           Summary: GDC fraudulently defines D_InlineAsmX86
           Product: DGCC aka GDC
           Version: 0.23
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: wrong-code
          Severity: blocker
          Priority: P1
         Component: glue layer

Because GDC does not implement the D calling convention (issue 1805), inline
asm generally doesn't work for GDC. Valid D code results in bad code generation
and segfaults.
The workarounds for this are truly horrible.
Fortunately, the fix for this problem is simple: stop defining D_InlineAsmX86
until the D calling convention is supported. This should only require changes
to one line of code.
Optionally it could be changed to Gnu_InlineAsmX86.

I've ranked this as blocker, because I do not think that any library should
support GDC while this problem exists.

It would even be worth re-releasing the current version of GDC with no other
changes other than fixing this problem. It is the root cause of bugs such as
#1230, and many workarounds in Tango.
