Function rustc_codegen_ssa::base::wants_msvc_seh

pub fn wants_msvc_seh(sess: &Session) -> bool

Returns true if this session’s target will use SEH-based unwinding.

This is only true for MSVC targets, and even then the 64-bit MSVC target currently uses SEH-ish unwinding with DWARF info tables to the side (same as 64-bit MinGW) instead of “full SEH”.
