Subject: [PATCH 0/1] OpenRISC port
Date: Fri, 22 May 2020 20:36:32 +0900 [thread overview]
Message-ID: <20200522113633.209664-1-shorne@gmail.com> (raw)
Hi All,
This is the patch for the OpenRISC port of glibc.
DEVELOPMENT
The original patch was put together by Christian Scensson a few years ago. I
have taken the patch and finished all of the TODO items and run and fixed all of
the test failures.
BUILDING and TESTING
Testing has been done with the qemu OpenRISC simulator using the build and run
scripts found here:
- https://github.com/stffrdhrn/or1k-utils/tree/master/glibc
Running the tests I found a few issues with binutils, gcc and the OpenRISC
architecture as well, patches for binutils are upstream and gcc should be
upstream soon:
- Binutils: use latest master
- GCC: https://github.com/stffrdhrn/gcc/commits/or1k-glibc-1
- QEMU: https://github.com/stffrdhrn/qemu/commits/or1k-glibc (FPU issues)
TEST RESULTS
Pretty much all tests are passing however there are several math (fpu) tests
which are failing due to issues with setting underflow/overflow flags. These
seem consistent with issues reported by other architectures. Is there a known
issue here?
I can provide more details.
