[LLVMdev] non-x86 sanitizer buildbots: no rule to make target check-lsan etc.

[Jay Foad]

Hi,

Currently the first stage ("run sanitizer tests in gcc build") of the
sanitizer-ppc64-linux1 buildbot is only failing because of:

+ cd clang_build
+ make -j16 check-lsan
make: *** No rule to make target `check-lsan'.  Stop.
+ echo @@@STEP_FAILURE@@@
@@@STEP_FAILURE@@@
+ cd clang_build
+ make -j16 check-msan
make: *** No rule to make target `check-msan'.  Stop.
+ echo @@@STEP_FAILURE@@@
@@@STEP_FAILURE@@@
+ cd clang_build
+ make -j16 check-tsan
make: *** No rule to make target `check-tsan'.  Stop.
+ echo @@@STEP_FAILURE@@@
@@@STEP_FAILURE@@@
+ cd clang_build
+ make -j16 check-ubsan
make: *** No rule to make target `check-ubsan'.  Stop.
+ echo @@@STEP_WARNINGS@@@
@@@STEP_WARNINGS@@@
+ cd clang_build
+ make -j16 check-dfsan
make: *** No rule to make target `check-dfsan'.  Stop.
+ echo @@@STEP_WARNINGS@@@
@@@STEP_WARNINGS@@@

The problem is that the buildbot script
(zorg/buildbot/builders/sanitizers/buildbot_cmake.sh) explicitly lists
all the sanitizer check-* targets, but only some of them are supported
on non-x86 configurations. It seems silly for the buildbot script to
duplicate all the logic from compiler-rt's cmake/config-ix.cmake about
which sanitizers are supported on which targets.

Maybe compiler-rt could have a new check-all-compiler-rt target, which
runs the checks for all supported sanitizers? Is it possible to
implement this (it would be a lit target that subsumes a bunch of
other lit targets)?

Any other ideas?

Thanks,
Jay.
