From 24c7957b4dbddc8545d0e0c734377746a5ae6e60 Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Thu, 17 Sep 2009 15:06:57 +0200 Subject: PR10417 Pass around attributes for supporting DW_OP_{implicit,stack}_value. 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. --- loc2c.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'loc2c.h') diff --git a/loc2c.h b/loc2c.h index 8bc59d29..becf2d85 100644 --- a/loc2c.h +++ b/loc2c.h @@ -12,7 +12,9 @@ struct location; /* Opaque */ as the starting location, begin from scratch if *INPUT is null.
