[PATCH 28/30] gcc-plugins: allow to enable GCC_PLUGINS for COMPILE_TEST

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 said 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.
