Technical tradeoffs
- • Adds complexity to the relaxation pass to handle TLSDESC, potentially increasing compile/link times slightly.
- • The in-place rewrite for non-relaxed sequences might introduce slightly larger code sizes than a fully relaxed sequence.

[PATCH v5 4/4] RISC-V: Introduce TLSDESC relaxation.
This patch introduces TLSDESC relaxation for RISC-V executables, allowing Thread-Local Storage (TLS) descriptors to function in static environments. It modifies the relax pass to either delete instructions in relaxed sequences or rewrite them in place for non-relaxed cases, ensuring TLSDESC works correctly in static executables where runtime resolution is not possible. This fixes a limitation in how TLSDESC was handled previously.
