Subject: 	* solist.h (master_so_list): New function.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f8766ec10093029c944914de6c048d015e8dd5db;p=binutils-gdb.git

	* solist.h (master_so_list): New function.
	* solib.c (master_so_list): Likewise.
	* solib-svr4.c (enable_break): Iterate over so_list entries
	obtained from master list instead of entries obtained directly
	via svr4_current_sos().
