* config/tc-sparc.c (md_pseudo_table): Change uahalf, uaword, and

[deliverable/binutils-gdb.git] / bfd / configure.host

# This file is a shell script that overrides some of the tools and
# flags used on a host specific basis.

# Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
# binutils directories (at least), the index to it is also shared.
# This is that index.  Each configure.in file should source this file
# in its per-host part.

# This sets the following shell variables:
#  HDEFINES		host specific compiler options
#  host64		set to true if this is a 64 bit host
#  HOST_64BIT_TYPE	host 64 bit type
#  SHLIB_CC		compiler to use when building shared library
#  SHLIB_CFLAGS		flags to use when building shared library
#  PICFLAG		may be set to flag to use to compile PIC
#  SHLINK		may be set to the name to link the shared library to
#  ALLLIBS		may be set to libraries to build
#  HLDFLAGS		LDFLAGS specific to the host
#  RPATH_ENVVAR		environment variable used to find shared libraries
