msan's app memory mappings for aarch64 are constrained by the MEM_TO_SHADOW constant to 64GB or less, and some app memory mappings (in kMemoryLayout) are even smaller in practice. This will lead to a crash with the error message "MemorySanitizer can not mmap the shadow memory" if the executable's memory mappings (e.g., libraries) extend beyond msan's app memory mappings. This patch makes the app/shadow/origin memory mappings considerably larger, along with corresponding changes to the MEM_TO_SHADOW and SHADOW_TO_ORIGIN constants. Note that this deprecates compatibility with 39- and 42-bit VMAs. Differential Revision: https://reviews.llvm.org/D137666 |
