|
|
here are the diffs, apply against 0.2.4... um, not sure how to do multi-file diffs, so there are 5 files here; note that dll.exe needs to be rebuilt to handle the changed parity... still looking in the kernel for a clean place to stick in timeout (...)

| | Can now use gcc 2.95.2 for legOS
|
|
Hi all. Well, I finally got around to checking out the problem with compiling legos with gcc 2.95.2. And the good news is, it's not a bug with gcc!! The problem is the in-line assembly in memcpy.c (also in memset.c). If you apply the patch at (URL) (...) (24 years ago, 18-Jul-00, to lugnet.robotics.rcx)

(...) legOS 0.2.3 or 0.2.4 will load .strings and .rodata sections just like the .text section. With this you can achive persistent data by storing your variables into the .strings section. There are some nice features in gcc to help with this. Just (...) (24 years ago, 16-Jul-00, to lugnet.robotics.rcx.legos)

(...) It is correct. Everytime you reload a program it re-initializes everything, including a specific program's memory, so all that kind of information is lost.

Mike- I wish I knew. I have frequently seen the same kinds of "random" changes produce better results. For example, I had one piece of code that used a switch statement- 19 statements in all. I added a 20th and poof... it froze. I have no idea what (...) (24 years ago, 14-Jul-00, to lugnet.robotics.rcx.legos)

I had a strange experience today. My program likes to crash a lot. I accept this as a fact of life now; part of it is the difficulty in debugging it, and part seems to be the beta-ness of legOS. However, today, I tracked down one particularly evil (...) (24 years ago, 14-Jul-00, to lugnet.robotics.rcx.legos)
