From ef46e101be0afb84898a9ac37af1f1f6c1677cf4 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Thu, 20 Feb 2020 13:44:11 +0000 Subject: Do not verify dex files for --compiler-filter=assume-verified. Reduces the compilation time for the boot image extension with said filter by over 0.5s (comparing the best observed timing "before" to the worst observed timing "after"). Test: aosp_taimen-userdebug boots; adb root && \ adb shell stop && \ adb shell setprop dalvik.vm.boot-image \ 'boot.art:/nonx/boot-framework.art!/system/etc/boot-image.prof' && \ adb shell 'setprop dalvik.vm.extra-opts \ "-Ximage-compiler-option --compiler-filter=assume-verified"' && \ adb shell start # Starts correctly # Check dex2oat timing in logcat Bug: 119800099 Change-Id: I3fc82c9485385ff5e0ccc5031e1141a685ee6c19 --- compiler/driver/compiler_options.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'compiler/driver/compiler_options.h') diff --git a/compiler/driver/compiler_options.h b/compiler/driver/compiler_options.h index c05ff89beb..747205e4e5 100644 --- a/compiler/driver/compiler_options.h +++ b/compiler/driver/compiler_options.h @@ -103,6 +103,10 @@ class CompilerOptions final { return CompilerFilter::IsVerificationEnabled(compiler_filter_); } + bool AssumeDexFilesAreVerified() const { + return compiler_filter_ == CompilerFilter::kAssumeVerified; + } + bool AssumeClassesAreVerified() const { return compiler_filter_ == CompilerFilter::kAssumeVerified; } -- cgit v1.2.3-59-g8ed1b
