Elide the need to re-read ECR in Trap handler by ensuring that
EXCEPTION_PROLOGUE does that at the very end just before returning
to Trap handler

ARCv2 EXCEPTION_PROLOGUE already did that, so same for ARcompact and the
common trap handler adjusted to use cached ECR

ARC: entry.S: Ensure that restore_regs is local to compilation unit 2015-06-19T12:39:37+00:00 Vineet Gupta vgupta@synopsys.com 2014-10-13T14:19:00+00:00 c10d6969b0958e151c9dd6cfae70ce8db9db3c7e This fixes the possible link/relo errors, since restore_regs will be provided by ISA code, but called from ARC common code. The .L prefix reassures binutils that it will be in same compilation unit. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
