| * PR10491 Don't assign to REG_IP if it isn't an lvalue (s390 and ia64).Mark Wielaard2009-08-062-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To fixup REG_IP to show the correct value after a [ku]probe trap we assigned the address of the actual instruction pointer of the probed instruction. That doesn't work on architectures, s390 and ia64, where REG_IP is not a simple lvalue. Just don't try to fixup the address in those cases. If this isn't enough, the uprobe_stmt_num.exp testcase will point this out. * runtime/regs.h: Define REG_IP_LVALUE for x86_64, i386, powerpc64 and arm. * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Only fixup REG_IP when REG_IP_LVALUE is defined.

| * Remove as_root calls from the printf testsuiteJosh Stone2009-08-055-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | Once upon a time, we would use sudo staprun, and so output files from "-o" were owned by root. For a while now we've used a setuid staprun instead, and the output files are created by stapio as the user. Thus, we don't need as_root to remove those files anymore. * testsuite/systemtap.printf/end1b.exp: Clean up without as_root. * testsuite/systemtap.printf/mixed_outb.exp: Ditto. * testsuite/systemtap.printf/out1b.exp: Ditto. * testsuite/systemtap.printf/out2b.exp: Ditto. * testsuite/systemtap.printf/out3b.exp: Ditto.
| * Don't spawn uprobes tests with sudoJosh Stone2009-08-055-14/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using spawn with sudo doesn't work well, because the password prompt won't go to the correct TTY. The only reason that the uprobes tests needed to do this is so uprobes.ko could be built as root. Now instead, I've added a pre-check that will directly call the uprobes make with sudo (via the as_root proc). * testsuite/lib/systemtap.exp (uprobes_p): Check and build uprobes.ko. * testsuite/systemtap.base/uprobes.exp: Use uprobes_p; don't spawn sudo. * testsuite/systemtap.base/bz6850.exp: Ditto. * testsuite/systemtap.base/bz10078.exp: Ditto. * testsuite/systemtap.base/bz6905.exp: sudo isn't needed for -p2.

| | | | | | | | | | | | | | | | | | | | | | | | I noticed that most uses of update_visitor::require() were simply writing the value back to the same place, i.e. foo = require(foo). The new replace() method just encapsulates that paradigm, so we don't have the duplication between the LHS and RHS. * staptree.h (update_visitor::replace): New. * elaborate.cxx, staptree.cxx, tapset-mark.cxx, tapset-perfmon.cxx, tapset-procfs.cxx, tapset-utrace.cxx, tapsets.cxx: Update all require calls that are simply updating the value in-place.

Note that loc2c won't allow this for noncontiguous arrays, as the access methods need to be statically computed, but for contiguous arrays and pointers-as-arrays it works just fine. * staptree.h (target_symbol::component): Add expression_array_index. * staptree.cxx (target_symbol::visit_components): New helper.

| | * Unify no-component assertions on target variablesJosh Stone2009-07-317-131/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several tapsets that can't deal with component dereferences on their target variables, and they all check-and-throw in the same way. This refactors the checks into a target_symbol member. * staptree.cxx (target_symbol::assert_no_components): New. * tapsets.cxx (tracepoint_var_expanding_visitor::visit_target_symbol_arg, tracepoint_var_expanding_visitor::visit_target_symbol_context): Use the new assertion function to check for no components. * tapset-mark.cxx (mark_var_expanding_visitor::visit_target_symbol_arg, mark_var_expanding_visitor::visit_target_symbol_context): Ditto. * tapset-perfmon.cxx (perfmon_var_expanding_visitor::visit_target_symbol): Ditto. * tapset-procfs.cxx (procfs_var_expanding_visitor::visit_target_symbol): Ditto. * tapset-utrace.cxx (utrace_var_expanding_visitor::visit_target_symbol_arg, utrace_var_expanding_visitor::visit_target_symbol_context): Ditto.

The first immediate benefit is that we can track the token for more exact error reporting. * staptree.h (target_symbol): Add a new component type. * staptree.cxx (target_symbol::component::print): New. (operator<<(ostream&, target_symbol::component&): New. (target_symbol::print): Adapt component printing. (cast_op::print): Ditto. * parse.cxx (parser::parse_target_symbol_components): Adapt to the new component construction. * dwflpp.cxx (dwflpp::find_struct_member): take the component as a parameter for a better token in error messages (dwflpp::translate_components): Adapt to the new component type. * tapsets.cxx (dwarf_var_expanding_visitor::visit_target_symbol): Don't overwrite the token in target_symbol saved errors.
