Tyler J. Stachecki b7bf8be66d Forgot a keyword in an older commit. 2016-01-30 15:42:38 -05:00
Tyler J. Stachecki 2b5eaa579d Try to reduce VR4300 cycle overhead as well. 2016-01-30 14:58:31 -05:00
Derek "Turtle" Roe 8b89df2fdc See long description 
Replaced all references to simulation with emulation
Updated copyright year
Updated .gitignore to reduce chances of random files being uploaded to
the repo
Added .gitattributes to normalize all text files, and to ignore binary
files (which includes the logo and the NEC PDF)

Tyler Stachecki 369d33c2d1 Windows fixes as reported by magumagu. 2014-12-07 10:40:42 -05:00
Tyler Stachecki c1dc7cba08 Refactor for another major performance boost. 
Since the CEN64 core now runs in it's own thread (and doesn't use
the FPU), we can steal the host's FPU state register and not have
to worry about preserving it.

Along with that major overhaul, don't force "extra" features like
simulation statistics and debugging if the user doesn't want them.
Including that code, even when it is not run, mucks with register
allocation or something ever so slightly.

Tyler Stachecki 31443e65c5 Mark another function as cen64_cold. 2014-11-14 22:22:00 -05:00
Tyler Stachecki 85654a891f Delay computing accurate value of count. 
Instead, just bump the counter and don't track cycle count. When
it comes time to use count, shift it to the right by one instead.

Tyler Stachecki e89f054674 Optimize extremely aggressively. 
Tell GCC to optimize cold functions for size and stash them away in
a separate part of the binary. Put the simulate core, meanwhile, on
the hot path. Also, bump optimization to -O3 as we can now "afford"
to do so.

Tyler Stachecki d45cab877a Add a -printsimstats switch. 
Start working in a "extra" mode for debugging and other features
that we don't want on the main path. As a demonstration of what we
can do with this extra mode, print out a bunch of simulation info
that can help us optimize offline.

Tyler Stachecki e6bc8ebe64 Add more TLB support, verify things. 2014-08-23 20:06:45 -04:00
Tyler Stachecki 5f5d4da9a6 Commit preliminary (untested) TLB support. 2014-08-23 14:24:21 -04:00
Tyler Stachecki bf46aa1fb3 Reorganize structures. 
If we place larger, less commonly used structures after our
frequently accessed state variables, the average size of x86
instructions will be reduced due to the smaller offsets off
the base pointer.
