Thus the # correct mask corresponding to XCR0 was not present in the core file for # GDB to interrogate, resulting in the following behavior: # # [kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core # Reading symbols from testsuite/outputs/gdb.base/corefile/corefile... # [New LWP 232880] # # warning: Unexpected size of section `.reg-xstate/232880' in core file. # # With the typo fixed, the test works again as expected. # # Signed-off-by: Kevin Buettner # Fixes: 9e4636545933
