Subject: [PATCH v2 0/3] OpenRISC glibc hard float support
Date: Mon, 29 Apr 2024 06:47:32 +0100 [thread overview]
Message-ID: <20240429054735.2467433-1-shorne@gmail.com> (raw)
This series adds hardware floating point support to the OpenRIS glibc port.
I will keep this cover letter short and point to patch 2/3. It contains details
about the change and testing results.
Changes since v1:
- Added combat symbols for getcontext, setcontext etc. Supporting old
mcontext_t ABI.
- Split fpu ulps file out to separate patch to make the main patch smaller.
Stafford Horne (3):
or1k: Add hard float libm-test-ulps
or1k: Add hard float support
build-many-glibcs.py: Add openrisc hard float glibc variant
