So I removed the 'tail' from the call and try out different properties: - IntrNoMem: memset() and the intrinsic are both optimized away as expected - IntrWriteMem: memset() optimized away by DSE but the intrinsic isn't. I would expect both to be removed, since the intrinsic is now also a dead store. - IntrReadMem: memset() and the intrinsic are both optimized away *unexpectedly* (CSE removes the intrinsic, then InstCombine removes memset). The latter is...

Hello everyone, Consider we have this following set of code: int foo() { int a,b; a = __builtin_XX(0x11); b = __builtin_XX(0x11); return a+b; } The problem currently is that LLVM eliminated the second call and copied the result from the first call into a new set of registers. Is there is a way to force LLVM to generate two explicit calls to a builtin function. The builtin takes in an integer

Hi, I was talking with aKor in #llvm how we could implement custom operation support for our ASIP architecture. We came into solution that the best way would be to write new custom operation intrinsic and optimization pass for raising certain type of function calls to those intrinsics (similar to raising mallocs). Basically our custom operation are like calls, with operand name and multiple

Hello, Julio > These later things are ignored, I don't know if when the intrinsic is > lowered, then it doesn't matter (or perhaps the reorder is made > before). What is the description of the instruction you're lowering intrinsic into? Have you looked for the instruction flags defined in Target.td file? You instruction should definitely have "isBarrier" flag set.

Hello, I have an intrinsic that matches to a asm instruction directly. This intrinsic starts a coprocessor that can do anything. If I put another instruction next to it (a multiplication for example), the "llc" reorders and puts the intrinsic after the multiplication. I have tried all: - Setting the instruction like if it takes 256 cycles or 0 cycles. - Setting the instruction with
