Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.
Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)
Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out
the CPUs the AArch64 emulator can emulate):
qemu-system-aarch64 -M virt -cpu help
| void Bag::reindexChunk(uint64_t chunk_pos) { | |
| map<uint32_t, multiset<IndexEntry> >::iterator cit; | |
| std::map<uint32_t, uint32_t>::iterator it; | |
| ChunkHeader chunk_header; | |
| ChunkInfo chunk_info; | |
| bool chunk_ok = false; | |
| uint32_t data_size = 0; | |
| uint8_t op = 0xff; | |
| readChunkHeader(chunk_header); | |
| if (chunk_header.compressed_size == 0) { |

PRs are a great way of sharing information, and can help us be aware of the changes that are occuring in our codebase. They are also an excellent way of getting peer review on the work that we do, without the cost of working in direct pairs.
Ultimately though, the primary reason we use PRs is to encourage quality in the commits that are made to our code repositories
Done well, the commits (and their attached messages) contained within tell a story to people examining the code at a later date. If we are not careful to ensure the quality of these commits, we silently lose this ability.
