...rrayidx, align 1 ret void } declare signext i8 @cnv(i8*) Now originally (at the time I hadn't added 8/16 bit register support) I had made the calling convention return values promote i8 & i16 to i32 : def RetCC_test : CallingConv<[ // Promote i8 returns to i32.

Dear there, I have a target which is supporting the 32 bit operations natively. Right now,I want to make it support the 16 bits operations as well. My initial thought is: (1) I can adding something like “ CCIfType< [i16], CCPromoteToType<i32>>”, to the CallingConv.td, then “all” the 16 bits operands will be automatically promoted to 32 bits, it will be all set. but looks it is not the case. (2) Then I tried adding something like “ setOperationAction(ISD::ADD, MVT::i16, Promote)” to the IselLowering, it still failed to...

Although it's not generally needed for ARM's use of CCCustom, I return two bools to handle the four possible outcomes to keep the mechanism flexible: * if CCCustomFn handled the arg or not * if CCCustomFn wants to end processing of the arg or not I placed the "unsigned i" outside those loops because i is used after the loop. If there's a better index search pattern, I'd

Hello. My target architecture supports natively 16 bit integers (i16). Whenever I write in C programs using only short types, clang compiles the program to LLVM and converts the i16 data to i32 to perform arithmetic operations and then truncates the results to i16. Then, the InstructionCombining (INSTCOMBINE or IC) pass removes these conversions back and forth from i16, except for
