...9;d like to start with is support for aligned instruction bundles in MC (assembler) level. This support exists in gas since binutils version 2.23 (http://sourceware.org/binutils/docs/as/Bundle-directives.html#Bundle-directives). Succinctly, the initial proposal is to add the following directives: .bundle_align_mode <num> .bundle_lock .bundle_unlock With the following semantics: When aligned instruction bundle mode ("bundling" in short) is enabled (.bundle_align_mode was encountered with an argument > 0, which is the power of 2 to which the bundle size is equal), single instructions and g...

Maybe I'm jumping the gun, but some initial thoughts after browsing the MC layer changes: * .bundle_align_start -> .bundle_align_mode N ? * .bundle_align_end -> .bundle_align_mode 0 ? * Add unit test showing .bundle_lock/unlock can be nested. I like the way you modified the existing ARM tests to show how the existing instructions are predicated. Overall, I think the concept of Native Client is well-documented and easy to...

The initial proposal does not cover .bundle_align{start|end} on purpose, to keep things simple. We do plan to add them, eventually, probably as attributes on .bundle_lock. > * Add unit test showing .bundle_lock/unlock can be nested....
