Hello everyone, I would like to ask a question about the address calculation in TableGen. I replace a definition in MipsInstrInfo.td: def : Pat<(i32 (extloadi16_a addr:$src)), (LHu addr:$src)>; to: def : Pat<(i32 (extloadi16_a addr:$src)), (OR (LBu addr:$src), (SLL (LBu addr:($src+1)), 8))>; However, it failed to compiled. It seems that ($src+1) is a wrong representation in TableGen. I find the definition of adds: def addr : ComplexPattern<iPTR, 2, "SelectAddr", [frameindex], [SDNPWantParent]>; How to calculate a new address in TableGen?...

Hi, it seems that ipconfig has a problem if multiple devices are up and connected to the same network. It seems that it uses the wrong socket/device index to compare it to incoming packet. To be more precise, the packet gets discarded in do_pkt_recv as the ifindex from state differs always from the incoming packet To reproduce create two tap devices: $ sudo tunctl -u uli -t tap0

..., so simply partitioning the immediate into four 16-bit parts will not work. Here are some examples: 1. Imm = 0x000000007fff0000 LUi $dst, 7ffff // load immediate to upper 16-bit 2. Imm = 0x000000007fffffff LUi $r0, 7ffff ORi $dst, $r0, fffff 3. Imm = 0x00000fffffffffff ADDiu $r0, $zero, 1 SLL $r1, $r0, 44 // 44-bit shift left logical ADDiu $dst, $r1, fffff // add -1. the imm operand 0xffff is sign-extended to 64-bit when added. Currently, I have the following patterns (the last instruction of the sequence, or the root of the DAG, can be ADDiu, ORi, SLL or LUi): def : Pat<(isImmADD...

...win be installed. But if MinGW or Cygwin is installed, then I have no need for LLVM !! So the point is, Windoze developers will tend to reject LLVM while it requires that MinGW or Cygwin be installed, because MinGW/Cygwin eliminate the need for LLVM. The Solution: Make LLVM usable as a DLL or SLL in Windoze, capable of generating a finished ready-to-execute .EXE or .DLL file, without requiring that MinGW or Cygwin be installed first.
