Subject: Related to Zynq demo:  Remove compiler warnings when configASSERT() is not defined... 
X-Git-Tag: V8.0.0~28
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=69376e2d4aa092234b74520a2a2541d8a2ce4bf3;p=freertos

Related to Zynq demo:  Remove compiler warnings when configASSERT() is not defined and set the type of the assembly functions to allow them to be called when the C code is compiled to THUMB instructions.
