20140921 - Using GDB Without Source and With Runtime Changing of Code
+
+
+Getting disassembly of code generated at runtime to verify dynamic code generation can be a slow process.
+On Linux, I just use gdb.
+Using gdb requires setting the breakpoint for run-time generated code
+after that code is generated by the application
+(if there is an easier way, I don't know it).
+Here is a quick example,
+
+
+Find the entry point of the ELF: readelf -a filename
+Look for "Entry point address:" and write down address
+Start gdb: gdb filename
+Insert breakpoint, this example using 0x2c3 as entry point: break *0x2c3
+Start program which will break at above entry point: run
+Show disassembly with raw bytes example: disassemble /r 0x2c3,0x300
+The "=>" shows the instruction pointer
+Set another breakpoint to something after run-time generated code
+Use the "continue" command to continue to that breakpoint
+Show disassembly of the run-time generated code
+
