From 0e90f49b112e4c91dee7d61eccc06bcd25b9c534 Mon Sep 17 00:00:00 2001 From: Franck Bui-Huu Date: Fri, 29 Sep 2006 11:08:59 +0200 Subject: [PATCH] [MIPS] Let gcc align 'struct pt_regs' on 8 bytes boundary The stack pointer in MIPS/gcc should always 8 bytes aligned on entry to any routines. Therefore pt_regs structure must be aligned to 8-byte boundary too. Instead of creating dummy fields to achieve this alignment, this patch let gcc doing it. Therefore 'smtc_pad' field can be safely removed.
