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

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

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

90af02f43a - add several more implementations of the blur function to measure 
the cost of function calls, switch statements, and function pointers.

03febb4e7c - correct order of magnitude error in the function call overhead, measured 
as number of instructions.  Oops.
- add info about cost of switch statements

bb0b22dca1 - gnumeric spreadsheet in which I calculated performance of native machine 
versus bochs
 2002-04-16 16:48:58 +00:00

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

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

8dec872375 - check in a performance test case, blur.c. See README for what I hope 
to do with it.
