<p><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">Please let me know how to
check the hardware support of XN/XI bit support on ARM/MIPS platform.</span></p>
<p><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">As there is support of XN
bit on ARM v >= 6 (I was using ARM 6), but no support on MIPS (</span><b><span style lang="EN-US">MIPS 34Kc)</span></b><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">.</span></p>
<p><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">To check the hardware
support , I run the paxtest i.e execstack. The execstack test program must
crash on ARM, but not on MIPS.</span></p>
<p><b><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">But It is crashing on both ARM and MIPS.</span></b></p>
<p><span style="font-size:9pt;line-height:115%;font-family:"Arial","sans-serif"">Please let me know how I can
prove/check the hardware support of XN bit in arm platform.</span></p>
