## The at-sign

2603 jermar 71
# The $(ATSIGN) variable holds the ASCII character representing the at-sign
2602 jermar 72
# ('@') used in various $(AS) constructs (e.g. @progbits). On architectures that
73
# don't use '@' for starting a comment, $(ATSIGN) is merely '@'. However, on
74
# those that do use it for starting a comment (e.g. arm32), $(ATSIGN) must be
75
# defined as the percentile-sign ('%') in the architecture-dependent
76
# Makefile.inc.
