From 74b773fcd658c52554a6af07c657f677c52f8102 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Fri, 11 Dec 2020 13:48:11 -0500 Subject: [PATCH] gdb: factor out debug_prefixed_printf_cond The same pattern happens often to define a "debug_printf" macro: #define displaced_debug_printf(fmt, ...) \ do \ { \ if (debug_displaced) \ debug_prefixed_printf ("displaced", __func__, fmt, ##__VA_ARGS__); \ } \ while (0) Move this pattern behind a helper macro, debug_prefixed_printf_cond and update the existing macros to use it. gdb/ChangeLog: * displaced-stepping.h (displaced_debug_printf): Use debug_prefixed_printf_cond. * dwarf2/read.c (dwarf_read_debug_printf): Likewise. (dwarf_read_debug_printf_v): Likewise. * infrun.h (infrun_debug_printf): Likewise. * linux-nat.c (linux_nat_debug_printf): Likewise. gdbsupport/ChangeLog: * common-debug.h (debug_prefixed_printf_cond): New. * event-loop.h (event_loop_debug_printf): Use debug_prefixed_printf_cond.
