Add test for global variable that is nested by another DSO This is just a testcase addition that I am proposing for upstream GDB. We have this in our internal tree, and the related RH bug is: <https://bugzilla.redhat.com/show_bug.cgi?id=809179> (You might not be able to see all the comments without privileges.) This bug is about a global variable that got incorrectly displayed by GDB. This bug has already been fixed a long time ago by Joel's commit: commit 19630284f570790ebf6d50bfb43caa1f125ee88a Author: Joel Brobecker <brobecker@gnat.com> Date: Tue Jun 5 13:50:50 2012 +0000 But I think a testcase for it wouldn't hurt. So, consider the following scenario: $ cat solib1.c int test; void c_main (void) { test = 42; } $ cat solib2.c int test; void b_main (void) { test = 42; } $ cat main.c int main (int argc, char *argv[]) { c_main (); b_main (); return 0; } $ gcc -g -fPIC -shared -o libSO1.so -c solib1.c $ gcc -g -fPIC -shared -o libSO2.so -c solib2.c $ gcc -g -o main -L$PWD -lSO1 -lSO2 main.c $ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main ... $1 = 0 This happened with GDB before Joel's commit above. Now, things work and GDB is able to correctly display the nested global variable: $ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main ... $1 = 42 The testcase attached tests this behavior. gdb/testsuite/ChangeLog: 2014-09-16 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.base/global-var-nested-by-dso-solib1.c: New file. * gdb.base/global-var-nested-by-dso-solib2.c: Likewise. * gdb.base/global-var-nested-by-dso.c: Likewise. * gdb.base/global-var-nested-by-dso.exp: Likewise.
