When debugging an application that is using all 16 registers of the neon processor (debugging on an
iPad Apple version gdb-1461.2) the registers q8-15 are not updated properly.
For example,
in this case, r3 contains a pointer to a float array (4 floats)
vld1.32 q1, [r3]
vld1.32 q8, [r3]
when the value is loaded into q1, the register values can be returned properly. However, when the
values are returned from q8, the are incorrect.
If I do a move from the values of q8 to q0 and then print them out, they display correctly.
This seems to suggest that gdb is having issues grabbing the proper values.
