--- Comment #26 from Jesper Schmitz Mouridsen <j...@freebsd.org> --- (In reply to Jesper Schmitz Mouridsen from comment #25) Ok the difference in my understanding between arm64 and arm64/aarch64 on AMD64 the address pointer is always a valid firefoz jit region i.e 47th bit and above are never set. This is not true for arm64 so MapAlignedPagesRandom returns null when the last attempts are not in a validRange. Furthermore I cannot confirm that linuxes randomizes mmap'ed virtual addresses, so TryToAlignChunk works better there. -- You are receiving this mail because: You are on the CC list for the bug.
