Support for this rather fuzzy syntax is added by upstream commit: http://llvm.org/viewvc/llvm-project?view=revision&revision=229911 I will import this shortly, and it's also scheduled for the llvm/clang 3.6.1 release.

For compatiblity with GNU as. Binutils documents this as '.uleb128 expressions'. Subtle, isn't it?

If you want to close this out, I'm good.

I'm guessing that GAS understands the ARM assembly directive: .uleb128 94, 10 Clang --integrated-as does not: lj_vm_asm.s:2653:13: error: unexpected token in directive .uleb128 94, 10
