From 1b9b7d539335030e3d269a57d418a4fa6d62c038 Mon Sep 17 00:00:00 2001 From: Mike Klein Date: Tue, 27 Feb 2018 10:37:40 -0500 Subject: 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.
