bnjbvr closed issue #1885:

Feature

Support TLS data objects with COFF binaries.

Benefit

TLS data objects are already supported for ELF and Mach-O binaries.

Implementation

Add a new x86_coff_tls_get_addr instruction. See https://github.com/bjorn3/rustc_codegen_cranelift/issues/388#issuecomment-532930282 for what x86_64 instructions to lower the x86_coff_tls_get_addr instruction to. Then make changes to the object crate as necessary to generate TLS sections for COFF.

Alternatives

N/A
