f33ab1728b - rename symbol TOP_OF_TRANSLATED_FUNCTION to BEGIN_TRANSLATED_FUNCTION 2002-04-17 05:16:47 +00:00
Bryce Denney
2d87c60a34 - add BLUR_DYNAMIC_TRANSLATE2, which produces code that inserts the 
loop updates into the translated function so that the loop can be
  optimized.

ac8a29fb3d - use local variable for load_ptr,store_ptr, now that they exist. 
- add BLUR_DYNAMIC_TRANSLATE1, a simple code generator that writes to
  translate1.c
- add BLUR_DYNAMIC_TRANSLATE1_TEST that is (statically) linked with
  translate1.c

2a3524e2d2 - all target was causing blur-opcode to be compiled, when it shouldn't. 
I know, the makefile is a total mess but it works for now.

5605922ddc - add blur-opcode and all its variations into the Makefile 2002-04-17 02:31:58 +00:00
Bryce Denney
0995c43dd6 - make the blur look a lot more like an instruction emulator. I defined 
a tiny instruction set that can be used to implement a blur filter.
  Experiment with switch, function pointer, and a few different
  forms of "translated" code.

50231039fc - add blur_unroll_inner, which unrolls the x2 and y2 loops into 
one long statement.
- add nice comment on endifs that says what this is the end of
 2002-04-17 02:28:33 +00:00

63da4808e5 - fix bug in call to blur_func, causing us to get wrong answer 
- dump_array was dumping the input array instead of the output array.
  That didn't make for a very good regression test.
- add warning in BLUR_USE_SWITCH code since it doesn't do the same operation
  as the others.

b8cd08ac06 - rename blur-1.2-performance.gnumeric to blur-how-many-instructions.gnumeric 
- add spreadsheets for performance summary on several machines,
  analysis of cost of a function call, cost of a switch statement

45a03bf2d5 - add performance numbers for all variations of blur on my home machine 2002-04-16 18:16:58 +00:00
Bryce Denney
90af02f43a - add several more implementations of the blur function to measure 
the cost of function calls, switch statements, and function pointers.
 2002-04-16 18:16:01 +00:00

cb7f9d9c37 - add several more variations on blur.c 2002-04-16 18:15:03 +00:00
Bryce Denney
03febb4e7c - correct order of magnitude error in the function call overhead, measured 
as number of instructions.  Oops.
- add info about cost of switch statements

versus bochs

a02fe540cb - add performance measurements on different machines, and some data on 
how much a function call costs.

7cd78c3427 - compile blur.c in a few more configurations: with profiling and 
code coverage, and with a new switch called BLUR_USE_FUNCTION_CALL
 2002-04-16 16:46:46 +00:00
Bryce Denney
b6c94bebdb - add compile option to change innermost loop into a function call 
to measure function call overhead.
- always call dump fn so I can do regression test

to do with it.

ebe5f626f4 - CRTC write: only the changes of the start address, the cursor position or 
cursor size issue a screen update request
- reading an invalid CRTC register returns 0 / writing is ignored
- bit 7 of CRTC address register is always 0
- debug messages for CRTC registers updated / panics removed
- use the number of visible columns in text mode when calculating the screen
  width and the cursor position

1abec8c874 - moving DEBUG_ROMBIOS more to the top of the file (since it's sort of a configuration option and was 'well hidden' atm) 2002-04-11 20:17:03 +00:00

fb9dc34ce4 - check in raw keycodes patch, to be applied to wxWindows 2.3.2. It is 
not required to use a patched wxWindows library, but it allows us to
  do much better key mapping.  Bryce sent this patch to the wxWindows
  developers, and wxWindows 2.3.3 will include these changes.

dcc6df2f1e - fixed several instances where we had "delete array" but we needed 
"delete [] array".  This led to memory leaks.  Thanks, valgrind.

327e7742d2 - WLI separated his patch into 8 cpu support and workarounds. I checked 
in the 8 cpu support changes.  These are the workarounds.
