2010-10-08	1. refactoring cuda api code for loading PTX (removing external PTX loading ↵	Tor Aamodt
	entirely) 2. some bug fixes for warp_inst_t 3. creating a new class, gpgpu_t, which contains the functional "memory" state visible to all threads running on a GPU (doing this as part of my continuing effort to hunt down and eradicate every global variable that is not the top level "the gpu") 4. other misc. changes Almost passing CUDA 3.1 regression? oclHistogram keeps failing under torque, but does not fail when run on the command line from the same directory. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7827]
2010-10-05	broken change list: builds, but does not run, yet	Tor Aamodt
	refactoring: create warp_inst_t that provides notion of a group of scalar instructions traveling down the pipeline. delete DWF delete MIMD delete warp_tracker delete old writeback stage, replace it with a stub that just writes back everything delete old pipeline model current status: MSHR's need to change to deal with the new structure [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7814]
2010-10-01	integrating recent changes from fermi-test into fermi	Tor Aamodt
	(i'll use "fermi" for more disruptive changes to the pipeline model such as updating the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7805]
2010-08-30	integrating CL 7421-7434 from fermi-test	Tor Aamodt
	this integrates the ptxplus functional model changes, but has only been verified with CUDA 3.1 PTX regressions (which pass) still need to verify ptxplus itself is working in this branch [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7435]
2010-08-23	- add '-keep' option to keep intermediate files (used for OpenCL only right now)	Tor Aamodt
	- remove redundant initialization code of options (which confuses new users) - make bool option variables bool type - remove some more extern decls [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7247]
2010-08-08	check if debug thread selected	Tor Aamodt
	[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7163]
2010-08-08	add listing function for ptx debugging	Tor Aamodt
	print out compilation errors encountered during OpenCL to PTX conversion (still a bit cryptic) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7162]
2010-08-07	watchpoint facility for ptx debugging	Tor Aamodt
	[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7160]
