From 387c058c8766cd9ad3ca88213afca5951b2d16bf Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Sun, 22 Aug 2004 16:27:30 +0000 Subject: [PATCH] * amd64-linux-tdep.c (amd64_linux_sigtramp_start): Change argument from CORE_ADDR to struct frame_info *. Use safe_frame_unwind_memory instead of deprecated_read_memory_nobpt.
