Revert "[ms-cxxabi] Add a new calling convention that swaps 'this' and 'sret'"

This reverts commit r200561.

This calling convention was an attempt to match the MSVC C++ ABI for
methods that return structures by value.  This solution didn't scale,
because it would have required splitting every CC available on Windows

that (r208458), revert this hack.

10 years agoAllow sret on the second parameter as well as the first
Reid Kleckner [Fri, 9 May 2014 22:32:13 +0000 (22:32 +0000)]
Allow sret on the second parameter as well as the first

MSVC always places the implicit sret parameter after the implicit this
parameter of instance methods.  We used to handle this for
x86_thiscallcc by allocating the sret parameter on the stack and leaving
the this pointer in ecx, but that doesn't handle alternative calling
conventions like cdecl, stdcall, fastcall, or the win64 convention.

Instead, change the verifier to allow sret on the second parameter.

This also requires changing the Mips and X86 backends to return the
argument with the sret parameter, instead of assuming that the sret
parameter comes first.

The Sparc backend also returns sret parameters in a register, but I
wasn't able to update it to handle secondary sret parameters.  It
currently calls report_fatal_error if you feed it an sret in the second
parameter.
