From 223bf296b23e7c610225b0798f68d67c6ae0f050 Mon Sep 17 00:00:00 2001 From: Thomas Schwinge Date: Mon, 11 Nov 2019 09:05:27 +0100 Subject: [PATCH] [build] Properly track GCC language configure fragments The 'gcc/configure' script sources all 'gcc/*/config-lang.in' files, but fails to emit such dependency information into the build machinery. That means, currently, when something gets changed in a 'gcc/*/config-lang.in' file, this is not noticed, and doesn't propagate through the build machinery. Handling of configure fragments is modelled in the same way as it already exists for Makefile fragments. gcc/ * Makefile.in (LANG_CONFIGUREFRAGS): Define. (config.status): Use/depend on it. * configure.ac (all_lang_configurefrags): Track, 'AC_SUBST'. * configure: Regenerate.
