Am I correct in assuming that DMD passes all the tests in the testsuite

Yes, as well as all druntime and phobos unittests (and regression 
testing of a few projects that people do of their own accord when a beta 
is announced).

but marking large parts of D code that way seems wrong...

I'm going to assume the vvvv() transformation is an
optimization. :)

I was after the vector support. But it's okay, I successfully managed to

Once I've refactored a few things, I will get onto this so that have
better control over what functions are forced to have a frame pointer
(ie: extern(D) with inline asm are the only ones really needed).

Since some time I try to somehow get a working 64-bit DLL compiled. With
gdc this works now apart from crashing in the TLS setup code, as soon as
the runtime is initialized (no TLS variables are used in the code).

Is TLS support and/or a workaround for those crashes something that's on
the radar?

issues have been fixed but I haven't uploaded a new binary.  The new 
compiler can pass most of the testsuite.  The current failures are not 
TLS related.

Since you're working with Dll's if you post a test case, I would be 
happy to test the compiler on it before uploading a new release.

TLS is a high priority for MinGW as it is required by D.

I just realized that the crash happens only when loading the DLL at runtime
using
LoadLibrary and that it is only partially a 32/64 bit problem (test2c crashes
for
64-bit but works for 32-bit).

The attached .zip contains a test script that runs a few different combinations.
The statically linked versions generally seem to work.

parent Daniel Green <venix1 gmail.com> writes:
All tests pass.  However, I see your problem.

In plaindll.d:

version(GNU){ // Workaround for linker error
	void* _tlsstart; // First symbol of the TLS section
	void* _tlsend;
	//int _tls_callbacks_a; // Workaround for GDC/MinGW linker error
}

_tlsstart is the first symbol of the TLS section. _tlsend is the last 
symbol of the TLS section.  Together they are used by D to identify the 
TLS memory region for a given thread.  If they do not come from TLS 
memory then things will not work right.

The MinGW runtime has equivalent symbols __tls_start and __tls_end. 
This is not something likely to change as it's a Windows convention. 
The version of MinGW/GDC you have should define _tlsstart and _tlsend 
symbols automatically if WinMain, DllMain or _Dmain functions exist in 
the current object file.

As of now MinGW/GDC uses alias __tls_start _tlsstart and alias __tls_end 
_tlsend to satisfy those requirements where necessary.

It's the same with _tls_callbacks_a.  Windows convention specifies __xl_a.

The currently posted MinGW64 binaries have an alignment issue with TLS 
memory in 64-bit mode.  It's a segfault that will manifest in the 
garbage collector.

I'll release updated binaries tonight.
