PCL_JUMP_SUCCESS
45 PCL_JUMP_UNSUCCESS
46 PCL_JUMP
47 PCL_ATOMIC_SUCCESS
48 PCL_ATOMIC_UNSUCCESS
49 PCL_ATOMIC
50 PCL_STALL_INTEGER
51 PCL_STALL_FP
52 PCL_STALL_JUMP
53 PCL_STALL_LOAD
54 PCL_STALL_STORE
55 PCL_STALL

and the last 5 ("rate events") cannot be used when "-pcl" is used in genmake2:

56 PCL_MFLOPS
57 PCL_IPC
58 PCL_L1DCACHE_MISSRATE
59 PCL_L2DCACHE_MISSRATE
60 PCL_MEM_FP_RATIO
