From 507a579c9a5e778ae737c7066df4864c5f1d2ccc Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 19 Apr 2013 15:35:21 +0000 Subject: [PATCH] -Wpointer-sign: dwarf2-frame.c: Pass unsigned variable to safe_read_uleb128. The 'bytes_read' change should be obvious. As for the other hunk, we're passing the address of the signed 'offset' to safe_read_uleb128, which expects unsigned. Fix it by passing the address of the unsigned 'utmp' instead, like already done on other spots in the file. gdb/ 2013-04-19 Pedro Alves * dwarf2-frame.c (execute_cfa_program): Make 'bytes_read' local unsigned. Pass 'tmp' to safe_read_uleb128 instead of the signed 'offset', and adjust. --- gdb/ChangeLog | 6 ++++++ gdb/dwarf2-frame.c | 6 +++--- 2 files changed, 9 insertions(+), 3 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0d2e7f39234..61fba01d70a 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +2013-04-19 Pedro Alves + + * dwarf2-frame.c (execute_cfa_program): Make 'bytes_read' local + unsigned.
