Jean Perier	8dea00f4e7	[flang] Add hlfir.concat operation definition ... This operation represents scalar character concatenation. This is added as part of flang lowering update described in https://github.com/llvm/llvm-project/blob/main/flang/docs/HighLevelFIR.md A notable difference with Fortran concatenation is that hlfir.concat can take two or more operands. This will be used to optimize concatenation chains. Differential Revision: https://reviews.llvm.org/D138650	2022-11-25 09:34:15 +01:00
Jean Perier	32e7e17d86	[flang] Add hlfir.declare operation ... This operation will be used to declare named variables in HLFIR. See the added description in HLFIROpBase.td for more info about it. The motivation behind this operation is described in https://reviews.llvm.org/D137634. The FortranVariableInterface verifier is changed a bit. It used to operate using the result type to verify the provided shape and length parameters. This is a bit incorrect because what matters to verify the information is the input address (This worked OK with fir.declare where the input memref type is the same as the output result). Also, not all operation defining variables will have an input memref with the same meaning (hlfir.designate and hlfir.associate for instance). Hence, this verifier is now optional and must be provided a memref to operate. Differential Revision: https://reviews.llvm.org/D137781	2022-11-14 10:27:12 +01:00
Jean Perier	af8cec4c16	[flang][NFC] move HLFIR dialect definition in IR ... Transforms will need to be put in a different library to avoid circular dependencies with other parts of the compiler. So create an IR directory, this (flat include directory, IR and Transform directories in lib) matches how dialects like LLVM dialect are implemented.
