Add minimal-runtime support for integer overflows. Adds Make support for -fsanitze-minimal-runtime when using the integer overflow sanitizers. This makes the crashes due to these sanitizers less mysterious. This also cleans up the handling of the integer_overflow flag. Bug: 64091660 Test: Compiled and checked the generated compiler commands Test: Checked program that overflows for the abort reason Test: Checked integer_overflow flag still emits overflow checks Change-Id: I11012ed0cbbf51935f549a08bd17109b5ce6f330
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
