◆ convertInstructionImpl()
|
static |
Converts the LLVM instructions that have a generated MLIR builder.
Using a static implementation method called from the module import ensures the builders have to use the moduleImport argument and cannot directly call import methods. As a result, both the intrinsic and the instruction MLIR builders have to use the moduleImport argument and none of them has direct access to the private module import methods.

static |
Converts the sync scope identifier of inst to the string representation necessary to build an atomic LLVM dialect operation.

Upper bound on the characters a diagnostic renders for an LLVM entity.
One rendering is unbounded by nature: a GlobalVariable prints its entire initializer, and a node with long MDStrings or large inline constants prints them whole. On a merged library a single unbounded diagnostic reaches tens of megabytes, so every rendering path below truncates its output. Diagnostics only need to identify the entity; the full form is in the input being imported.
