From 21ea5acdd1bcfe89984b16b5bac730050c5cf05e Mon Sep 17 00:00:00 2001 From: Sergio Durigan Junior Date: Tue, 25 Apr 2017 16:03:39 -0400 Subject: Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files) Due to my ongoing work to make it possible for gdbserver to start the inferior using the shell, I had to share the fork_inferior function under the "nat/" directory. In order to do that, I created a new file and put the function there; however, this meant that I now had to update some of the *.mh files (under "gdb/config") and add the new file as a dependency to be built natively. Bleh... After talking a bit to Pedro about this, the idea came up to write a new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would concentrate all of the native settings for each host/system. I decided to tackle this issue. The patch is simple. All of the previous Makefile variables that were being declared inside the *.mh files are now inside "gdb/Makefile.in", and "gdb/configure" is responsible for AC_SUBST'ing them. The definitions of these variables were put inside "gdb/configure.nat", so now they're shell variables. For excerpts of Makefile code, one must create a file under "gdb/config/${gdb_cpu_host}" and reference it on the "nat_extra_makefile_frag" variable. It should now be easier to update the native dependencies of hosts in this single file. This has been tested on x86_64 without regressions. gdb/ChangeLog: 2017-05-06 Sergio Durigan Junior * Makefile.in: Remove "@host_makefile_frag@".
