- Authentication-results: sourceware.org; auth=none
Hi all,
I've addressed the suggestions provided by Pedro Alves. Meanwhile, AVX-512
support has been committed in gcc mainline, see News on http://gcc.gnu.org/
for details.
Mark, I'm looking forward to your feedback on the patch - ideally the
approval to commit.
Thanks and Regards,
Michael
This patch series adds support for the Intel(R) Advanced Vector Extensions 512
(Intel(R) AVX-512) registers. Native and remote debugging are covered by this
patch series.
Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers
in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available
registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower
256-bits of the ZMM registers are aliased to the respective 256-bit YMM
registers. The lower 128-bits are aliased to the respective 128-bit XMM
registers.
There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode
and 64-bit mode.

Changes between V1 and V2:
* Following feedback by Pedro Alves, i386-avx512.exp no using
gdb_test_multiple when checking if AVX512 is supported by the
CPU. If CPU does not support AVX512, return unsupported.
Simplified test as timeout is handled by framework. Added newline
at the end of file.
Note:
* Documentation patch already approved by Eli.
