* Turn on -Werror=implicit-function-declaration for arm64.Elliott Hughes2015-02-211-0/+1
| | | | | | | | Implicit function declarations are much more dangerous on LP64 because sizeof(int) != sizeof(void*), so any function that returns a pointer will lose its top bits, leading to relatively hard to debug crashes. Change-Id: Ia05beffb949ca747833c2e12c40daf896f7a60a5
* Emit unique linker buildid in all binaries.Dehao Chen2015-01-151-0/+1
| | | | | | | | | | | We want to store the symbol information for all android binaries in a global database. * We ingest unstripped binaries into the global database * When we collect address data from device (e.g. instruction pointer address), we want to lookup its symbol information through the global database. The key of the mapping is a unique build id, which is the same between binaries on device (stripped) and unstripped binaries. After applying this patch, the system.img size increases by 0.0047% (16.3KB). Change-Id: Id92faf2951f43a30947e8d2b690c1af6bf7e3f54
* Disable transitive symbol resolving for arm64.Ying Wang2014-12-191-0/+3
| | | | | | | | The transitive symbol resolving causes build breakage when a binary has indirect dependency on the NDK library. We only observed such behaviour in the aarch64 toolchain. Change-Id: I29e01f16bdfa3aa206cd42d6f07c764fd436873a

| * Refactor transform-o-to-* definitions.Dan Albert2014-11-131-78/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was one generic definition for each of the transform-o-to-* functions in definitions.mk, and one target specific one in each combo/TARGET_*.mk. The generic one was entirely unused, and the target specific ones were all nearly identical. Changing anything in these functions was tedious at best, and often error prone. The differences between any 32-bit arch and its 64-bit equivalent were restricted to the name of the linker, and the ARM and MIPS definitions were identical. The few differences between ARM and x86 looked to be compatibility for an old (ca. 2008) toolchain issue with --gc-sections, and a bug (LDFLAGS coming first rather than later). To simplify things, I've moved the definitions for these out of combo/TARGET_*.mk and back into definitions.mk. The differences between ARM and x86 have been scrapped. Anything that really does still need to be target specific can be handled as I have the linker: add a TARGET_FOO variable to the given target and then add it to the generic definition.

| | | | | | | | | | | | | | | | The compiler run-time library should always be the _last_ thing linked when building static executables. This was being done correctly for libgcc, but not when using compiler-rt. Change-Id: I0689dc35f55caad2fe74c0cbb4cbe3008ded349a

| * Add option for generating coverage info.Dan Albert2014-09-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable building with coverage, the environment variable NATIVE_COVERAGE must be set to true. Set `LOCAL_NATIVE_COVERAGE := true` to generate coverage information for a given component. This is currently not supported for clang (b/17574078, b/17583330). If static library A is included in a binary B (dynamic or static executable, or shared library), and A is built with coverage information, B is required to link with libgcov.a. Since the make does not offer a good way to track this dependency, link libgcov.a even if LOCAL_NATIVE_COVERAGE is not set (but still guarded by NATIVE_COVERAGE). This ensures that all of the libgcov dependencies will always be resolved, and causes no change in the resulting binary if coverage is not used.

STL selection is done with LOCAL_CXX_STL (valid values are default, none, libc++, libc++_static, stlport, stlport_static, bionic). The selection of the STL is as follows: if LOCAL_CXX_STL == 'default' ifdef LOCAL_SDK_VERSION Use whatever STL the other NDK options have selected. else Use bionic's libstdc++ for target, GNU libstdc++ for host. This is compatible with the existing build options. endif else if LOCAL_CXX_STL == 'stlport' Use stlport. else if LOCAL_CXX_STL == 'libc++' Use libc++. else if LOCAL_CXX_STL == '' Don't use any STL. endif endif Bug: 15193147 Change-Id: If712ba0ae7908d8147a69e29da5c453a183d6540

| * Fix uses of -fPIC and -fPIE.Dan Albert2014-08-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been using -fPIC and -fPIE together in the global cflags all this time. These options are incompatible. The only reason we haven't been hit by this before is because of the forced -Bsymbolic in GCC. To fix this, pass -fpic when compiling objects for shared libraries and -fpie when compiling objects for executables. For static libraries, also use -fpic. We have to do this because static libraries might be included in either a shared library or an executable. Code compiled with -fpie cannot be included in a shared library, but code compiled with -fpic may be included in an executable. We've also been using -fpic and -fPIC together. These are different options, and only the latter will take effect. http://stackoverflow.com/a/967010 The final thing this fixes is that we had -f(PIC|PIE) flags being passed to link commands. These are compile time flags, and don't do anything at link time. Bug: 16823325 Change-Id: Ic76f47e63dc2c81b7e1a8058bae1b3dc8565d606

* | Add -latomic to all target buildsAndrew Hsieh2014-05-291-0/+5
|/ | | | | | | | | | | | | Projects using stdatomic.h needs libatomic.a in case compiler can't expand all __atomic* intrinsics. eg, __atomic_is_lock_free in armeabi/mips. Adding libatomic.a globally makes more sense than adding "LOCAL_LDLIB += -latomic " in each project including <stdatomic.h>. Projects don't need atomic operations won't get redundant DT_NEEDED entry because libatomic.a is not a shared library. Change-Id: I81dbf524544c848e667e18ab5eeabff75b5063ef

* Disable canonical prefixes of system headersAndrew Hsieh2014-05-091-0/+2
| | | | | | | | | | | | | | | | | GCC know a few pre-defined paths (relative to its location) to search for headers, libraries, program, etc. By default GCC prefixes its own path(argv[0]) and calls realpath() which result in absolute path with all symlink, . and .. removed. It's usually good to have canonicalised paths, but absolute paths in *.d file can cause unnecessary relinking when stale entries in ccache cache hit Add -no-canonical-prefixes (gcc>=4.6) and -fno-canonical-system-headers (gcc>4.6) to disable realpath() on prefixed paths Change-Id: I58d739e61fb013015fb05a9c98b2132b307f915a
