[llvm-commits] Patch to generalize .weak_definition directive in MCAsmStreamer

[Dmitry N. Mikushin]

Dear all,

In NVPTX backend it is illegal to generate .weak_definition directive
in its default format. In order to let the target provide its own
implementation of this directive, MCAsmStreamer should emit
MAI.getWeakDefDirective() instead of hard-coded
"\t.weak_definition\t", in the same way as it is already done for
.globl/.global.

Please see the attached patch.

Thanks,
- D.
