* Enable -fstack-protector-strong for arm.Elliott Hughes2017-03-141-1/+1
| | | | | | | | | | | | | | | | | | | This results in nearly all functions with the possibility of stack corruption getting stack canaries, because it applies to any function taking a reference to the frame or with a local array rather than just the functions with arrays larger than 8 bytes. It was developed for use in Chrome (and Chrome OS) and has also been adopted by various other distributions (Arch, Fedora, Ubuntu, etc). The code size increase ranges from ~1.5% to ~2.5%, compared to ~0.3% to ~0.7% with the more conservative switch. The increase in the performance loss is usually minimal. The overall size increase once everything other than C and C++ code is taken into account is minimal, and it greatly improves the mitigation of stack buffer overflow vulnerabilities. https://lwn.net/Articles/584225/ Change-Id: Iccc20852db8a5e4dd9792f9da6d5e325fc59b0a5

* Apply correct, optimized mfpu compiler flag for ARMv7-A Cortex CPUsarter972015-10-271-7/+6
| | | | | | | | | | | | | | | | | For those ARMv7-A Cortex CPUs that can handle VFPv4 floating point, We can set "-mfpu=neon-vfpv4" instead of generic "-mfpu=neon" to gain extra performance improvements.

* build: Enable custom ccache cache dir for AndroidMatt Mower2015-10-091-0/+6
| | | | | | | | | | | | During lunch, check environment variables for ANDROID_CCACHE_DIR. If it is specified, CCACHE_DIR is set to match. Prevents issues with multiple versions of ccache writing to the same cache dir. ANDROID_CCACHE_SIZE should also be specified, allowing for a distinct cache directory size from the default. Syntax for ANDROID_CCACHE_SIZE is the same as applied in the command: 'ccache -M$ANDROID_CCACHE_SIZE' Change-Id: I17497a6f56347850e0fa7b8ebd4de0b5a0b13e55

* Fix OSX support for new CLI Tools (starting with 7.1)Brian Chu2015-10-072-0/+12
| | | | | | | | To build on OSX with late-2015 CLI Tools, the build system must include C++ headers from a new location. Mid-2015 CLI Tools and older can still be used, so the older location will also be kept. Change-Id: I422d28cb41ab57fcc816538a822df8aecdf7d9d6
* Add support for OSX up to 10.10 and CLI ToolsBrian Chu2015-10-061-3/+18
| | | | | | | | | | | | | | | | - Support using OSX versions 10.9 and 10.10 as the compilation host. Please note that the prebuilt darwin-x86 gcc is missing an upstream patch that properly identifies 10.10 as newer than 10.2, which restricts mac_sdk_versions_supported to 10.9. - Support using Xcode Command Line Tools, waiving the requirement for installing the full Xcode development suite for 600k worth of C++ headers. These build modifications have been verified by successfully compiling a cm12-hammerhead image from scratch on a OSX Yosemite 10.10.1 host with Xcode Command Line Tools 6.1.1 installed.

* Fix file-size stats on OSXKoushik Dutta2015-10-061-1/+6
| | | | | | | | | | | | | | Kernel makefiles that the stat on the system is GNU stat. GNU stat uses the "-c" option to specify format. Darwin stat uses the "-f" option to specify format. This discrepency will cause kernel build breaks. On my system, I symlink stat to GNU stat. This causes the "get-file-size" define to fail. The fix for this is to detect "gstat", aka GNU stat, and use that appropriately. Change-Id: I987c155b7dc3ff14ffe6da40edf834ca34b7df75 Fix up the get-file-size function that was broken due to the prior commit that made it utilize gnu stat (gstat) Change-Id: I24bba2bfcb509ad1ad76d2260eedd685ba45c393

* Add $ORIGIN/lib[64] to host binary's rpath.Ying Wang2015-06-011-0/+2

This workaround enables them to work in the exsiting SDK directory structure. Bug: 21301578 Change-Id: Ibebfbfb8b30e81e7bbaf13a21bb205f3f0282d24

Explicitly not added in this change is FORTIFY_SOURCE=2. Adding that option turns on glibc's warn_unused_result attributes. This generates a huge number of new compile time warnings, and for the multiple makefiles which have -Werror in them, turns those warnings into errors. I'm not able to fix all the errors right away.
