From 0decf84217f1ef8af132948a0661559a96961495 Mon Sep 17 00:00:00 2001 From: Harry van Haaren Date: Tue, 5 Sep 2017 14:27:58 +0100 Subject: [PATCH] buildtools: zero elf info variable in pmdinfogen This commit zeros out the elf_info struct at startup of the pmdinfogen code. If it is not zeroed, later in the code gcc produces "may be unused" prints. Clang does not report any issue. This issue is only observed when compiling pmdinfogen as an optimized build, hence this warning is not disabled in the existing Makefile. This commit enables a simplification in the meson build system, removing the requirement for "-Wno-maybe-uninitialized".
