This patch makes a further attempt to fix the tests broken by the previous revision by ensuring that the command line for the modified Dexter tests use -std=gnu++11, in keeping with the old build script. This reverts commit 5647f2908de90fe07b0805e988cd2e91a1751928.

// Purpose:
|
|
// This ensures that DW_OP_deref is inserted when necessary, such as when
|
|
// NRVO of a string object occurs in C++.
|
|
//
|
|
// REQUIRES: !asan, compiler-rt, lldb
|
|
// UNSUPPORTED: system-windows
|
|
// Zorg configures the ASAN stage2 bots to not build the asan
|
|
// compiler-rt. Only run this test on non-asanified configurations.
