From: Tom Tromey Date: Sun, 21 Apr 2019 15:34:16 +0000 (-0600) Subject: Convert auto-load.c to type-safe registry API X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e85e19b4d7d9b3b322f27684f8c0a3a9ac0e57ab;p=binutils-gdb.git Convert auto-load.c to type-safe registry API This changes auto-load.c to use the type-safe registry API. It also changes a couple of types to "bool", removing uses of "FALSE". gdb/ChangeLog 2019-05-08 Tom Tromey * auto-load.c (struct auto_load_pspace_info): Add destructor and initializers. : Now bool.
