GCC Cortex-A17, "genattrtab: unknown value `alu_sreg' for `type' attribute"

Tue Nov 18 09:49:00 GMT 2014

Hi Abhisit,

CC'ing the gcc-help list as it's useful for others in the community.
GCC trunk just finished stage1 development and a large amount of 
features/patches were committed recently and as it seems that the trunk 
is broken at this point in time. I can confirm that the Cortex-A17 patch 
builds ok on top of SVN r217661.
