Hi All, I try to send a patch via thunderbird, I don't know if the process is correct. I tried from gmail but it was not good.
The patch is trivial and I use it to learn the patch submission process, along with the signed-off-by process Cheers, Phi
From 3ac65cf6eec36a9a22af378e89bc4d5b148d8713 Mon Sep 17 00:00:00 2001 From: Philippe Benard <phi.deb...@gmail.com> Date: Thu, 9 Jan 2025 14:59:00 +0100 Subject: [PATCH] libcpu: Remove false positive null ptr deref warning for GCC -O3 See bugzilla Bug#32527 * libcpu/Makefile.am i386_lex_CFLAGS += $(subst -O3,-Wno-null-dereference,$(findstring -O3,$(CFLAGS))) i386_lex_CFLAGS is a make variable to tweak the i386_lex.c.o specific compile flags. The are already some -W defined there, I'd like to add one to avoid seeing false warning during build with -O3 compile flag. GCC 14.2 (as well as 13.x) produce a false positive warning for the i386 lexer, a bug is filled already against GCC for that, CLANG is imune.
