...'s meaningless to discuss the semantics when important terms are undefined: * "stack map" (and the format of a stack map, and where it is emitted/how it can be accessed, etc.) * "shadow": while it's fairly clear roughly what is meant by this, this is Lang*Ref*, not "LangOverview" or "LangTour" It may be that the inherently experimental nature of these intrinsics do not lend itself to being documented adequately enough for inclusion in LangRef at this point, in which case I would suggest demoting this description to a new page for experimental intrinsics unt...

This is a proposal for adding Stackmaps and Patchpoints to LLVM. The first client of these features is the JavaScript compiler within the open source WebKit project. A Stackmap is a record of variable locations (registers and stack offsets) at a particular instruction address. A Patchpoint is an instruction address at which space is reserved for patching a new instruction sequence at runtime.

...th, at least, the description for x86 (and we can add descriptions for the other backends as they're validated). This looks like a very-useful piece of functionality. -Hal > * "shadow": while it's fairly clear roughly what is meant by this, > this is Lang*Ref*, not "LangOverview" or "LangTour" > > > It may be that the inherently experimental nature of these intrinsics > do not lend itself to being documented adequately enough for > inclusion in LangRef at this point, in which case I would suggest > demoting this description to a new page...

...e of functionality. I’m moving the intrinsic docs to a separate page, like exception intrinsics, and documenting the stack map format there. -Andy > > -Hal > >> * "shadow": while it's fairly clear roughly what is meant by this, >> this is Lang*Ref*, not "LangOverview" or "LangTour" >> >> >> It may be that the inherently experimental nature of these intrinsics >> do not lend itself to being documented adequately enough for >> inclusion in LangRef at this point, in which case I would suggest >> demoting this de...
