-- Added TARGET_PREFER_32_BIT, which sets LOCAL_32_BIT_ONLY for an executable, if LOCAL_NO_2ND_ARCH is not true. Name resolving in 64-bit multilib build: -- Name resolving in PRODUCT_PACKAGES: foo:32 resolves to foo_32; foo:64 resolves to foo; foo resolves to both foo and foo_32 (if foo_32 is defined). -- Name resolving for LOCAL_REQUIRED_MODULES: If a module is built for 2nd arch, its required module resolves to 32-bit variant, if it exits; Otherwise for executable and shared library, a required module resolves to the default 64-bit variant; for other module classes, required module foo resolves to both foo and foo_32 (if foo_32 is defined) Bug: 12898862 Change-Id: I5fda1a77f58814097b10b5ad2743ee25adfaecc4
