Ben Wiederhake	292871c4bc	UserspaceEmulator: Handle MAP_FIXED with invalid addresses better ... Old behavior: Crash due to VERIFY, unless we're completely and entirely out of memory (m_available_ranges being empty), in which case it would return -ENOMEM. New behavior: Return ENOMEM (and don't crash). In the case of nullptr, also emit a helpful diagnostic. Note that MAP_FIXED with nullptr is technically okay, but tends to be a sign that something went wrong. Also, this should improve mmap performance marginally, as it pulls the check out of a loop that does not modify any parts of the check. UE is now self-hosting! Fixes #5709. However, this still needs some love: "ue UserspaceEmulator true" spits out tons of error messages, probably false-positives, and takes about 229 seconds to run. Then again, true-in-ue-in-ue-in-Qemu is three levels of emulation, so no wonder it takes a long time! :D	2021-03-11 08:54:54 +01:00
