LDC build issues for PowerPC and kfreebsd-{i386,amd64} on Debian

Mon Jul 14 10:23:04 PDT 2014

Hi all,

The ldc package on Debian has just reported 3 build failures:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754689
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754690

One is for PowerPC:

| (2101): Error: static assert  "Architecture not supported." make[3]:
| *** [runtime/src/core/thread.o] Error 1

And the other for kfreebsd-i386/kfreebsd-amd64:

I can work on the PowerPC one as I do have access to a Power7
Debian system -in fact I tried to fix the missing ExternStackShell
callee-save code (just tried saving GPR13-30 and GPR1) by adding some
inline asm, but the compiler failed to parse this file complaining that
I cannot use inline asm in PowerPC. Any ideas?

I guess the PowerPC port is easy to fix, and probably the kfreebsd-*
ports as well. In fact looking at past build history of the package, I
see that it was built on all architectures before ([1] no idea if it was
actually working on all of them, but it was built). If there is no
interest in fixing support for some ports, I can just remove them from
the architecture list and be done with it, but if there is a case that
ldc may be working again on them, then I'd be happy to give it a shot.
