## Compiling the HIP source into assembly
Using HIP flags `-c -S` will help generate the host x86_64 and the device AMDGCN assembly code when paired with `--cuda-host-only` and `--cuda-device-only` respectively. In this sample we use these commands:
```
/opt/rocm/hip/bin/hipcc -c -S --cuda-host-only -target x86_64-linux-gnu -o square_host.s square.cpp

## Compiling the assembly into a valid HIP executable
If valid, the modified host and device assembly may be compiled into a HIP executable. The host assembly can be compiled into an object using this command:
```
/opt/rocm/hip/bin/hipcc -c square_host.s -o square_host.o
<ROCM_PATH>/hip/bin/hipcc -c square_host.s -o square_host.o
```
However, the device assembly code will require a few extra steps. The device assemblies needs to be compiled into device objects, then offload-bundled into a HIP fat binary using the clang-offload-bundler, then llvm-mc embeds the binary inside of a host object using the MC directives provided in `hip_obj_gen.mcin`. The output is a host object with an embedded device object. Here are the steps for device side compilation into an object:
```
/opt/rocm/hip/../llvm/bin/clang -target amdgcn-amd-amdhsa -mcpu=gfx900 square-hip-amdgcn-amd-amdhsa-gfx900.s -o square-hip-amdgcn-amd-amdhsa-gfx900.o

<ROCM_PATH>/hip/../llvm/bin/clang -target amdgcn-amd-amdhsa -mcpu=gfx906 square-hip-amdgcn-amd-amdhsa-gfx906.s -o square-hip-amdgcn-amd-amdhsa-gfx906.o

<ROCM_PATH>/llvm/bin/llvm-mc -triple x86_64-unknown-linux-gnu hip_obj_gen.mcin -o square_device.o --filetype=obj
```
**Note:** Using option `-bundle-align=4096` only works on ROCm 4.0 and newer compilers. Also, the architecture must match the same arch as when compiling to assembly.
Finally, using the system linker, hipcc, or clang, link the host and device objects into an executable:
```
/opt/rocm/hip/bin/hipcc square_host.o square_device.o -o square_asm.out
<ROCM_PATH>/hip/bin/hipcc square_host.o square_device.o -o square_asm.out
```
If you haven't modified the GPU archs, this executable should run on both `gfx900` and `gfx906`.

To transform the LLVM bitcode into human readable LLVM IR, use these commands:
```
/opt/rocm/llvm/bin/llvm-dis square-hip-amdgcn-amd-amdhsa-gfx900.bc -o square-hip-amdgcn-amd-amdhsa-gfx900.ll
/opt/rocm/llvm/bin/llvm-dis square-hip-amdgcn-amd-amdhsa-gfx906.bc -o square-hip-amdgcn-amd-amdhsa-gfx906.ll
<ROCM_PATH>/llvm/bin/llvm-dis square-hip-amdgcn-amd-amdhsa-gfx900.bc -o square-hip-amdgcn-amd-amdhsa-gfx900.ll
<ROCM_PATH>/llvm/bin/llvm-dis square-hip-amdgcn-amd-amdhsa-gfx906.bc -o square-hip-amdgcn-amd-amdhsa-gfx906.ll
```
**Warning:** We cannot ensure any compiler besides the ROCm hipcc and clang will be compatible with this process. Also, there is no guarantee that the starting IR produced with `-x cl` will run with HIP runtime. Experimenting with other compilers or starting IR will be the responsibility of the developer.

## Compiling the LLVM IR into a valid HIP executable
If valid, the modified host and device IR may be compiled into a HIP executable. First, the readable IR must be compiled back in LLVM bitcode. The host IR can be compiled into an object using this command:
```
/opt/rocm/llvm/bin/llvm-as square_host.ll -o square_host.bc
/opt/rocm/hip/bin/hipcc -c square_host.bc -o square_host.o
<ROCM_PATH>/llvm/bin/llvm-as square_host.ll -o square_host.bc
<ROCM_PATH>/hip/bin/hipcc -c square_host.bc -o square_host.o
```
However, the device IR will require a few extra steps. The device bitcodes needs to be compiled into device objects, then offload-bundled into a HIP fat binary using the clang-offload-bundler, then llvm-mc embeds the binary inside of a host object using the MC directives provided in `hip_obj_gen.mcin`. The output is a host object with an embedded device object. Here are the steps for device side compilation into an object:
```
/opt/rocm/hip/../llvm/bin/llvm-as square-hip-amdgcn-amd-amdhsa-gfx900.ll -o square-hip-amdgcn-amd-amdhsa-gfx900.bc
/opt/rocm/hip/../llvm/bin/llvm-as square-hip-amdgcn-amd-amdhsa-gfx906.ll -o square-hip-amdgcn-amd-amdhsa-gfx906.bc

<ROCM_PATH>/llvm/bin/llvm-mc hip_obj_gen.mcin -o square_device.o --filetype=obj
```
**Note:** Using option `-bundle-align=4096` only works on ROCm 4.0 and newer compilers. Also, the architecture must match the same arch as when compiling to LLVM IR.
Finally, using the system linker, hipcc, or clang, link the host and device objects into an executable:
```
/opt/rocm/hip/bin/hipcc square_host.o square_device.o -o square_ir.out
<ROCM_PATH>/hip/bin/hipcc square_host.o square_device.o -o square_ir.out
```
If you haven't modified the GPU archs, this executable should run on both `gfx900` and `gfx906`.
