* Fix PC arithmetic for CFI in loc2c-test.Roland McGrath2010-01-261-2/+2
| | | | * loc2c-test.c (main): Correctly bias PC passed to dwarf_cfi_addrframe.
* Report experssion stack slot use back from loc2c.Roland McGrath2009-10-141-2/+5
|
* Support DW_AT_const_value cases in loc2c and loc2c-test.Roland McGrath2009-09-241-14/+22
| | | | | | * loc2c.c (c_translate_constant): New function. * loc2c.h: Declare it. * loc2c-test.c (main): Use it for DW_AT_const_value cases.
* PR10417 Pass around attributes for supporting DW_OP_{implicit,stack}_value.Mark Wielaard2009-09-171-3/+5
| | | | | | | | | | | | | | | | | Preparation for retrieving the Dwarf_Block that holds the value of an DW_OP_implicit_value. We need the Dwarf_Attribute that is associated with the location expression operants. Depends on new elfutils 0.143 functionality. Recognizes, but does not yet handle the new operants DW_OP_{implicit,stack}_value. * loc2c.h (c_translate_location): Take an Dwarf_Attribute. * loc2c.c (c_translate_location): Likewise and pass it on. (location_relative): Likewise. (location_from_address): Likewise. (translate): Likewise and capture Dwarf_Block. * loc2c-test.c (handle_variable): Pass in Dwarf_Attribute. * dwflpp.cxx (translate_location): Likewise. (literal_stmt_for_return): Pass in NULL to indicate no attribute.
* Handle DW_TAG_reference_type in loc2c-test.Roland McGrath2009-09-161-0/+1
| | | | * loc2c-test.c (handle_variable): Handle DW_TAG_reference_type.
* Clean up loc2c-test workaround for constant DW_AT_data_member_location.Roland McGrath2009-09-161-27/+17
| | | | | | * loc2c-test.c (handle_variable): Skip the workaround for elfutils 0.142. When doing it, use a synthetic location expression. Never use c_translate_add_offset, which is broken.
* PR10533 inlined vars are not always found (lo2c-test off-by-one).Mark Wielaard2009-08-181-1/+1
| | | | | * loc2c-test.c (handle_variable): Set inner to zero after calling dwarf_getscopes_die(), for loop will increase inner.
* PR10533 loc2c doesn't resolve frame base correctly for inlined vars.Mark Wielaard2009-08-181-12/+28
| | | | | | | | | | When we see a DW_TAG_inlined_subroutine while walking the syntactical die tree as returned by dwarf_getscopes for a given variable to retrieve the frame base, then we need to switch to walking the physical die tree where the subroutine is inlined. * loc2c-test.c (handle_variable): Switch "die branches" when searching for frame base and a DW_TAG_inlined_subroutine is encountered.
* Print DIE offsets in loc2c-test scope dumps.Roland McGrath2009-08-181-1/+2

* Simplify _ELFUTILS_PREREQ checkingJosh Stone2009-08-101-2/+5
| | | | | | | We were jumping through a few hoops to deal with elfutils < 0.138 that did not have the _ELFUTILS_PREREQ macro. I've added an always-false dummy macro to take its place when it doesn't exit. All of the other "#ifdef _ELFUTILS_PREREQ" ugliness can now go away.
* Zap dwarf_diename_integrateJosh Stone2009-08-071-15/+7
| | | | | | The dwarf_diename in elfutils learned a long time ago to use dwarf_attr_integrate when looking up the name. Our minimum elfutils 0.126 has this, so we don't need to kludge it ourselves.
* Workaround cfa_nops not being needed on earlier elfutils.Mark Wielaard2009-07-231-1/+1
| | | | | * dwflpp.cxx (get_cfa_ops): Only define cfa_nops if _ELFUTILS_PREREQ(0,142). * loc2c-test.c (main): Likewise.
* Adjust to new elfutils dwarf_frame_cfa interface.Mark Wielaard2009-07-231-2/+3
| | | | | * dwflpp.cxx (get_cfa_ops): Call dwarf_frame_cfa with cfa_nops size_t. * loc2c-test.c (main): Likewise.
* Include elfutils/version.h in loc2c-test.Mark Wielaard2009-07-161-0/+3
| | | | * loc2c-test.c: Include elfutils/version.h when available.
* PR10388 Support DW_OP_call_frame_cfa.Mark Wielaard2009-07-151-4/+37
| | | | | | | | | | | | | | | | | | Depends on elfutils 0.142 cfi support. * loc2c.h (c_translate_location): Take (optional) Dwarf_Op *cfa_ops. * loc2c.c (translate): Recognize DW_OP_call_frame_cfa. (location_from_address): Take cfa_ops, examine fb_ops, if it is DW_OP_call_frame_cfa, pass cfa_ops to translate instead. (location_relative): Take cfa_ops, pass to location_from_address. (c_translate_location): Take cfa_ops, pass to location_from_address. * loc2c-test.c (handle_variable): Take cfa_ops, pass to c_translate_location when needed. (main): Fetch cfa_ops, pass to handle_variable. * dwflpp.h (struct dwflpp): Add new method get_cfa_ops. * dwflpp.cxx: Include elfutils/version.h. (translate_location): Fetch cfa_ops when necessary. (get_cfa_ops): New method.
* Add support for constant struct member field offsets.Mark Wielaard2009-07-081-4/+29

* loc2c-test resolve through const and volatile types.Mark Wielaard2009-06-241-1/+3
| | | | | * loc2c-test.c (handle_variable): Resolve through DW_TAG_const_type and DW_TAG_volatile_type typetags.
