I've confirmed that gcc11 is to blame by building the latest Haiku code with the gcc8 buildtools repo. Haiku boots as usual when compiled with gcc8 buildtools.
The first thing to test is likely getting a gcc11 syslibs package and updating the build-package repo with it.

I've bootstrapped haiku for riscv64 and updated our build-packages. The sifive unmatched still isn't booting with the same error.
gcc 11 introduced some major problem.

It is infinite recursion in runtime_loader.

That problem should have already been resolved by hrev55661.

Replying to waddlesplash:
That problem should have already been resolved by hrev55661.
Now it occurs in runtime_loader, not libroot.so. Jamfile is here: https://git.haiku-os.org/haiku/tree/src/system/runtime_loader/arch/riscv64/Jamfile.
comment:11 by , 3 years ago
Replying to waddlesplash:
The jamfile reuses the already-built .o from libroot.
But not for riscv64, see jamfile above. It use generic C memset, not assembly code.
comment:13 by , 3 years ago
libicu crash may be caused by incorrectly built gcc_syslibs[_devel] package. develop/headers/c++/riscv64-unknown-haiku/bits/gthr-default.h conteins stu instead of pthread implementation.
comment:14 by , 3 years ago
odd. I have https://github.com/haikuports/haikuports.cross/blob/master/sys-devel/gcc_bootstrap/gcc_bootstrap-11.2.0_2021_07_28.recipe#L185 configured for pthread.

Note that the same problem was present in gcc8 bootstrap, but older ICU was used.
comment:16 by , 3 years ago
ack. ok that makes sense. I'll dig into the ICU issue.
As a note here, we added the same no-builtin fix for arch_string in hrev55753 across all architectures. That adjusted the behavior of memset

I can confirm here my unmatched desktop is booting again after hrev55753

so.. still seeing the original crash on my unmatched even after hrev55754

Haiku riscv64 hrev55862 successfully boot in TinyEMU when downgraded ICU to icu-57.2-2.
comment:20 by , 3 years ago
| Summary: | unmatched hang - bad address → riscv64 images built with icu compiled under gcc 11.x lockup at boot |

indeed. I've pushed that as a temporary workaround in hrev56122.
The important bit seems to be that icu-57.2-2 was compiled with gcc 8.x The non-functional icu 66, icu 70 were built with gcc 11.2.0 or 11.3.0.
It seems less tied to ICU version, and more tied to gcc toolchain used.

It might be related to the recent gcc11 merge. We are still using gcc8 syslibs. Going to unbootstrap and see if new build-packages solves it.
