search for: ty2

Hello, in some operations there is a ty2 type, for example in truncate. What is the most right way to get it ? I have seen some EVT types, but this is connected to DAG... and I don't believe that there is no easy way to get ty2 with one call function. -------------- next part -------------- An HTML attachment was scrubbed...

Hi, >From http://llvm.org/docs/LangRef.html#bitcast-to-instruction: The 'bitcast' instruction converts value to type ty2. It is always a no-op cast because no bits change with this conversion. The conversion is done as if the value had been stored to memory and read back as type ty2. Pointer (or vector of pointers) types may only be converted to other pointer (or vector of pointers) types with this instruction if the...

Hi, I noticed many functions in the TargetTransformInfo interface are duplicates of those already in TargetLowering (e.g. isTruncateFree). Is the expectation really that targets will reimplement the same functions twice? AArch64’s TTI uses some TLI calls in some of its implementations, but why doesn’t the base TargetTransformInfo call the TargetLowering versions by default? - Matt

...shufflevector through memory on systems where little-Endian mode is relevant, see http://llvm.org/devmtg/2014-10/Slides/Schmidt-SupportingVectorProgramming.pdf). Given what's been done, should we update the LangRef. It currently reads, " The ‘ bitcast ‘ instruction converts value to type ty2 . It is always a no-op cast because no bits change with this conversion. The conversion is done as if the value had been stored to memory and read back as type ty2 ." But this is now, at the least, misleading, because this process of storing the value as one type and reading it back in as anot...

Hi, > "It is always a no-op cast because no bits change with this conversion. The conversion is done as if the value had been stored to memory and read back as type ty2." I think a simple "as-if" in there should be sufficient; "It is always a no-op cast because it acts as if no bits change with this conversion. The conversion is done as if the value had been stored to memory and read back as type ty2." What do you think? James On Thu,...
