This reverts commit 05e31438ac9491cfc72c48664480796de874c860. There was quite a bit of churn with this patch, everytime related to the executable no longer being in the same directory as the shared objects. This reland ensures that all of the executables in the tests touched are in the same directory as the shared objects in the substitutions.

// First case: coverage from executable. main() is called on every code path.

// RUN: %clangxx_asan -fsanitize-coverage=func,trace-pc-guard %s -o %t.dir/exe -DFOOBAR -DMAIN

// RUN: %env_asan_opts=coverage=1:coverage_dir=%t.dir %run %t.dir/exe

// The "missing from foo" set may contain a few bogus PCs from the sanitizer
|

// FIXME %sancov GetInstrumentedPCs relies on objdump -d to
|
|
// obtain the number of instrumented PCs. The i386
|
|
// %dynamiclib has .plt entries that are not recognized by
|
|
// objdump,
|
|
// "sancov.py: found 0 instrumented PCs in *.so",
|
|
// causing AddressSanitizer-i386-linux to fail.
|
|
// Change it back to x86-target-arch after %sancov switches to a more robust approach.
|
|
|
|
// REQUIRES: x86_64-target-arch
|
|
// XFAIL: android
