There was a problem hiding this comment.
I find this nomenclature confusing: the format of LSDA is not a part of the SEH spec, so both -gnu and -msvc are "full SEH". I think this should be called wants_msvc_lsda, or at least wants_msvc_seh.
This commit leverages the runtime support for DWARF exception info added in rust-lang#27210 to enable unwinding by default on 64-bit MSVC. This also additionally adds a few minor fixes here and there in the test harness and such to get `make check` entirely passing on 64-bit MSVC: * The invocation of `maketest.py` now works with spaces/quotes in CC * debuginfo tests are disabled on MSVC * A link error for librustc was hacked around (see rust-lang#27438)
