Awesome presentation.

The most instructive so far.
Details of Internal representation of GCC - I never even heard of names like GIMPLE or GENERIC. Very useful and informative stuff even for use outside of D related tasks.

Thanks Iain! :)

Errata:  David Nadlinger - the way it determines whether or not to emulate TLS is at the configure stage, where it tests if the assembler has support for it.  If no, then TLS is emulated.  So the correct answer would be:  It's not something handled by the compiler, if the runtime support TLS, that is good, but we also require support in the assembler also.  If support is there then it should be plain sailing. I don't follow development of the GNU toolchain for Windows, but so far as I know it isn't... yet.

We (LDC) use the GNU as on MinGW as well, as the LLVM integrated assembler doesn't support emitting the Dwarf EH tables into COFF files yet. So, you should be good to go in theory, although the target config handling code you mentioned might also need some adaption – I haven't really looked at that part of GCC at all yet.

You do need a fairly recent, maybe even unreleased version of binutils for SECREL32 relocations to work though, same for my fixes in the mingw64-w32 runtime,

Wonderful talk, Iain. :-)

One question about the copyright assignment issue.  How does this operate in practice?  Is it going to be that the D frontend will simply go forward as copyright (c) FSF (which isn't a problem DMD-wise as their assignment agreement immediately licenses the code back under completely unrestricted terms), or will it operate on a per-release basis (where basically every time a new D frontend release is pushed to GCC, the copyright is also transferred)?

Walter will know the answer to this one, as well as what clauses come under the assignment.
