According to yesterday's patch https://github.com/dotnet/runtime/pull/127392/changes#diff-0ed6f3997357a6ff6652a7509482b05370b67e8e3041eecfd89f9556e7b59313R495 -pie should work on Haiku, -fPIE was supposed to be replaced with -fPIC for executables. What was the error? I think you want to keep -Wl,-pie and -Wl,-no-pie (linker options) and separate out -pie if compiler is complaining.

I don't have the exact error here, but it had something to do with -fPIE not working with -shared.

-shared should be passed by default by the toolchain since all Haiku executables are built as shared objects for some reason.

Ok, during the build, it should've published crossgen2 and ilc binaries as AOT. You can copy them from published directory on Haiku machine and run <path> --help, if it prints help without any error, we are good here.

I guess I'm waiting for the other PRs (especially the approved ones) to get merged before continuing. Right now I'm running it on disposable GitHub Actions machines and it's becoming cherry-pick hell.

Yes, this is fine, you can ignore that test. Those tests are specifically publishing with explicit <IlcInstructionSet> option. The default is SSE4.2 which covers all x64 machines manufactured since 2008. We can set <IlcInstructionSet>native</IlcInstructionSet> in csproj if aim is to run app on the same machine.

It seems a bit suspicious though, since I ran this on a i7-1165G7, which should support AVX-512 according to Intel.

According to GDB it is due to this returning 0:

runtime/src/native/minipal/cpufeatures.c

Lines 148 to 155 in 9806aba

uint32_t eax;
__asm(" xgetbv\n" \
: "=a"(eax) /*output in eax*/\
: "c"(0) /*inputs - 0 in ecx*/\
: "edx" /* registers that are clobbered*/
);
// check OS has enabled XMM, YMM and ZMM state support
return ((eax & 0xE6) == 0x0E6) ? 1 : 0;

So it's a Haiku issue, not an issue with this PR.

So should this be in sync with what was done in #127392 ?

I am pretty sure -pic is a no-op in Haiku since any binary (including executables) can be loaded at any address.

From the LLVM project, on Haiku:

  1. -pic is the default and always passed:

https://github.com/llvm/llvm-project/blob/652700b4cb3c87294f2d78cb87df5e394e589984/clang/lib/Driver/ToolChains/Haiku.h#L48

  1. -pie is swallowed by the driver (and therefore is a no-op):

https://github.com/llvm/llvm-project/blob/652700b4cb3c87294f2d78cb87df5e394e589984/clang/lib/Driver/ToolChains/Haiku.cpp#L43

  1. The driver for Haiku also unconditionally passes -shared:

https://github.com/llvm/llvm-project/blob/652700b4cb3c87294f2d78cb87df5e394e589984/clang/lib/Driver/ToolChains/Haiku.cpp#L60

  1. The linker errors out when it sees both -pie and -shared:

https://github.com/llvm/llvm-project/blob/652700b4cb3c87294f2d78cb87df5e394e589984/lld/ELF/Driver.cpp#L404

Therefore, replacing -fPIE with -fPIC (or passing -fPIC at all) on Haiku is redundant. If synchronization between this and #127392 is mandatory, I believe we should change the other file to not pass anything for Haiku targets instead.

Yup, I think @jkotas point is to keep them in sync so it can be reasoned about. If it works without those flags, then omitting on both sides sounds good. We can validate build.sh clr+libs --os haiku --cross --bootstrap with and without -gcc (it publishes crossgen2/ilc and other stuff which you can copy to vm and run --help as before to make sure binaries are executing).

Well, with the argument, it works without -gcc.

With -gcc, it fails before even calling the linker:

I think you can ignore gcc error. We support clang or gcc for "host=target" and host clang and gcc with sysroot for cross / "host!=target". In case of haiku (and illumos), we are using gcc from sysroot built for host, it's different than using host gcc with target=<rootfs toolchain>. Unless you see people using this setup in wild, we don't support it as it stands.

Ah, it's actually more simpler, we don't support cross (when target!=host) PublishAot with gcc, period. 😅
