Initially, ld->mv instructions were used for scalar_to_vector (load X), so this patch allows scalar_to_vector (load X) to utilize: LXSD and LXSDX for i64 and f64 LXSIWAX for i32 (sign extension to i64) LXSIWZX for i32 and f64 Committing on behalf of Amy Kwan.

Directly applying updates is usually slower than recalculating the whole domtree in this case. This patch fixes an issue which causes JT running slowly on some inputs. In bug 37929, the dominator tree is trying to apply 19,000+ updates several times, which takes several minutes.

------------------------------------------------------------------------ r341919 | atanasyan | 2018-09-11 02:57:25 -0700 (Tue, 11 Sep 2018) | 18 lines [mips] Add a pattern for 64-bit GPR variant of the `rdhwr` instruction MIPS ISAs start to support third operand for the `rdhwr` instruction starting from Revision 6. But LLVM generates assembler code with three-operands version of this instruction on any MIPS64 ISA. The third operand is always zero, so in case of direct code generation we get correct code. This patch fixes the bug by adding an instruction alias. The same alias already exists for 32-bit ISA. Ideally, we also need to reject three-operands version of the `rdhwr` instruction in an assembler code if ISA revision is less than 6. That is a task for a separate patch.

When these instructions are emitted for microMIPS R6 targets, `Mips::MipsR62MicroMipsR6` nor `Mips::Std2MicroMipsR6` cannot find correct op-codes and as a result the backend uses mips32 variant of the instructions encoding.

This may not be true, esp. for optimiation level 0. For example, in the above bug, for the following two static variables: @bpf_map_lookup_elem = internal global i8* (i8*, i8*)* inttoptr (i64 1 to i8* (i8*, i8*)*), align 8 @bpf_map_update_elem = internal global i32 (i8*, i8*, i8*, i64)* inttoptr (i64 2 to i32 (i8*, i8*, i8*, i64)*), align 8 The static variable @bpf_map_update_elem will have a symbol offset of 8 and a FK_SecRel_8 with FixupValue 8 will cause the assertion if llvm is built with -DLLVM_ENABLE_ASSERTIONS=ON. The above relocations will not exist if the program is compiled with optimization level -O1 and above as the compiler optimizes those static variables away. In the below error message, -O2 is suggested as this is the common practice. Note that FixedValue = 0 in applyFixup() does exist and is valid, e.g., for the global variable my_map in the above bug. The bpf loader will process them properly for map_id's before loading the program into the kernel. The static variables, which are not optimized away by compiler, may have FK_SecRel_8 relocation with non-zero FixedValue. The patch removed the offending assertion and will issue a hard error as below if the FixedValue in applyFixup() is not 0. $ llc -march=bpf -filetype=obj fixup.ll LLVM ERROR: Unsupported relocation: try to compile with -O2 or above, or check your static variable usage Signed-off-by: Yonghong Song <yhs@fb.com> ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_70@341038 91177308-0d34-0410-b5e6-96231b3b80d8

There is code trying to delete dead code that does so by e.g. checking if the single predecessor of a block is the block itself. That check fails on a block like this bb: br i1 undef, label %bb, label %bb since that has two (identical) predecessors. However, after the check for dead blocks there is a call to ConstantFoldTerminator on the basic block, and that call simplifies the block to bb: br label %bb Therefore we now do the call to ConstantFoldTerminator before the check if the block is dead, so it can realize that it really is. The original behavior lead to the block not being removed, but it was simplified as above, and then we did a call to Dest->replaceAllUsesWith(&*I); with old and new being equal, and an assertion triggered.
