Bryce Denney 13bb61838e - add comments describing how blur-translate works 2002-04-17 22:51:58 +00:00
Bryce Denney 8dbf420ac5 - move common definitions into blur-translate.h, which is included by 
both blur-translate.c and all translated code when it is compiled.
- use DO_*() macros in blur-translate.h to implement the switch() statement
  in the emulate function, so that the same code is really used for both
  emulation and translation.

Bryce Denney 05d6a719b9 - print checksum after running each one 
- minor fix
 2002-04-17 21:30:15 +00:00
Bryce Denney 59572dcbcf - add command line args to let you choose reference implementation, 
emulation, or translation.
- allow multiple timers
- report time required to translate and compile

Bryce Denney 16ec33a673 - add blur-translate, which has a somewhat cleaned-up interface to the 
dynamic translation.  I added a structure called a CodeBlock that
  points to the instruction list, the dynamic library handle, and the
  function pointer.  To translate a CodeBlock, just call
  translate_block (block).

Bryce Denney 5fd7c60491 - add BLUR_DYNAMIC_TRANSLATE3 which generates C code, compiles it into 
a dynamic library, loads it, and runs it.  Requires libtool.
 2002-04-17 07:15:02 +00:00
Bryce Denney 8ad83d2588 - add -DBLUR_DYNAMIC_TRANSLATE3 which generates code, compiles it into 
a shared library, and then dlopens it!
 2002-04-17 07:13:55 +00:00
Bryce Denney 2c23c66580 - little script to make it easy to compile a .c file into a shared library 2002-04-17 07:07:57 +00:00
Bryce Denney 80e8d62be6 - add definitions for a new type of dyn translation 2002-04-17 05:17:14 +00:00
Bryce Denney 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.
 2002-04-17 05:15:37 +00:00
Bryce Denney da49759323 - add another dynamic translation test (#2) 2002-04-17 05:14:01 +00:00
Bryce Denney ec70461406 - finally clean up Makefile, add dynamic translation code 2002-04-17 04:21:15 +00:00
Bryce Denney 75af26d25f - auxilliary file included by translate1.c 2002-04-17 04:19:03 +00:00
Bryce Denney 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

Bryce Denney 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.
 2002-04-17 02:40:40 +00:00
Bryce Denney 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.
 2002-04-17 02:31:36 +00:00
Bryce Denney 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
Bryce Denney 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.
 2002-04-16 22:40:30 +00:00
Bryce Denney c39bd9d302 - provide speed & model of the ultrasparc 2002-04-16 20:08:32 +00:00
Bryce Denney 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
 2002-04-16 19:51:09 +00:00
Bryce Denney 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
Bryce Denney 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
 2002-04-16 17:32:55 +00:00
Bryce Denney bb0b22dca1 - gnumeric spreadsheet in which I calculated performance of native machine 
versus bochs
 2002-04-16 16:48:58 +00:00
Bryce Denney a02fe540cb - add performance measurements on different machines, and some data on 
how much a function call costs.
 2002-04-16 16:47:17 +00:00
Bryce Denney 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
 2002-04-16 16:08:18 +00:00
Bryce Denney 8d53729ed3 - add rcs version 2002-04-16 14:30:47 +00:00
Bryce Denney 8dec872375 - check in a performance test case, blur.c. See README for what I hope 
to do with it.
 2002-04-16 14:28:29 +00:00
