-Subject: [PATCH 3/7] gcc-plugins: drop support for GCC <= 4.7
-
-Nobody was opposed to raising minimum GCC version to 4.8 [1]
-So, we will drop GCC <= 4.7 support sooner or later.
-
-We always use C++ compiler for building plugins for GCC >= 4.8.
-
-This commit drops the plugin support for GCC <= 4.7 a bit earlier,
-which allows us to dump lots of code.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Remove "params.h" include, which has been dropped in GCC 10.
-
-Remove is_a_helper() macro, which is now defined in gimple.h, as seen
-when running './scripts/gcc-plugin.sh g++ g++ gcc':
-
-In file included from <stdin>:1:

- 1037 | is_a_helper <const ggoto *>::test (const gimple *gs)

-
-Add -Wno-format-diag to scripts/gcc-plugins/Makefile to avoid
-meaningless warnings from error() formats used by plugins:
-
-scripts/gcc-plugins/structleak_plugin.c: In function ‘int plugin_init(plugin_name_args*, plugin_gcc_version*)’:

-Subject: [PATCH 6/7] x86: Fix early boot crash on gcc-10, next try
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-... or the odyssey of trying to disable the stack protector for the
-function which generates the stack canary value.
-
-The whole story started with Sergei reporting a boot crash with a kernel
-built with gcc-10:
-
- Kernel panic — not syncing: stack-protector: Kernel stack is corrupted in: start_secondary
- CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.6.0-rc5—00235—gfffb08b37df9 #139
- Hardware name: Gigabyte Technology Co., Ltd. To be filled by O.E.M./H77M—D3H, BIOS F12 11/14/2013
- Call Trace:
- dump_stack
- panic
- ? start_secondary
- __stack_chk_fail
- start_secondary
- secondary_startup_64
- -—-[ end Kernel panic — not syncing: stack—protector: Kernel stack is corrupted in: start_secondary
-
-This happens because gcc-10 tail-call optimizes the last function call
-in start_secondary() - cpu_startup_entry() - and thus emits a stack
-canary check which fails because the canary value changes after the
-boot_init_stack_canary() call.
-
-To fix that, the initial attempt was to mark the one function which
-generates the stack canary with:
-
- __attribute__((optimize("-fno-stack-protector"))) ... start_secondary(void *unused)
-
-however, using the optimize attribute doesn't work cumulatively
-as the attribute does not add to but rather replaces previously
-supplied optimization options - roughly all -fxxx options.
-
-The key one among them being -fno-omit-frame-pointer and thus leading to
-not present frame pointer - frame pointer which the kernel needs.
-
-The next attempt to prevent compilers from tail-call optimizing
-the last function call cpu_startup_entry(), shy of carving out
-start_secondary() into a separate compilation unit and building it with
--fno-stack-protector, is this one.
-
-The current solution is short and sweet, and reportedly, is supported by
-both compilers so let's see how far we'll get this time.
