Subject: [PATCH 0/2] Add AVX512-FP16 support.
Date: Thu, 29 Jul 2021 10:38:31 +0200 [thread overview]
Message-ID: <20210729083833.2483704-1-felix.willgerodt@intel.com> (raw)
New CPUs will add support for the FP16 data type in AVX512:
https://software.intel.com/content/www/us/en/develop/download/intel-avx512-fp16-architecture-specification.html
This comes with ABI changes that allow _Float16 and _Float16 _Complex as
function arguments and return values.
This series adds support for the register view and ABI changes.
Regards,
Felix
Felix Willgerodt (2):
Add half support for AVX512 register view.
gdb: Enable finish command and inferior calls for _Float16 on amd64
and i386.
