* Use mcpu=cortex-a57, since it is the closest to Kryo. * Clang doesn't support Kryo as a target yet. Bug: 36728278 Test: Built and booted a sailfish using Kryo. Change-Id: Ic0c9588d86fba41896e50e3f0cf0d2b310ffee93 Signed-off-by: Alex Naidis <alex.naidis@linux.com>
* Kryo is closer to Krait than to cortex-a53, so choose Krait defaults. * Made together with Jake Weinstein (xboxfanj) Bug: 36728278 Test: Built and boot sailfish set up as kryo. Change-Id: I04fa0a1dca6f97ae19202d28ee3ce8a59bf169b5 Signed-off-by: Alex Naidis <alex.naidis@linux.com>
* -mfpu=neon-fp-armv8 enables the ARMv8 floating-point and Advanced SIMD extensions. Test: Marlin builds successfully Change-Id: Ibdf71dae61b966372e3bcb946aa18d1a6cd0f8e6
Clang supports specific CPU targeting and optimization for Kryo. This switches us to using the specific Kryo targeting when Clang is used. For other compilers, we fallback to cortex-a57 targeting. Also, move the replaceFirst function to a shared location. Bug: 36728278 Test: Built and booted sailfish, ran bionic unit tests and art tests. Test: Disassembled libc.so before this change and after and looked at Test: the differences. Mostly the results were the order of instructions Test: changing. Test: Verified with the clang person (srhines) that our clang has this support Test: and that it appears to be mostly instruction scheduling changes.

Current modules must use armv7_a_neon to specify source files that compile only with neon. If a future arch variant also supports neon, all these modules will fall back to non-neon. Support a neon arch feature that modules can use instead. Similarly, support dspr2 for mips. arm_device.go was also mixing armv7-a-neon with armv7_a_neon. Use armv7-a-neon consistently, and fix the - to _ when creating the property structs. Test: m -j checkbuild Change-Id: I24d3764280ab3bcbb9a73c0934edc9b99fc7f6a0
Also, update flags for cortex-a53. Bug: 37647380 Test: Built target with cortex-a73 for both 32 bit/64 bit. Test: Built target with cortex-a53.cortex-a57 for both 32 bit/64 bit. Test: Ran bionic unit tests, ran art target tests. (cherry picked from commit 1d9aa26) Change-Id: I3325f60add7f424f8cca53c22919fc481ef5e787
