761c8352f494 [svn r235] rough port of GDC's inline assembler code, unfinished ChristianK parents: diff changeset	138 1) Reference the label with a reachable goto statement
761c8352f494 [svn r235] rough port of GDC's inline assembler code, unfinished ChristianK parents: diff changeset	139 2) Have reachable computed goto in the function

761c8352f494 [svn r235] rough port of GDC's inline assembler code, unfinished ChristianK parents: diff changeset	145 The current solution is output our own private labels (as asm
