Subject: [PATCH 33/50] dwarf: Add missing opcodes to the operands table in
|
||
|
|
Gexpr.c
|
||
|
|
|
||
|
|
This patch adds two opcodes to the operands table in Gexpr.c, which is a mapping between opcodes and the number and types of the operands for those opcodes. Two opcodes, DW_OP_constu and DW_OP_consts are missing from this table, which caused failures later in the CFI expression parsing logic. This patch adds the missing information into the table, and thus allows correct parsing of CFA_def_cfa_expression, CFA_expression and CFA_val_expression expressions which contain the offending opcodes.
