I don't get this part of the plan. Where a host compiler will look for
mkoffloads?
E.g., first I configure/make/install the target gcc and corresponding mkoffload
with the following options:
--enable-accelerator=intelmic --enable-as-accelerator-for=x86_64-unknown-linux
--prefix=/install_gcc/accel_intelmic
Next I configure/make/install the host gcc with:
--enable-accelerator=intelmic --prefix=/install_gcc/host
Try using the same prefix for both.
I tried to do:
1. --enable-accelerator=intelmic
--enable-as-accelerator-for=x86_64-intelmic-linux-gnu --prefix=/install_gcc/both
2. --enable-accelerator=intelmic --prefix=/install_gcc/both
In this case only bin/x86_64-intelmic-linux-gnu-accel-intelmic-gcc from accel
compiler is saved.
All other binaries in bin, lib, lib64, libexec are replaced by host's ones.
Is there a way to have 2 working compilers and libs in the same prefix?
Sure, as long as the target triplet is different.
What I think you need to do is
For the first compiler: --enable-as-accelerator-for=x86_64-pc-linux-gnu
--target=x86_64-intelmic-linux-gnu --prefix=/somewhere
Build and install, then:
For the second: configure
--enable-offload-targets=x86_64-intelmic-linux-gnu x86_64-pc-linux-gnu
--prefix=/somewhere
No --enable-accelerator options at all. This should work, if it doesn't
let me know what you find in /somewhere after installation for both
compilers.
