Hi all, Is there any ongoing work in LLVM/Clang to support fixed-point arithmetic as described in ISO/IEC TR 18037 ? It seems that gcc has support for it since 2007 and it would be useful for us to add such support. Just to get an idea if we decide to work on this, how long would it take to get it implemented ? Regards, Ivan

Hi, How can I get the llvm-type of the formal argument while lowering it ? My target needs to map pointer and non-pointer parameters to different registers. In addition, parameter lowering is address space dependent (another reason why I need such information). Looking at the DAGBuilder, I found that it is dropping it when translating llvm-types to BE types. Even if the base type is saved

If you need llvm::Argument, this returns the iterator pointing to the first argument: Function::const_arg_iterator Arg = DAG.getMachineFunction().getFunction()->arg_begin(); On Wed, Mar 14, 2012 at 8:16 AM, Ivan Llopard <ivanllopard at gmail.com> wrote: > Hi, > > How can I get the llvm-type of the formal argument while lowering it ? > > My target needs to map pointer and non-pointer parameters to different > registers.

Hi, I'm facing a problem in my BE while trying to remove certain copies. Here is a code snippet which I would like to optimize %vreg1<def> = READF32r; vRRegs:%vreg1 %vreg2<def> = COPY %vreg1:rsub_h; iRSubRegs:%vreg2 vRRegs:%vreg1 %vreg3<def> = COPY %vreg1:rsub_l; iRSubRegs:%vreg3 vRRegs:%vreg1 This code produces subreg-to-subreg copies but I would like to have direct
