Subject: [PATCH 1/2] Add half support for AVX512 register view.
Date: Thu, 29 Jul 2021 10:38:32 +0200 [thread overview]
Message-ID: <20210729083833.2483704-2-felix.willgerodt@intel.com> (raw)
In-Reply-To: <20210729083833.2483704-1-felix.willgerodt@intel.com>
This adds support for the half datatype, FP16, to the AVX512 register printing.
gdb/ChangeLog:
2020-07-21 Felix Willgerodt <Felix.Willgerodt@intel.com>
* i386-tdep.c (i386_zmm_type) <v32_half>: New field.
(i386_ymm_type) <v16_half>: New field.
(i386_gdbarch_init): Add set_gdbarch_half_format.
* features/i386/64bit-avx512.xml: Add half type.
* features/i386/64bit-avx512.c: Regenerated.
* features/i386/64bit-sse.xml: Add half type.
* features/i386/64bit-sse.c: Regenerated.
gdb/testsuite/ChangeLog:
2021-07-21 Felix Willgerodt <Felix.Willgerodt@intel.com>
* gdb.arch/x86-avx512fp16.c: New file.
* gdb.arch/x86-avx512fp16.exp: New file.
* lib/gdb.exp (skip_avx512fp16_tests): New function.
