Commit 39bf4de89ff7 ("drm/i915: Add -Wall -Wextra to our build, set
warnings to full") enabled extra warnings for i915 to spot possible
bugs in new code, and then disabled a subset of these warnings to keep
the current code building without warnings (with gcc). Enabling the
extra warnings also enabled some additional clang-only warnings, as a
result building i915 with clang currently is extremely noisy. For now
also disable the clang warnings sign-compare, sometimes-uninitialized,
unneeded-internal-declaration and initializer-overrides. If desired
they can be re-enabled after the code has been fixed.Signed-off-by: Matthias Kaehlcke <m...@chromium.org> --- Changes in v3: - don't disable -Wunneeded-internal-declaration , the only occurrence can be fixed in the code - removed 'Fixes' tag, since backporting is not necessary drivers/gpu/drm/i915/Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/gpu/drm/i915/Makefile b/drivers/gpu/drm/i915/Makefile index 9bee52a949a9..dfe01452c8d1 100644 --- a/drivers/gpu/drm/i915/Makefile +++ b/drivers/gpu/drm/i915/Makefile @@ -18,6 +18,10 @@ subdir-ccflags-y += $(call cc-disable-warning, type-limits) subdir-ccflags-y += $(call cc-disable-warning, missing-field-initializers) subdir-ccflags-y += $(call cc-disable-warning, implicit-fallthrough) subdir-ccflags-y += $(call cc-disable-warning, unused-but-set-variable) +# clang warnings +subdir-ccflags-y += $(call cc-disable-warning, sign-compare) +subdir-ccflags-y += $(call cc-disable-warning, sometimes-uninitialized) +subdir-ccflags-y += $(call cc-disable-warning, initializer-overrides) subdir-ccflags-$(CONFIG_DRM_I915_WERROR) += -Werror # Fine grained warnings disable -- 2.17.0.441.gb46fe60e1d-goog _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
