(bug): Non-determinate assembly generation #19

Closed arkamnite closed 1 year ago

arkamnite commented 1 year ago

Non-determinate assembly generation

Occasionally, depending on how many times you run the build tools, the assembly produced will change and contain out instructions. Additionally, consequent re-runs will cause a segmentation fault. Building does not work using clang.

[x] Work out what the out instruction is.
[x] Establish how to cause the issue.
[x] Isolate breaking changes and solve them incrementally.

Problem has been solved with proper implementation of prologue and epilogue insertion.
