[mips][mips16] MIPS16 is not a CPU/Architecture but is an ASE. Summary: The -mcpu=mips16 option caused the Integrated Assembler to crash because it couldn't figure out the architecture revision number to write to the .MIPS.abiflags section. This CPU definition has been removed because, like microMIPS, MIPS16 is an ASE to a base architecture.

Part 1 of 3 patches that completes very long conditional branches in constant islands for Mips16. We introdcuce JalB16 as a synomnym for Jal16. It makes it easier to read and is also necessary because Jal16 is a call instruction but JalB16 is being used as a branch. Various parts of LLVM will not work properly even in this late stage of the backend if we use what was declared as a call instruction to function as a branch. For one, basic block labels may not get emitted in some situations. llvm-svn: 195968

IR: Make metadata typeless in assembly Now that `Metadata` is typeless, reflect that in the assembly. These are the matching assembly changes for the metadata/value split in r223802. - Only use the `metadata` type when referencing metadata from a call intrinsic -- i.e., only when it's used as a `Value`. - Stop pretending that `ValueAsMetadata` is wrapped in an `MDNode` when referencing it from call intrinsics. So, assembly like this: define @foo(i32 %v) { call void @llvm.foo(metadata !{i32 %v}, metadata !0) call void @llvm.foo(metadata !{i32 7}, metadata !0) call void @llvm.foo(metadata !1, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{metadata !3}, metadata !0) ret void, !bar !2 } !0 = metadata !{metadata !2} !1 = metadata !{i32* @global} !2 = metadata !{metadata !3} !3 = metadata !{} turns into this: define @foo(i32 %v) { call void @llvm.foo(metadata i32 %v, metadata !0) call void @llvm.foo(metadata i32 7, metadata !0) call void @llvm.foo(metadata i32* @global, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{!3}, metadata !0) ret void, !bar !2 } !0 = !{!2} !1 = !{i32* @global} !2 = !{!3} !3 = !{} I wrote an upgrade script that handled almost all of the tests in llvm and many of the tests in cfe (even handling many `CHECK` lines). I've attached it (or will attach it in a moment if you're speedy) to PR21532 to help everyone update their out-of-tree testcases. This is part of PR21532. llvm-svn: 224257
