Update to new compiler version, recompile all libraries and test #100

Closed sy2002 closed 4 years ago

sy2002 commented 4 years ago

Update and recompile the compiler

  1. Merge the branch develop into dev-vga-colour. Reason: The newest commits of develop are storing our specific improvements and fixes of the compiler backend (including the bugfixes for clearing the X and C flags that lead to the nasty arithmetic errors) in a separate folder: c/qnice/compiler-backend/. This makes sure, that we are not loosing our newest compiler backend code, when applying a patch from Volker's main repository. Also, the develop branch contains updated make files that make use of these changes.

  2. Get the newest snapshot of VBCC and copy it to c/vbcc

  3. Run tools/make-toolchain.sh. This makes sure, that monitor/compile_and_distribute.sh is automatically being run first, which is important for having the newest sysdef.h in compiler-backend. From there, the new compiler backend is automatically copied into the VBCC folder.

Recompile the libraries

  1. Go to the c folder and enter source setenv.source

  2. First run make-qnice-monitor-lib.sh, because the standard c library depends on it

  3. Then make sure that you have copied the source code into vclib

  4. Then run make-vclib.sh

Recompile /qbin and test

  1. Run /qbin/make.sh

  2. Test what can be tested in the emulator

  3. Test on hardware

  4. At least also test c/test_programs/arith.c and your bug-test-c files to make sure, all our bugfixes made it to the final result

There is an updated version of the documentation of how to update the compiler: Use this one:

https://github.com/sy2002/QNICE-FPGA/blob/develop/doc/vbcc.md#updating-to-newer-compiler-versions

sy2002 commented 4 years ago

I updated to the newest VBCC: While doing so, I discovered, that my compile script had a bug and that the documentation was also not precise enough when it comes to keeping the old config and targets folder. Fixed that, see: https://github.com/sy2002/QNICE-FPGA/blob/develop/doc/vbcc.md#update-and-recompile-the-compiler

Then I did a very superficial smoke test: Only on the emulator, not on hardware.

Assigning to @MJoergen Please test on hardware, before closing this issue.

Here are the results of my smoke test (I tested the /qbin apps that are made with C):

App Result Comment
adventure.out ✅
demo_atom.out ✅
demo_sprite_balls.out ✅
demo_tree.out :x: Looks weird, see issue #151
hdmi_de.out :x: Not supposed to work in current emulator version. Possibly deprecated due to new VGA
maze2d.out :x:  Stops after maze has been generated, see issue #152
shell.out ✅
sierpinski.out ✅
ttt2.out ✅
vga_calibration.out ✅
wolfram.out ✅
world.out ✅

After @MJoergen added the VBCC bugfix, I recompiled the monitor lib, the compiler's standard C lib and /qbin. Still left as TODO is at least a smoke test like https://github.com/sy2002/QNICE-FPGA/issues/100#issuecomment-703107614 on emu and hardware needs to happen.

MJoergen commented 4 years ago

Following is tested on hardware:

hdmi_de is deprecated due to new VGA

Closing this issue now.
