| Test plain passthrough copying with llvm-objcopy, by checking that obj2yaml |
| produces identical output for both input and output object files/executables. |
| (Intentionally not comparing to the original input yaml, in case there are |
| superficial differences like line endings.) In order to have a check of the |
| whole file and not just individual fields with FileCheck, checking with |
| obj2yaml+cmp instead of llvm-readobj+cmp, as llvm-readobj also prints file |
| details that can differ between otherwise equal files (such as file offsets). |
| |
| Actual copied object files/executables can differ in, among others, the |
| following aspects: |
| - The padding of executable sections (lld uses 0xcc, which is int3 on x86) |
| - The actual layout of the string table (it can be filled linearly, |
| strings can be dedupliated, the table can be optimized by sharing tails |
| of longer strings; different parts in llvm do each of these three options) |
| - The size indication for an empty/missing string table can either be 4 |
| or left out altogether |
| - Alignment of section data |
| - Checksums |
