@seven-mile thanks a bunch for working on this, I filled #1029 with more details on what was the plan here.
Which one do you think help us get to #1029 faster? |
…1096) 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: With `constBuilderCall` specified, we can apply `DefaultValuedAttr` 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 attribute `cir::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.
