| | | | | | | | | | | | | | | | | | | | | | matcher to state-machine(s) Summary: Replace the matcher if-statements for each rule with a state-machine. This significantly reduces compile time, memory allocations, and cumulative memory allocation when compiling AArch64InstructionSelector.cpp.o after r303259 is recommitted. The following patches will expand on this further to fully fix the regressions.

* [X86] Add comment string for broadcast loads from the constant pool.Craig Topper2017-07-041-37/+156
| | | | | | | | | | | | | | | | | Summary: When broadcasting from the constant pool its useful to print out the final vector similar to what we do for normal moves from the constant pool. I changed only a couple tests that were broadcast focused. One of them had been previously hand tweaked after running the script so that it could check the constant pool declaration. But I think this patch makes that unnecessary now since we can check the comment instead.

Small offsets (small enough to fit in a 16-bit signed immediate) can be used and are added to the symbol address after it is loaded from the GOT. Larger offsets are currently unsupported and result in an error from the assembler.
