config.bfd

上一个上传的有问题,这个是好的。visopsys包括系统内核和GUI的全部SOURCE code ,还包括一些基本的docs文档。里面src子目录对应所有SOURCE code.对于想研究操作系统的朋

# config.bfd
# Convert a canonical host type into a BFD host type.
# Set shell variable targ to canonical target name, and run
# using ``. config.bfd''.
# Sets the following shell variables:
#  targ_defvec		Default vector for this target
#  targ_selvecs		Vectors to build for this target
#  targ64_selvecs	Vectors to build if --enable-64-bit-bfd is given
#			or if host is 64 bit.
#  targ_archs		Architectures for this target
#  targ_cflags		$(CFLAGS) for this target (FIXME: pretty bogus)
#  targ_underscore	Whether underscores are used: yes or no

# Part of this file is processed by targmatch.sed to generate the
# targmatch.h file.  The #ifdef and #endif lines that appear below are
# copied directly into targmatch.h.

# The binutils c++filt program wants to know whether underscores are
# stripped or not.  That is why we set targ_underscore.  c++filt uses
# this information to choose a default.  This information is
# duplicated in the symbol_leading_char field of the BFD target
# vector, but c++filt does not deal with object files and is not
# linked against libbfd.a.  It is not terribly important that c++filt
# get this right; it is just convenient.
