The team I am working with is using asm statements containing label definitions as a way of instrumentation so that when an application is loaded into their debug and test framework, the labels will cause breakpoints to be set at strategic points where they can query the state of the processor that the application is running on. ~ Todd From: Eli Friedman [mailto:efriedma at quicinc.com] Sent:

...his tactic has been tried before, I'm pretty sure. It's an attempt to do simple instrumentation without having to hack the compiler itself (you do some manual coding or preprocessing, and poof you get useful info in your object file). But our compiler is too clever. Some sort of "No Touchee!" constraint would help this use-case a lot. --paulr From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of Snider, Todd via llvm-dev Sent: Tuesday, February 12, 2019 3:06 PM To: Eli Friedman; llvm-dev at lists.llvm.org Subject: Re: [llvm-dev] [RFC] Potential extension to asm...
