Re: Debugging pthread in ARM.

[gomrioje <gomez.j@ikusi.es>]

I have tried, and I get the same result.

Could it be link to:
http://sources.redhat.com/ml/gdb/2003-06/msg00535.html ?

It was about single-step in gdbserver for pthread_create?

	* linux-arm-low.c (arm_reinsert_addr): New function.
	(the_low_target): Add arm_reinsert_addr.
