Synopsis: Request a "reachable" attribute for labels.
State-Changed-From-To: open->closed
State-Changed-By: geoffk
State-Changed-When: Thu Mar 27 00:53:28 2003
State-Changed-Why:
Changing flow of control in asm statements is not supported and does not work. The manual says:
jumps from one asm to another are not supported. The compiler's optimizers do not know about these jumps, and therefore they cannot take account of them when deciding how to optimize.
