From: Tankut Baris Aktemur Date: Fri, 29 Nov 2019 11:17:36 +0000 (+0100) Subject: gdb: improve debug output of function overload resolution X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a992a3b010983dc370c462dc467893724afbbde9;p=binutils-gdb.git gdb: improve debug output of function overload resolution Function overload resolution prints debug output if turned on via the 'set debug overload' command. The output includes the badness vector (BV). For each function, this vector contains a badness value of the length of parameters as its first element. So, BV[0] does not correspond to a parameter. The badness values of parameters start with BV[1]. A badness value is a pair; it contains a rank and a subrank. Printing both fields provides useful information. Improve printing the badness vector along these lines. gdb/ChangeLog: 2019-11-29 Tankut Baris Aktemur * valops.c (find_oload_champ): Improve debug output.
