Jim Blandy	87808bd699	* dwarf2expr.h (struct dwarf_expr_context): New members 'num_pieces' and 'pieces', for returning the result of an expression that uses DW_OP_piece. (struct dwarf_expr_piece): New struct type. * dwarf2expr.c (new_dwarf_expr_context): Initialize num_pieces and pieces. (free_dwarf_expr_context): Free pieces, if any. (add_piece): New function. (execute_stack_op): Implement DW_OP_piece. * dwarf2loc.c (dwarf2_evaluate_loc_desc): If the result of the expression is a list of pieces, print an error message. (dwarf2_loc_desc_needs_frame): If the expression yields pieces, and any piece is in a register, then we need a frame.	22 years ago
Jim Blandy	99c87dab95	* dwarf2expr.c (execute_stack_op): Add 'break' statements after cases for DW_OP_div and DW_OP_shr. (Thanks to Reva Cuthbertson.)	23 years ago
Daniel Jacobowitz	b263358a72	Suggested by George Anzinger. * dwarf2expr.c (execute_stack_op): Fetch the second item from the correct stack offset. Include unknown opcode numbers in the error message.	23 years ago
Daniel Jacobowitz	bbab2f465b	* dwarf2expr.c (execute_stack_op): Don't treat the frame base as a memory pointer.	23 years ago
Elena Zannoni	c3228f1238	2003-07-22 Elena Zannoni <ezannoni@redhat.com> * findvar.c (read_var_value): Remove case for thread local storage variables. It is now entirely handled by the dwarf2 location expression code. * printcmd.c (address_info): Ditto. * symtab.h (address_class): Remove LOC_THREAD_LOCAL_STATIC enumeration value. (struct symbol): Remove objfile field, which was used by LOC_THREAD_LOCAL_STATIC only. * dwarf2read.c (decode_locdesc): Remove is_thread_local variable. * dwarf2loc.h (struct dwarf2_loclist_baton): Add comment about usage of objfile pointer. * dwarf2loc.c (locexpr_describe_location): Add case to handle thread local variables. Add include of objfiles.h. * dwarf2expr.c (execute_stack_op): Add comments about thread local storage variables. * Makefile.in (dwarf2loc.o): Update dependencies.	23 years ago

Kevin Buettner	18ec983167	* dwarf2expr.c (new_dwarf_expr_context): Set ``stack_len'' to correctly indicate an empty stack and ``stack_allocated'' to the indicate the number of elements initially allocated. (dwarf_expr_grow_stack): Simplify method for computing new stack size. Don't loop infinitely if ``stack_len'' is zero. (execute_stack_op): Move ``ctx->in_reg'' initialization out of loop. Allow DW_OP_reg0 ... DW_OP_reg31 and DW_OP_regx to be used in conjuction with DW_OP_piece. Revise error message accordingly.	24 years ago
Daniel Jacobowitz	61fbb938d6	* dwarf2expr.h (struct dwarf_expr_context): Remove extra arguments to read_reg and update its comment. Remove regnum member. * dwarf2expr.c (execute_stack_op): Remove memaddr and expr_lval. Don't call read_reg when setting in_reg. Call read_reg to get the frame base if it's in a register. Return the register number on the stack instead of in the context. Remove extra arguments to read_reg. * dwarf2loc.c (dwarf_expr_read_reg): Remove extra arguments. (dwarf2_evaluate_loc_desc): Call value_from_register. Expect the register number on the expression stack. (needs_frame_read_reg): Remove extra arguments.	24 years ago
