If you provided some relative path to the shared library, such as with |
|
export LD_LIBRARY_PATH=. |
|
then gdb would fail to match the shared library name during the TLS lookup. |
|
|
|
|
|
Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed? |
|
|
|
|
|
The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'. |
|
The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'. |

* solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute |
|
requested pathnames to the internal loaded relative pathnames. |
