From 612dd6c26274d7183b21d38120bc98c45dcf2736 Mon Sep 17 00:00:00 2001 From: Rahul Chaudhry Date: Fri, 27 Feb 2015 10:46:42 -0800 Subject: [PATCH] build: run cgo tests with -pie if the external linker supports it. PIE binaries can be built by the Go compiler in external link mode with extldflags="-pie". These binaries support ASLR (address space layout randomization) when executed on systems with appropriate kernel/dynamic linker support. This CL enables some cgo tests to run with -pie as a sanity check (in addition to the other linker flag combinations they already test). I have tested this functionality more thoroughly by building the full compiler testsuite (test/...) and standard library tests with -pie and executing them remotely on ChromeOS devices for all three linux architectures (linux_amd64, linux_386, and linux_arm).
