Hello!
Older glibcs (CentOS 2.5) have specialized extern inline functions
defined in stdlib.h that interfere with ASANs testcases in
g++.dg/asan:
#ifdef __USE_EXTERN_INLINES
/* Define inline functions which call the internal entry points. */
...
These cause many strtol, strtoll and atoi runtime failures with
asan_test.C and interception-malloc-test-1.C, and build failures
(redefinition of strtol) for the other interception tests.
Patch avoids this unwanted inlining ba declaring __NO_INLINE__ for
linux targets.
2013-02-09 Uros Bizjak <ubiz...@gmail.com>
* g++.dg/asan/asan_test.C: Compile with -D__NO_INLINE__
for *-*-linux* targets.
* g++.dg/asan/interception-test-1.c: Ditto.
* g++.dg/asan/interception-failure-test-1.C: Ditto.
* g++.dg/asan/interception-malloc-test-1.C: Ditto.
Patch was tested on x86_64-pc-linux-gnu {,-m32} CentOS 5.9 (where it
fixes several runtime and build failures) and Fedora 17.
OK for mainline?
Uros.
