From 8c4b5f3d987c80a1746e3f198bb060d7d7671945 Mon Sep 17 00:00:00 2001 From: Michael Weghorn Date: Mon, 25 May 2020 11:38:32 -0400 Subject: [PATCH] gdbsupport: Let construct_inferior_arguments take gdb::array_view param Adapt the construct_inferior_arguments function to take a gdb::array_view parameter instead of a char * array and an int indicating the length and adapt the only call site. This will allow calling it more simply in a follow-up patch introducing more uses of the function. gdbsupport/ChangeLog: * common-inferior.cc, common-inferior.h (construct_inferior_arguments): Adapt to take a gdb::array_view parameter. Adapt call site.
