Hi all, I'm trying to simulate an extended x86 architecture on gem5 with several new instructions. My hardware setup is done and now I'd like llvm to accept the existence of the new instruction passed in inline assembly and output the correct opcode and registers. I chose the two-byte opcode 0x0F 0x7A and I would like the instruction to have the same operands and return values as CVTPS2PI

Hi, I have a set of new registers for x86 which I defined in X86RegisterInfo.td to be: def POI0: X86Reg<"poi0", 0>; def POI1: X86Reg<"poi1", 1>; def POI2: X86Reg<"poi2", 2>; def POI3: X86Reg<"poi3", 3>; def POI4: X86Reg<"poi4", 4>; def POI5: X86Reg<"poi5", 5>; def POI6: X86Reg<"poi6",

Hi, I've been trying to teach LLVM that pointers are 128-bit long, which segfaults with some seemingly unrelated stacktrace when I try to take an address of a variable. Since stack saving and loading seems to work fine, I dare to assume the instruction causing problems there is leaq. Now I've done a search for leaq of the entire LLVM codebase with no success and I'd like to know which

Hi all, I've been trying to extend pointer size of the X86 target to 128 bits. For the prortype, I would like nothing more than the pointers being i128 type with the same value as before. All I've done was changing the data layout string to p:128:128 and when trying to run a basic program such as: int a = 42; int *p = &a; it segfaults with the following stack trace: #0
