fanquake 31c9987976 Merge #20447: depends: Patch qt_intersect_spans to avoid non-deterministic behavior in LLVM 8 ... 8f7d1b39ef Fix QPainter non-determinism on macOS (Andrew Chow) Pull request description: Aplies a patch to Qt that fixes the non-determinism by modifying Qt. The source of the non-determinism is how LLVM 8 optimizes qt_intersect_spans when compiling. The particular optimization that seems to be causing the problems is that a temp variable is being added for spans->y. For some reason, when it does this, it chooses different instructions to use when making that variable. We bypass this problem by patching qt_intersect_spans to always make and use this local variable. Potential alternative to #20436 and #20440 ACKs for top commit: hebasto: re-ACK 8f7d1b39ef ~for merging into the 0.21 branch, but [not into the master](https://github.com/bitcoin/bitcoin/pull/20454) branch.~ fanquake: ACK 8f7d1b39ef Tree-SHA512: b0d00a77643554021736524fb64611462ef2ec849a220543c12d99edb0f52f2e8128d2cc61fa82176b7e13b294574774a92d6b649badf8b7630c6d6a7e70ce10		4 years ago
