# REQUIRES: x86, zlib

# These two checks correspond to the patched values of a_sym and a_debug_sym.
# T = 0x54 - address of .text input section for this file (the start address of
#     .text is 0 by default, the size of the preceding .text in the other input
#	  file is 0x44, and the linker script adds an additional 0x10).
# S = 0x53 - offset of .debug_info section for this file (the size of
#     the preceding .debug_info from the other input file is 0x43, and the
#	  linker script adds an additional 0x10).
# Also note that the .debug_str offsets are also offset by 0x10, as directed by
# the linker script.
