Subject: [PATCH] Update helgrind and drd suppression libc and libpthread paths
|
in glibc 2.34
|
|
glibc 2.34 moved all pthread functions into the main libc library.
|
And it changed the (in memory) path of the main libc library to
|
libc.so.6 (before it was libc-2.xx.so).
|
|
This breaks various standard suppressions for helgrind and drd.
|
Fix this by doing a configure check for whether we are using glibc
|
2.34 by checking whether pthread_create is in libc instead of in
|
libpthread. If we are using glibc then define GLIBC_LIBC_PATH and
|
GLIBC_LIBPTHREAD_PATH variables that point to the (regexp) path
|
of the library that contains all libc functions and pthread functions
|
(which will be the same path for glibc 2.34+).
|
|
Rename glibc-2.34567-NPTL-helgrind.supp to glibc-2.X-helgrind.supp.in
|
and glibc-2.X-drd.supp to glibc-2.X-drd.supp.in and replace the
|
GLIBC_LIBC_PATH and GLIBC_LIBPTHREAD_PATH at configure time.
|
|
The same could be done for the glibc-2.X.supp.in file, but hasn't
|
yet because it looks like most suppressions in that file are obsolete.
|

+# These are very ugly. They are needed to suppress errors inside (eg)
|
+# NPTL's pthread_cond_signal. Why only one stack frame -- at least we
|
+# should see the wrapper calling the real functions, right?
|
+# Unfortunately, no: the real functions are handwritten assembly (in
|
+# the glibc-2.5 sources) and does not create a proper stack frame.
|
+# Therefore it's only one level of unwinding before we're back out in
|
+# user code rather than the 2 levels you'd expect.
