More support for setup environment
1. More general solution to get CC_VERSION, work for Linux(OpenSUSE, Ubuntu,
Debian) and OSX
2. Add zsh support, change == to = to make it compatible with bash, zsh and sh
3. Fix a bug in Makefile

Integrating CLs up to 15295. Descriptions of these CL's are included.
***
A couple changes to aeriel-vision for warp issue plot support
***
More arielvision changes to support the variable-entry length stacked bar chart
***
Properly printing the right resolution of dynamic warp ids
***.
Generalized the scheduler code and added detailed statistics for which warps issue each cycle.
Verified the execution of the LRR scheduler - still have to get the two level scheduler to work.
***
Implementing the 2lvl scehduler has it has been originally coded.
LRR on both the inner and outer levels
***
Adding in a debug tracing system to GPGPU-Sim.
I am sick of writing debug code - then having to comment out, ifdef out or delete it to checkin.
This also allows for print streams so the user can decided which traces they would like to see.
Every print in GPGPU-Sim should go through this system - then it will be really easy to only get the information you want and more importantly people will (a) write and (b) checkin code that actually profiles what they are building.
Reading tracefiles is superiour in many ways to single stepping since you can print the world and just vet the logfile for what you need.
This also fascilitates advice from the Debugging Rules! book which states that you should never throw away a debugging tool. Having debug prints that don't get thrown away is big.
***
Allowing the trace to be specified in the Make.
Run Make TRACE=0 to compile the code without any traces
***
Allowing prints from the performance sim to get the actual ptx instruction text
***
Getting the two level scheduler to actaully work...
What is released in fermi does not work at all - it effectively performs "static warp limit" from my CCWS paper.
Warps are never demoted from the active list since the functionality checking to see if they are waiting on a longop is completly broken.
Maybe if the original author had access to the tracing functions this would not have happened.
The islongop test was completely broken. It did not mark the register as used, it marked the register number in the instruction as used.
For example if this instruction was creating a long op:
ld r6 [r1]
It would mark register 0 as waiting for a long op (since it is register 0 of the two registers in this instruction), not register 6.
Additionally, whenever ANY instruction from a warp releases registers, ALL the longops being tracked for this warp get cleared....
The only way anyone ever thought this worked is if they did not test it....
***
Reworking the warp schedulers to share common code.
Making the GTX480 use gto by default. I am not sure wht they really use, but it really can't be LRR.
Also adding in a new file for custom shared trace defines. These are useful when you want a print that has some
additional criteria or information printed.
Verified that the schedulers all work to a first order based on traces.
***
Making it so you can run the stats collection scripts from any directory.
Also allow the caller to specify a stats file instead of just assume its always the same one

replaced this with defining an empty class if #GPGPUSIM_POWER_MODEL is not defined.
2- fixing the makefile to make it actually compiles if the #GPGPUSIM_POWER_MODEL is not defined.

- ptxplus ... edits to eliminate some warnings with older gcc about printfs without string literal
- eliminate warning about map (just too annoying while testing on Mac)

imply user should bugger off and stop asking developer for help)
- Remove ridiculously long and cryptic comment from setup_environment. Most people will use CUDA_INSTALL_PATH.
- Remove decuda targets from Makefile
- Add check to Makefile to insist that setup_environment was run first
- Add version file (eliminate redundancy) and remove version strings from src/cuda-sim/cuda-sim.cc

cubojdump.l/.y are used to parse the output of cuobjdump, and thus should be part of libcuda not cuobjdump_to_ptxplus
Included are also modifications to Makefiles

Stopping if someone tries to use PTXPlus without cuobjdump
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12138]

1. Adds support for using cuobjdump for both ptx and ptxplus execution. This has been tested with CUDA 4.0
. Ptxplus is no longer supported through decuda/decuda_to_ptxplus
2. Adds support for converting the SASS output by cuobjdump to ptxplus. This has been tested with CUDA 4.0
. The old path that extracts ptx from cubin files is still preserved
3. Adds a bank group model. (WARNING: memory config has changed, please adapt yours). To disable the bank groups model, set nbkgrp to 1 and tCCDL and tRTPL to 0
Diff the configuration files to learn about how to use those new options.

Now, you have to define both NVOPENCL_LIBDIR and NVOPENCL_INCDIR in the setupd_environment script to build with opencl. If any of them is not setup, gpgpu-sim will build will output a warning and built without opencl support.

that info.
"make docs" to build and "make cleandocs" to clean. You have to have doxygen and graphviz installed.
The new docs target doesn't build with the simulator (you have to call it explicitly) to avoid giving unecessary errors to people.

for multiple configs of the built simulator to exist at one time. Now you no longer have to clean build when changing from debug to release configs it also eliminates the possibility of having a fraken-file where some objects are in debug and some are in release.

- read only cache model with integrated mshrs (no L1D, yet); new
cache interface should be easily extendable to support texture
cache with latency fifo and separate tag/data arrays, though
this is not yet added (currently tags and data arrays are not
decoupled for texture)
- new partition model using the above
removes all old MSHRs, L1D etc...
passing CUDA 3.1 regression

as updating the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...)

is installed for math intrinsics used in instructions.cc (since
CUDA 3.1 does not seem to define __uint2float).
- currently cuda-math.h has hardcoded paths to my own install of
CUDA 2.3 (need to determine whether we can build simulator with
CUDA 2.3 and run CUDA 3.1 / compute_2x PTX, or need to make
current setup more portable)
- modified ptxinfo.l to print out meaningful error message if
error occurs on first line
- modified ptxinfo.l,y to understand "for 'compute_NN'" syntax
- updated template to 3.1 SDK version
- updated cuda_runtime_api.cc to select highest compute capability
version when multiple versions are present.
- updated template/BlackScholes Makefiles to generate a "DLL build"
instead of static linked build (still confusing... requires one to
copy config files... probably need to modify config scripts)
