From: Simon Marchi Date: Thu, 21 Jan 2021 19:12:22 +0000 (-0500) Subject: gdb: convert auto-load to new-style debug macros X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a59902a7c123512681bddc3fa90f271d4f089c35;p=binutils-gdb.git gdb: convert auto-load to new-style debug macros Function file_is_auto_load_safe was taking a format string and varargs just to output a debug print. This is probably because that function is used in linux-thread-db.c and main.c, but debug_auto_load is static in auto-load.c. I simplified that, making debug_auto_load visible outside of auto-load.c, and making the callers of file_is_auto_load_safe output the debug print themselves. This file uses _() for internationalization of the debug messages. This is not necessary, as these are mostly messages for GDB developers, and it's not used in other files anyway. So I removed them. The rest is pretty much standard. gdb/ChangeLog: * auto-load.h (debug_auto_load): Move here. (auto_load_debug_printf): New. * auto-load.c: Use auto_load_debug_printf. (debug_auto_load): Move to header. * linux-thread-db.c (try_thread_db_load): Use auto_load_debug_printf. * main.c (captured_main_1): Likewise.
