[gdb/testsuite] Allow some tests in gdb.base/restore.exp to be unsupported
We currently run into: ... 248 n = callee1 (n + l5); (gdb) PASS: gdb.base/restore.exp: caller5 calls callee1; return callee now print l1 $51 = <optimized out> (gdb) FAIL: gdb.base/restore.exp: caller5 calls callee1; return restored l1 \ to 32492 ... The problem is that we try to access the value of l1 in function caller5, but variable l1 has no DW_AT_location attribute. Since l1 is declared using the register keyword, it's valid for gcc to emit no DW_AT_location at -O0. Change the FAIL into an UNSUPPORTED. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-22 Tom de Vries <tdevries@suse.de> * gdb.base/restore.exp: Allow register variables to be optimized out at -O0.
