Hi, Chris > That is target independent code, so you should not put sparc specific changes there.  It sounds like one of the sparc-specific target hooks is wrong. Since sparc does not provide any hooks for operation of branches (e.g. AnalyzeBranch and friends) it might be possible that generic codegen code is broken in absence of these hooks. -- With best regards, Anton Korobeynikov Faculty

...type inference errors when multiple types are added to a register class. In the output pattern, it is no longer necessary to duplicate the register classes or types of register operands. For immediate operands, the 'imm' tag is still required: def : Pat<(subc i32:$b, simm13:$val), (SUBCCri $b, imm:$val)>; I would like for the old register class notation to go away eventually. /jakob
