1. create asm listing:
|
||
|
|
compile .o only, then use objdump
|
||
|
|
kos32-tcc.exe -c -g clipview.c -o clipviewtcc.o
|
||
|
|
kos32-objdump -d -M intel -S -l clipviewtcc.o > clipviewtcc.asm
|
||
|
|
|
||
|
|
2. see offset in resulting kolibri executable compared to listing (i have 0xD0)
|
||
|
|
|
||
|
|
3. in kolibri debugger mtdbg set breakpoint to funtion address
|
||
|
|
>bp 140
|
||
|
|
where 0x140 is 0x70 in assemly + offset 0xD0
|
||

Warning !!Error. sometimes tcc dont warn about unsuccesful linking
|

(not found function body code). Hopefully, i fix this.

Usually, at runtime you have crash with "Illegal cpu instruction"
|
||
|
|
In assembler code this is easy to recognize as
|
||
|
|
myaddr:E8 FC FF FF FF call myaddr+1
|
||
|
|
|
||
|
|
4.how to see defines
|
||
|
|
kos32-tcc.exe -E -dD null
|
||
|
|
|
||
|
|
5.if you use GNU LD as a linker, add option -Map=hellocpp.map to ld.
|
||
|
|
Mtdbg can use resulting .map file
|
||
|
|
|
||
|
|
6.now you can use -g option to generate .dbg file. This enables
|
||
|
|
source code level debugging with Mtdbg
