Cctools 6.5 Review

: Let's say there's a tool for compiling code. You might use it like this:

While modern LLVM natively understands how to output Mach-O files without needing a separate assembler step, Cctools 6.5 remains irreplaceable for projects that depend on strict GCC 4.x compatibility or require authentic bug-for-bug reproduction of legacy compiled binaries.

Cctools 6.5 marks a shift from feature-additive releases to a stability-and-performance release. Over the last quarter, telemetry showed that 60% of build failures were related to out-of-order execution in the legacy pipeline. We fixed the root cause.
