Subject: sanitizer_allocator_test: guard SpecialSizeClassMap test with !ALLOCATOR64_SMALL_SIZE
X-Git-Tag: upstream/17.0.6~3614
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dcef530878e870cd72479e7ecda6b059ebe00175;p=platform%2Fupstream%2Fllvm.git

sanitizer_allocator_test: guard SpecialSizeClassMap test with !ALLOCATOR64_SMALL_SIZE

This artificial size class map uses a very large kMaxSize (1<<34) which is not
suitable for small kAddressSpaceSize systems (aarch64-*-linux-android, riscv64).
Exposed by D153664.
