38** Read in ASCII from standard input
39** Expect ONE LABEL and ADDRESS in hex per line.
40** Rest of data input line is ignored so it may

42**
43** LABEL = 0 read data
44** 1 write data
45** 2 instruction fetch
46** 3 escape record (treated as unknown access type)

170** BUS RECORD format generated by output option 2 or 3 (-o2 or -o3)
171** used by packbus.c and other programs (ascii, all numbers in hex).
172**
173** BUS2 Access Size Address Rcount Icount
174**
175** where:
176**
177** BUS2 is a literal character string; all lines that do not
178** start with BUS2 are ignored.
179**
180** Access is a access code (r==BUSREAD, w==BUSWRITE, p==BUSPREFETCH,
181** and s==BUSSNOOP (-o3 only)).
182**
183** In COPYBACK, misses can cause dirty blocks to be written
184** back. When this happens, a bus read followed by a bus
185** write is reported (as if the cache has write buffers).
186** The bus write follows the bus read with a Rcount and
187** an Icount of 0.
188**
189** Address (hex) is address of bus transfer (0 <= Address <= 0xffffffff).
190**
191** Size (deciaml) is the transfer size in bytes.
192**
193** Rcount (decimal) is count of all references since the last miss
194** including the current reference. E.g., the second of
195** two consecutive misses will have an Rcount of 1.
196**
197** Icount (decimal) is count of instruction fetches since the last miss
198** including the current reference. E.g., the second of
199** two consecutive instruction fetch misses will have an
200** Icount of 1.

319Porting Information:
320
321DineroIII runs on Unix 4.2 BSD systems. I have used it on the
322VAX and SUN-1 architectures. DineroIII runs with some modifications
323on CMS system with the Waterloo CMS/VM C Compiler. Setting "IBM370"
324and resetting "NOTIBM370" in file global.h will cause "ifdef's" to
325make changes necessary for CMS/VM port.
326
327DineroIII uses a fast C-function called "sscanxx" to interpret
328input characters instead of the library function "sscanf"
329because a profile showed that dineroIII was spending 35% to 50%
330of this time in sscanf. The function "sscanxx" runs about 6
331times faster than "sscanf." The function "sscanxx" is selected
332by the compile-time flag FAST_BUT_DANGEROUS_INPUT in global.h.
333DineroIII with sscanxx should run in 60 to 70% of the time of
334dineroIII with sscanf.
