From 17547186c25aa96d078a6ff9d61a55880fa009f4 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 4 Mar 2019 12:05:47 -0700 Subject: [PATCH] Make null_ptid and minus_one_ptid "const" This makes null_ptid and minus_one_ptid "const". I think this is an improvement because it means they can't be accidentally modified. 2019-03-12 Tom Tromey * common/ptid.c (null_ptid, minus_one_ptid): Now const. * common/ptid.h (null_ptid, minus_one_ptid): Now const. --- gdb/ChangeLog | 5 +++++ gdb/common/ptid.c | 4 ++-- gdb/common/ptid.h | 4 ++-- 3 files changed, 9 insertions(+), 4 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5e9beb9b7a..e6903f2281 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2019-03-12 Tom Tromey + + * common/ptid.c (null_ptid, minus_one_ptid): Now const. + * common/ptid.h (null_ptid, minus_one_ptid): Now const. + 2019-03-12 Tom Tromey * linux-nat.c (iterate_over_lwps): Update. diff --git a/gdb/common/ptid.c b/gdb/common/ptid.c index 93f853af80..c025511a37 100644 --- a/gdb/common/ptid.c +++ b/gdb/common/ptid.c @@ -22,5 +22,5 @@ /* See ptid.h for these. */ -ptid_t null_ptid = ptid_t::make_null (); -ptid_t minus_one_ptid = ptid_t::make_minus_one (); +ptid_t const null_ptid = ptid_t::make_null (); +ptid_t const minus_one_ptid = ptid_t::make_minus_one (); diff --git a/gdb/common/ptid.h b/gdb/common/ptid.h index 31440c8d7c..f5625a6138 100644 --- a/gdb/common/ptid.h +++ b/gdb/common/ptid.h @@ -145,11 +145,11 @@ private: /* The null or zero ptid, often used to indicate no process. */ -extern ptid_t null_ptid; +extern const ptid_t null_ptid; /* The (-1,0,0) ptid, often used to indicate either an error condition or a "don't care" condition, i.e, "run all threads." */ -extern ptid_t minus_one_ptid; +extern const ptid_t minus_one_ptid; #endif /* COMMON_PTID_H */ -- 2.34.1
