March 26th 2012
---------------
MICA v0.40
- contributions by Hamid Fadishei:
* append_pid config entry added by Hamid Fadishei, mainly for multiprocess binaries
* some warning messages resolved
Aug. 29th 2011
---------------
MICA v0.32
- significant code cleanup by Petr Tuma; notes:
* cleaned up some redundant NULL pointer casts
* cleaned up names of LRU stack entry references
* systematic testing of malloc return value in most of the tool code
* added warning on presence of multiple threads
* replaced sprintf with string streams
* added branch prediction hints using __builtin_expect where appropriate
- guard tracking progress in mica_progress.txt with a preprocessor flag (-DVERBOSE)
- test MICA built using the Intel C++ compiler, and document how to build it using
icpc in the README (TODO: benchmark the performance difference)
February 28th 2011
------------------
MICA v0.31
- improved config file parsing, i.e. remove dependency on order of entries
- updated README file
- describe some details regarding instruction mix
February 27th 2011
------------------
MICA v0.3
- increased flexibility of itypes analysis significantly
- instruction groups used in itypes analysis can be specified by the user now,
using a itypes.spec file; specify the filename in mica.conf using an entry like:
itypes_spec_file: <filename>
- by default, the old instruction groups are used
(except for SYSCALL, which was added to the group formely known as 'other')
- made block size in ilp, memfootprint and memreusedist flexible
- size can be set by specifying 'block_size: <power of 2>' in the mica.conf file
- default block size is 2^6 (64) bytes, which is a change compared to MICA v0.23 for ilp
- made page size in memfootprint flexible
- size can be set by specifying 'page_size: <power of 2>' in the mica.conf file
- default page size is 4096 (2^12) bytes
- possibly expensive assert statements and other sanity checks were removed
- bug fixes:
- memory read size wasn't being used 100% correctly
in ilp, memfootprint, memreusedist and stride analysis,
the size was being added to the start address of the read,
while (size-1) should be added; otherwise, e.g. for memfootprint,
we count an extra block being touched if the access is near a block boundary
- a small problem with an assert statement was fixed in memfootprint (>= 0 instead of >)
- fprintf statements were fixed for 64-bit systems
September 22th 2009
-------------------
MICA v0.23
Several people have reported small problems when MICA is being used with
recent Pin kits. This small patch release should resolve these issues.
- bug fixes:
* adjusted makefile and README according to Pin kit directory tree changes
* adjust mica_itypes.cpp to recognize both NOP and WIDENOP categories
June 13th 2008
--------------
MICA v0.22
- bug fixes in itypes:
* fixed issue with instructions in MISC category being counted double (both in 'control flow' and 'other' buckets)
(thanks to Ahmed S. Al-Zawawi for bringing my attention to this issue)
* added NOP instructions category
- adjusted README file to make meaning of different buckets in memreusedist more clear
(thanks to Kshitij Sudan for reporting this)
May 20th 2008
--------------
MICA v0.21
- removed -static from makefile, to avoid issues when linking MICA
(thanks to J. K. Rai and Ahmed S. Al-Zawawi for reporting this)
Dec. 3rd 2007
--------------
MICA v0.2:
- various bug fixes, including:
* reg: include non-full-width registers
* ilp: not all registers were included in analysis (stopped after first non-valid register)
* stride: fixed faulty use of readIndex/writeIndex in readMem/writeMem
* reset interval_ins_count for all characteristics
- added features:
* taking size of memory read/write into account
* implementation of memreusedist characteristics, useful for characterizing cache behavior
- adjusted:
* memory footprint measured for 64-byte blocks instead of 32-byte blocks (because most modern processors have 64-byte cache blocks)
* configuring MICA is done using a mica.conf configuration file instead of command line parameters
- speed:
* used InsertIfCall/InsertThenCall to make more analysis routines inlineable
* buffering for ilp implementation, which yields roughly 10% speedup
Sept. 29th 2007
---------------
Initial release: MICA v0.1
