How to compile to HSACO about hcc HOT 3 CLOSED

Hi,
Currently, there is no command line option to dump code object from HCC.
The work around is setting env variables KMDUMPISA or KMDUMPLLVM[1] to 1. Which dumps ISA and LLVM IR respectively. Once you get the ISA, you can use clang(4.0) or llvm-mc and clang shipped with ROCm to generate code object. I wrote a sample which generates code object from LLVM IR and ISA [2]. Hope it'll be useful.

This is not recommended as it is not the intended way of generating ISA.

The new developer-preview branch on HIP can now generates code object from kernel using hipcc. You can checkout vector copy sample here [3]. Although the sample is HIP kernel, you can try writing kernel in HCC.

Thanks! That was very helpful. I'll try the HIP method.

HIP is probably best supported flow for this right now but we are also providing some tools so you can do this a pure HCC environment, if desired. See this checkin:

You need to generate a full linked executable (not just object files) but then can use the tool above to extract all of the "code objects".
