File pr31288-build-with-gcc14.patch of Package systemtap
From: Frank Ch. Eigler <fche@redhat.com> Date: Thu Jan 25 14:28:38 2024 -0500 Subject: PR31288: build with gcc14 Git-commit: 2604d135069f74cf5a223631cf92c9d0d818ef9c References: bsc#1221706 Signed-off-by: Tony Jones <tonyj@suse.de> X-Info: adjust patch, no 80642fc0d22abf9d5e19e705adfd7f12599ace7c PR31288: build with gcc14 GCC14 makes -Wmissing-prototypes defaultish on, which triggers on such gentle-spirited code as: void foo(void) { } when you should darn well know to have an exact duplicate declaration prototype first. Because of course. void foo(void); void foo(void) { } So anyway, with our fondness for -Werror, this broke the stap runtime autoconf* business, bits of the runtime, bits of the translator. Probably more stuff as yet unidentified. If your testsuite logs show: [...]: error: no previous prototype for ‘[...]’ [-Werror=missing-prototypes] this is probably to blame. Since this is coming to clang as well, we now get buildrun.cxx to force -Wmissing-prototypes on all the time, so as to try to notice occurrences of this problem earlier. diff --git a/buildrun.cxx b/buildrun.cxx index 76551415c..bb7bdcc9d 100644 --- a/buildrun.cxx +++ b/buildrun.cxx @@ -315,6 +315,7 @@ compile_pass (systemtap_session& s) o << "CHECK_BUILD := $(CC) -DMODULE $(NOSTDINC_FLAGS) $(KBUILD_CPPFLAGS) $(CPPFLAGS) " << "$(LINUXINCLUDE) $(_KBUILD_CFLAGS) $(CFLAGS_KERNEL) $(EXTRA_CFLAGS) " << "$(CFLAGS) -DKBUILD_BASENAME=\\\"" << s.module_name << "\\\" " + << "-Wmissing-prototypes " // GCC14 prep, PR31288 << WERROR << " -S -o /dev/null -xc " << endl; o << "stap_check_build = $(shell " << superverbose << " if $(CHECK_BUILD) $(1) " << redirecterrors << " ; then echo \"$(2)\"; else echo \"$(3)\"; fi)" << endl; @@ -345,6 +346,8 @@ compile_pass (systemtap_session& s) // o << module_cflags << " += -Iusr/include" << endl; // since such headers are cleansed of _KERNEL_ pieces that we need + o << module_cflags << " += -Wmissing-prototypes" << endl; // GCC14 prep, PR31288 + o << "STAPCONF_HEADER := " << s.tmpdir << "/" << s.stapconf_name << endl; o << ".DELETE_ON_ERROR: $(STAPCONF_HEADER)" << endl; o << "$(STAPCONF_HEADER):" << endl; diff --git a/runtime/linux/autoconf-access_ok_2args.c b/runtime/linux/autoconf-access_ok_2args.c index 2e5c79a65..3e6041dd2 100644 --- a/runtime/linux/autoconf-access_ok_2args.c +++ b/runtime/linux/autoconf-access_ok_2args.c @@ -1,5 +1,7 @@ #include <linux/uaccess.h> +int __something(void); + int __something(void) { return access_ok ((void*) 0, 4); diff --git a/runtime/linux/autoconf-alloc-percpu-align.c b/runtime/linux/autoconf-alloc-percpu-align.c index 158d579c0..912361269 100644 --- a/runtime/linux/autoconf-alloc-percpu-align.c +++ b/runtime/linux/autoconf-alloc-percpu-align.c @@ -1,6 +1,7 @@ #include <linux/percpu.h> /* kernel commit f2a8205c */ +void foo (void); void foo (void) { (void) __alloc_percpu(sizeof(int), 8); } diff --git a/runtime/linux/autoconf-asm-access-ok.c b/runtime/linux/autoconf-asm-access-ok.c index 1d0e61776..7a95758c2 100644 --- a/runtime/linux/autoconf-asm-access-ok.c +++ b/runtime/linux/autoconf-asm-access-ok.c @@ -1,5 +1,6 @@ #include <linux/uaccess.h> +bool foo(const void __user *ptr, size_t size); bool foo(const void __user *ptr, size_t size) { return __access_ok(ptr, size); diff --git a/runtime/linux/autoconf-atomic_fetch_add_unless.c b/runtime/linux/autoconf-atomic_fetch_add_unless.c index b765c39ef..b79c4742d 100644 --- a/runtime/linux/autoconf-atomic_fetch_add_unless.c +++ b/runtime/linux/autoconf-atomic_fetch_add_unless.c @@ -1,5 +1,7 @@ #include <linux/atomic.h> +int foo(atomic_t *v); + int foo(atomic_t *v) { return atomic_fetch_add_unless(v, 1, 0); diff --git a/runtime/linux/autoconf-bio-bi_opf.c b/runtime/linux/autoconf-bio-bi_opf.c index 20db781f3..047ccd68c 100644 --- a/runtime/linux/autoconf-bio-bi_opf.c +++ b/runtime/linux/autoconf-bio-bi_opf.c @@ -19,6 +19,8 @@ * No intended functional changes in this commit. */ +void bar (void); + void bar (void) { struct bio foo; diff --git a/runtime/linux/autoconf-cpu-clock.c b/runtime/linux/autoconf-cpu-clock.c index b501bcdf3..6c80afdad 100644 --- a/runtime/linux/autoconf-cpu-clock.c +++ b/runtime/linux/autoconf-cpu-clock.c @@ -29,7 +29,8 @@ // reference sched_clock_cpu().
