Maybe it's a stupid question, but... is there a way to hard-code a breakpoint ? I need to check a bit of code that gets called too many times and I'd like to put a conditional breakpoints compiled in code; no way to use winedbg built-in conditional breaks, the condition is too complicated.....
You can do:
if (complex condition) { _CrtDbgBreak(); }
Or equivalently: if (complex condition) { __asm__ ("\tint $0x3\n"); }
The int 3 is a software breakpoint (or rather, a software breakpoint is an int 3). The bove code will cause you to drop in the debugger if the int 3 ever gets executed. This only works on x86 architectures but this is probably all you need.
