784 regressions between DMD-0.158 and DMD-0.160 were found,
however all of them are inline assembler tests that previously
failed to compile and now fail to run if compiled with "-fPIC".

 784 regressions between DMD-0.158 and DMD-0.160 were found,
 however all of them are inline assembler tests that previously
 failed to compile and now fail to run if compiled with "-fPIC".

The tests rely on accessing static data from inline assembler. Accessing 
static data with -fPIC requires special code to be generated, but with 
inline assembler you have to add that code in manually. The compiler 
won't do it automatically - after all, inline assembler means you 
control the flame!

So I don't believe it's a compiler bug.

You can alter the inline assembler to pick the data off the stack 
instead of static data, then it should work.

I never checked how DMD stores constant data ... will take some time to fix.
How about defining version=D_PIC if compiling with -fPIC, just like D_Coverage?

Should was the right word ^_^

Thomas -

Are all of the active DStress bugs included in bugzilla yet?
If not, is there any easy way to tell which are missing?

You work on DStress is much appreciated, it really makes D feel like a 
solid product.

No.

 If not, is there any easy way to tell which are missing?

1) Find all test cases with unexpected results.

2) Ignore all asm_* test for now.

3) Ensure that the test case isn't buggy.

4) Ignore all test that contain the string "puremagic.com/bugzilla".

5) Ignore all test cases whose names could be found in the bugzilla.

6) After preparing snacks and drinks: File the bug in bugzilla and
include links to the original bug report as well as to the test case(s).
