Following #1009 and #1028, this PR removes the double white spaces in the assembly format of
cir.global
op.It's basically some
mlir-tablegen
-builtin magic: WithconstBuilderCall
specified, we can applyDefaultValuedAttr
with any default value we can construct from constant values. Then we can easily omit the default in assembly. Hence, we don't need to compromise anything for the wrapper attributecir::VisibilityAttr
.Similarly to #1009, an empty literal
``
is used to omit the leading space emitted by inner attribute.The test case
visibility-attribute.c
is modified to save the intermediate CIR to disk and reflect the effects.Double whitespaces in other test files are removed.
