File 0001-gdb-Add-aliases-for-read_core_file_mappings-callback.patch of Package gdb
From aa95b2d43883666937d31335d0178d2218d9c9aa Mon Sep 17 00:00:00 2001 From: Aaron Merey <amerey@redhat.com> Date: Tue, 9 Nov 2021 16:47:36 -0500 Subject: [PATCH] gdb: Add aliases for read_core_file_mappings callbacks Add aliases read_core_file_mappings_loop_ftype and read_core_file_mappings_pre_loop_ftype. Intended for use with read_core_file_mappings. Also add build_id parameter to read_core_file_mappings_loop_ftype. --- gdb/arch-utils.c | 15 +++++---------- gdb/arch-utils.h | 15 +++++---------- gdb/corelow.c | 2 +- gdb/gdbarch.c | 2 +- gdb/gdbarch.h | 16 ++++++++++++++-- gdb/gdbarch.sh | 14 +++++++++++++- gdb/linux-tdep.c | 19 +++++++------------ 7 files changed, 46 insertions(+), 37 deletions(-) Index: gdb-11.1/gdb/arch-utils.c =================================================================== --- gdb-11.1.orig/gdb/arch-utils.c +++ gdb-11.1/gdb/arch-utils.c @@ -1072,16 +1072,11 @@ default_get_pc_address_flags (frame_info /* See arch-utils.h. */ void -default_read_core_file_mappings (struct gdbarch *gdbarch, - struct bfd *cbfd, - gdb::function_view<void (ULONGEST count)> - pre_loop_cb, - gdb::function_view<void (int num, - ULONGEST start, - ULONGEST end, - ULONGEST file_ofs, - const char *filename)> - loop_cb) +default_read_core_file_mappings + (struct gdbarch *gdbarch, + struct bfd *cbfd, + read_core_file_mappings_pre_loop_ftype pre_loop_cb, + read_core_file_mappings_loop_ftype loop_cb) { } Index: gdb-11.1/gdb/arch-utils.h =================================================================== --- gdb-11.1.orig/gdb/arch-utils.h +++ gdb-11.1/gdb/arch-utils.h @@ -295,14 +295,9 @@ extern std::string default_get_pc_addres CORE_ADDR pc);
