[PATCH] Decrease cortexa57_extra_costs's alu.shift_reg

From: Andrew Pinski Like I mentioned in https://gcc.gnu.org/ml/gcc/2020-01/msg00157.html, The shift by a register should be just COSTS_N_INSNS (1) rather than COSTS_N_INSNS (2). This allows lshift_cheap_p to return true now and converting switches to be using shift and other like structures. I

[PATCHv2] Add initial octeontx2 support.

From: Andrew Pinski This adds octeontx2 naming. It currently uses the cortexa57 cost model and schedule model until I submit this. This is more a place holder to get the naming of the cores in GCC 10. I will submit the cost model in the next couple of days. OK? Bootstrapped and tested on aarc

[wwwdocs] lists.html - Avoid two references to a concrete version control system (SVN here).

Already when we converted from CVS to SVN aeons ago did I work to reduce references to a concrete system. These are two further instances, now that we are moving to GIT. Committed. Gerald - Log - commit 370969e4d49ad3defb1fddaa239

RE: [PATCH] Add Optimization for various IPA parameters.

Hi Martin, This change (r280099) is causing a major performance regression on exchange2 in SPEC2017 dropping the benchmark by more than 30%. It seems the parameters no longer do anything. i.e. -flto --param ipa-cp-eval-threshold=1 --param ipa-cp-unit-growth=80 doesn't have any effect anymore.
