# HISTORY
# $Log: Makefile,v $
# Revision 2.18 91/12/10 16:33:11 jsb
# New files from Intel
# [91/12/10 16:19:40 jsb]
#
# Revision 2.17 91/09/04 11:29:10 jsb
# Use cc860 for i860.
# [91/09/04 11:23:25 jsb]
#
# From Intel SSD: Added I860_CPP for i860 support.
# [91/09/02 08:57:36 jsb]
#
# Revision 2.16 91/08/24 12:32:09 af
# Added MACHINE_CFLAGS switch to support the -Wf,-XNk150 flag for
# mips string space. Apparently "danner/n3" is enough longer than
# "dbg" to exhaust string space.
# [91/08/21 danner]
# Added better cpp technology to deal with gcc limitations.
# Currently only an issue on luna88k.
# [91/07/26 danner]
# Made use of -ES vs. -E machine dependent, as luna88k does not
# like -ES.
# [91/07/19 danner]
#
# Revision 2.15.2.2 91/08/21 17:23:08 danner
# Added MACHINE_CFLAGS switch to support the -Wf,-XNk150 flag for
# mips string space. Apparently "danner/n3" is enough longer than
# "dbg" to exhaust string space.
# [91/08/21 danner]
#
# Revision 2.15.2.1 91/08/19 13:49:22 danner
# Added better cpp technology to deal with gcc limitations.
# Currently only an issue on luna88k.
# [91/07/26 danner]
# Made use of -ES vs. -E machine dependent, as luna88k does not
# like -ES.
# [91/07/19 danner]
#
# Revision 2.15 91/07/31 18:32:16 dbg
# Directly compile C files if INLINE is null (depends
# on the machine).
# Remove IBMRT-dependent fiddling for malloc.
# [91/07/30 17:32:13 dbg]
#
# Revision 2.14 91/05/14 17:55:53 mrt
# Correcting copyright
#
# Revision 2.13 91/02/14 14:19:15 mrt
# Added new Mach copyright
# [91/02/13 12:41:48 mrt]
#
# Revision 2.12 90/11/05 14:36:32 rpd
# Change MACHINE to TARGET_MACHINE.
# [90/10/29 rwd]
#
# Revision 2.11 90/09/09 14:34:39 rpd
# Remove call.o
# [90/08/24 rwd]
#
# Revision 2.10 90/06/02 15:13:30 rpd
# Compile with -DMACH_IPC_COMPAT=0.
# [90/03/26 23:29:39 rpd]
#
# Revision 2.9 90/05/29 18:40:08 rwd
# Fix PMAX_ASFLAGS.
# [90/05/22 rwd]
#
# Revision 2.8 90/05/03 15:54:28 dbg
# Use -ES switch to preprocess assembler files.
# Not all machines' 'cc' can directly assemble .s files.
# [90/04/23 dbg]
#
# Revision 2.7 90/01/19 14:36:46 rwd
# Added call.o
# [90/01/03 rwd]
#
# Revision 2.6 89/12/08 19:53:01 rwd
# Use ASFLAGS for assembler, the mips one wants to know which
# optimization level the C code was compiled at.
# [89/12/06 af]
#
# Changed CFLAGS to remove -g and add -O
# [89/10/24 rwd]
# Worked over for new merged coroutine-thread version. Removed
# task version.
# [89/10/24 rwd]
