2020-11-30[gdb/symtab] Fix gdb.base/vla-optimized-out.exp with clangTom de Vries1-4/+0
Consider test-case gdb.base/vla-optimized-out.exp, compiled using clang-10. GDB fails to get the size of the vla a: ... (gdb) p sizeof (a)^M Cannot access memory at address 0x6^M (gdb) FAIL: gdb.base/vla-optimized-out.exp: o1: printed size of \ optimized out vla ... The relevant DWARF looks like this: the variable a: ... <2><12b>: Abbrev Number: 5 (DW_TAG_variable) <12c> DW_AT_name : a <132> DW_AT_type : <0x189> ... has type: ... <1><189>: Abbrev Number: 10 (DW_TAG_array_type) <18a> DW_AT_type : <0x198> <2><18e>: Abbrev Number: 11 (DW_TAG_subrange_type) <18f> DW_AT_type : <0x19f> <193> DW_AT_count : <0x117> ... with the count attribute equated to the value of this artificial variable: ... <2><117>: Abbrev Number: 4 (DW_TAG_variable) <118> DW_AT_location : 10 byte block: 75 1 10 ff ff ff ff f 1a 9f \ (DW_OP_breg5 (rdi): 1; DW_OP_constu: 4294967295; DW_OP_and; DW_OP_stack_value) <123> DW_AT_name : __vla_expr0 <127> DW_AT_type : <0x182> <12b> DW_AT_artificial : 1 ... The location description of the variable is terminated with DW_OP_stack_value, which according to the DWARF spec means that "the DWARF expression represents the actual value of the object, rather than its location". However, in attr_to_dynamic_prop, we set is_reference to true: ... baton->locexpr.is_reference = true; ... and use it in dwarf2_evaluate_property to dereference the value of the DWARF expression, which causes the access to memory at address 0x6. Fix this by ignoring the baton->locexpr.is_reference == true setting if the expression evaluation has ctx.location == DWARF_VALUE_STACK, such that we get: ... (gdb) p sizeof (a)^M $2 = 6^M (gdb) PASS: gdb.base/vla-optimized-out.exp: o1: printed size of \ optimized out vla ... Tested on x86_64-linux, with gcc. Tested the following test-cases (the ones mentioned in PR26905) on x86_64-linux with clang-10: - gdb.base/vla-optimized-out.exp - gdb.base/vla-ptr.exp - gdb.mi/mi-vla-c99 gdb/ChangeLog: 2020-11-30 Tom de Vries <tdevries@suse.de> PR symtab/26905 * dwarf2/loc.c (dwarf2_locexpr_baton_eval): Add and handle is_reference parameter.

2020-11-22[gdb/testsuite] Add testcase for DW_AT_count referencing a variableGary Benson1-1/+52
Clang describes the upper bounds of variable length arrays using a DW_AT_count attribute which references the DIE of a synthetic variable whose value is specified using a DW_AT_location. GDB handles these incorrectly if the corresponding DWARF expression finishes with a DW_OP_stack_value (PR26905). This commit adds a new kfailed test to gdb.dwarf2/count.exp with the same DWARF as that generated by Clang for gdb.base/vla-optimized-out.exp, one of the failing tests. Checked on Fedora 32 x86_64, with GCC and Clang. gdb/testsuite/ChangeLog: 2020-11-22 Gary Benson <gbenson@redhat.com> PR gdb/26905 * gdb.dwarf2/count.exp: Add test for an array whose upper bound is defined using a DW_AT_count which references another DIE.
2020-10-17[gdb/testsuite] Remove hardcoded filenames in gdb.dwarf2/*.expTom de Vries1-1/+1
There's a common occurance in dwarf assembly test-cases, where a file test.exp contains: ... standard_testfile test.c test-dw.S ... The "test.c" arg can be abbreviated to ".c".

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
