From patchwork Mon Nov 5 07:33:01 2012 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [i386] : AMD bdver3 enablement From: "Gopalasubramanian, Ganesh" X-Patchwork-Id: 197155 Message-Id: To: "gcc-patches@gcc.gnu.org" Cc: Uros Bizjak Date: Mon, 5 Nov 2012 07:33:01 +0000 Couple of changes done with respect to the review comments. 1. sseshuf type attribute is handled in unit attribute calculation. 2. sseadd1 instruction attribute is handled in the new scheduler descriptions. The patch is attached as (patch.txt). The new file (bdver3.md) describing the pipelines is also attached. Bootstrapping and "make -k check" passes. OK for upstream?

Please handle new sseshuf type attribute in various attribute calculations. You should at least add it to unit attribute calculation, but please review other calculations. This attribute replaces sselog, so probably all places that mention sselog needs to be updated. > A new file (bdver3.md) is also attached which describes the pipelines. Please note recent addition - sseadd1, similar to sseadd. You should handle this and other _1 types in a similar way. _1 types only mark instructions that do not have operand2, but are otherwise the same as instructions without prefix. > 2012-10-11 Ganesh Gopalasubramanian > > > bdver3 Enablement > * gcc/doc/extend.texi: Add details about bdver3. > * gcc/doc/invoke.texi: Add details about bdver3. > * config.gcc (i[34567]86-*-linux* | ...): Add bdver3. > (case ${target}): Add bdver3. > * config/i386/i386.h (TARGET_BDVER3): New definition. > * config/i386/i386.md (define_attr "cpu"): Add bdver3. > * config/i386/cpuid.h (bit_XSAVEOPT): New field for > getting the xsaveopt cpuid flag.
