Why isn't other punctuation allowed? It would be very useful to be able to print strings without the trailing newline.

Strings don't have a trailing newline.

The lowering for them in LLVM::createPrintStrCall adds one unconditionally.

I'll post a complete patch for this in a bit, but I was thinking something along the lines of:

hm that's odd, I verified no newline is printed for strings yesterday and that seems to be the case, are we seeing different behaviour? The createPrintStrCall for vector.print <str> already has addNewLine=false

llvm-project/mlir/lib/Conversion/VectorToLLVM/ConvertVectorToLLVM.cpp

Lines 1520 to 1523 in 4014e2e

if (auto stringLiteral = printOp.getStringLiteral()) {
LLVM::createPrintStrCall(rewriter, loc, parent, "vector_print_str",
*stringLiteral, *getTypeConverter(),
/*addNewline=*/false);

although for empty string it will print newline as that wont be entered.

It follows on for #68973 (which removes all uses of printCString()), so I'll follow this up after that.
