Subject: [PATCH V2 0/2] Split tdesc_(amd64|i386)_mpx into tdesc(amd64|i386)_mpx_* and tdesc(amd64|i386)_avx_mpx_*
Date: Thu, 03 Mar 2016 17:26:00 -0000 [thread overview]
Message-ID: <1457025942-23711-1-git-send-email-walfred.tedeschi@intel.com> (raw)
CPU features can occur in any combination. The current assumption that
feature "A" implies in feature "B" does not necessarily hold.
This patch series construct an additional combination of the Intel(R)
Memory Protection Extensions (MPX) with Intel(R) Advanced Vector
Extensions (AVX).
Starting from the current implementation that has MPX combined with AVX.
A new target description having only MPX will be created using a two
step approach as described below:
First step:
Mirror (i386|amd64)mpx target descriptors onto (i386|amd64)-avx-mpx
ones.
Add a redundant target description for the MPX and AVX case using a
combined feature name to reflect that, i.e. avx-mpx. A new flag 2is
also added to address MPX case without AVX.
Second step:
Refactor (i386|amd64)-mpx target descriptors.
AVX feature is removed from the set of files that described MPX alone
feature. Present on GDB code previous to this patch.
Tests were done with hardware having MPX and AVX as is.
For MPX standing alone tests were done forcing the XCR0 bits.
Difference since V1:
* Added -api support missing as reported by Marcin.
Thanks and regards,
-Fred
Walfred Tedeschi (2):
Add redundant target descriptor for tdesc(amd64|i386)_avx_mpx_*
Re-factor (i386|amd64)mpx target descriptors.
