Reland "Reland "make SkJumper stages normal Skia code"" This is a reland of 78cb579f33943421afc8423a39867fcfd69fed44 This time, lowp stages are controlled by !defined(JUMPER_IS_SCALAR), not by defined(__clang__). The two are usually the same, except when we opt Clang builds into JUMPER_IS_SCALAR artificially. Some Google3 builds use compilers old enough that they barf when compiling our NEON code. It's conceivably also possible to define JUMPER_IS_SCALAR yourself, but I don't think anyone does that.

I will put this back in a follow up. > > > > I have had to drop Windows down to __vectorcall and our narrower > > stage calling convention that keeps the d-registers on the stack. > > I tried forcing sysv_abi, but that crashed Clang. :/ > > > > Added a TODO to up the same narrower stage calling convention > > for lowp stages... we just *don't* today, for no good reason. > > > > Change-Id: Iaaa792ffe4deab3508d2dc5d0008c163c24b3383 > > Reviewed-on: https://skia-review.googlesource.com/110641 > > Commit-Queue: Mike Klein <mtklein@chromium.org> > > Reviewed-by: Herb Derby <herb@google.com> > > Reviewed-by: Florin Malita <fmalita@chromium.org> > > Change-Id: I44f2c03d33958e3807747e40904b6351957dd448 > Reviewed-on: https://skia-review.googlesource.com/112742 > Reviewed-by: Mike Klein <mtklein@chromium.org> Change-Id: I3d71197d4bbb19ca4a94961a97fa2e54d5cbfb0d Reviewed-on: https://skia-review.googlesource.com/112744 Reviewed-by: Mike Klein <mtklein@google.com> Commit-Queue: Mike Klein <mtklein@google.com>
