Subject: [PATCH v2 2/6] Don't use sprintf_vma for CORE_ADDR
Date: Tue, 25 Feb 2020 22:22:00 -0000	[thread overview]
Message-ID: <20200225222243.8260-3-tom@tromey.com> (raw)
In-Reply-To: <20200225222243.8260-1-tom@tromey.com>

A few spots in gdb use sprintf_vma to print a CORE_ADDR.  This will
fail on a 32-bit build once CORE_ADDR is always a 64-bit type.

This patch replaces these calls with phex instead.

2020-02-25  Tom Tromey  <tom@tromey.com>

	* remote.c (remote_target::download_tracepoint)
	(remote_target::enable_tracepoint)
	(remote_target::disable_tracepoint): Use phex, not sprintf_vma.
	* breakpoint.c (print_recreate_masked_watchpoint): Use phex, not
	sprintf_vma.
