But there is no requirement of any specific means or syntax.=20 we have been calling content addressable variables "sarts". So the first thing we must do is take almost any existing variable and identify it as a sart - that would be an attibute.=20 But it must also belong to a specific group/block/.... Name spaces could deal with this, but depending on the problem there could be one namespace for all CA variables or many different namespaces.=C2=A0 Basically the variable must be identified as content addressable, and it must be tagged as utilizing a specific address translation mechanism.=20 The next issue is that when the variable is used any type of bounds checking must be disabled because the "bounds" of a sart or content addressible variable are not easily known by the compiler.=20 Next the code generated for get/put will be different.=20 On Mon, 2023-12-18 at 08:59 +0100, Richard Biener via Gcc wrote: > On Sat, Dec 16, 2023 at 11:53=E2=80=AFPM Jonathan Wakely via Gcc > wrote: > >=20 > > On Sat, 16 Dec 2023 at 22:41, David H.
