Subject: [PATCH v5 30/31] gcc-plugins: allow to enable GCC_PLUGINS for COMPILE_TEST
Date: Mon, 28 May 2018 18:22:07 +0900	[thread overview]
Message-ID: <1527499328-13213-31-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1527499328-13213-1-git-send-email-yamada.masahiro@socionext.com>

Now that the compiler's plugin support is checked in Kconfig,
all{yes,mod}config will not be bothered.

Remove 'depends on !COMPILE_TEST' for GCC_PLUGINS.

'depends on !COMPILE_TEST' for the following three are still kept:
  GCC_PLUGIN_CYC_COMPLEXITY
  GCC_PLUGIN_STRUCTLEAK_VERBOSE
  GCC_PLUGIN_RANDSTRUCT_PERFORMANCE

Kees suggested to do so because the first two are too noisy, and the
last one would reduce the compile test coverage.  I commented the
reasons in arch/Kconfig.
