Code based breakpoints using ca65 and VICE
Recent discussions about debugging etc made me do this, much like Doynax's stuff:
Macro for ca65:
.macro breakpoint name
.ident (.concat("br_", .string(name))):
.export .ident(.concat("br_", .string(name)))
.endmacro
Link line in your Makefile:
ca65 -C link -m map -Ln symbols $(OBJS) && sed 's/al [0-9A-F]* \.br_\([a-z]*\)/\0\nbreak \.br_\1/' < symbols > symbols2
Basically it tells ca65 to emit all labels into a file called symbols. The sed-script then locates all symbols starting with br_ and adds a breakpoint command after it.
To run in VICE:
x64 -moncommands symbols2 whateva.d64
This enables you to add breakpoints directly into your sourcecode like:
breakpoint flashcolors
inc $d020
jmp *-3
Have fun with future debugging! :)

DGGR: Exactly. Good to see you found the solution. Im not checking csdb that often anymore, but I just started this little facebook group , so feel free to join https://www.facebook.com/groups/RetroAssembler/ and discuss any retro assembler. There you will get a quick answer. Once I get time to make new releases it will be announced there as well.
Edit : Btw Everybody is welcome |

"Also, i wonder how we survived in the past? :-)"
it sucked.
I remember having turn disk bug in Void while linking on a stock machine.
We spent a whole afternoon with Edhellon with this:
- load turbo ass
- load source
- change something
- save object
- load binary
- load object
- save them in one file to demo linking disk
- watch fuckin whole first side
- discover turn disk is still buggy
- goto 10
yeah, and in the end it turned out that I have deleted the turn disk routines from the binarily ripped loader, because I had no idea they are there for that :) |

thats your own fault though, loaders for side 2 could be done in 1997 too (just like part selectors) :) |

that wouldnt make auto disk side change detection work tho. anyway after like the 8th time we tried the loader alone, instead of watching the whole side 1, to speed things up :) |

no, but you could have tested only the last part of side 1 and the disk changing :) (you cant imagine how often i did that for artphosis.... argl) |

it comes back as we talk about it, things was we tested the loader seperately aswell, but that test case used a loader with disk change routines included, which was missing in the demo :P :) |

And how would breakpoints have helped with this pebcak-situation? :-P |

well, warpmode and modern cross asm env would have sped up the process a lot :) |
