-/* GCC does not support jumps from asm statements.  When optimization
-   is turned on, labels referenced only from asm statements will not
-   be output at the correct location.  There are ways around this:
-
-   1) Reference the label with a reachable goto statement
-   2) Have reachable computed goto in the function
-   3) Hack cfgbuild.c to act as though there is a computed goto.
-
-   These are all pretty bad, but if would be nice to be able to tell
-   GCC not to optimize in this case (even on per label/block basis).
-
-   The current solution is output our own private labels (as asm
-   statements) along with the "real" label.  If the label happens to
-   be referred to by a goto statement, the "real" label will also be
-   output in the correct location.
-
-   Also had to add 'asmLabelNum' to LabelDsymbol to indicate it needs
-   special processing.
-
-   (junk) d-lang.cc:916:case LABEL_DECL: // C doesn't do this.  D needs this for referencing labels in inline assembler since there may be not goto referencing it.
