#
# DESCRIPTION
#
# This makefile fragment is included in more specific makefiles for
# platforms which use GNU make.
#
# PARAMETERS
#
# Assumes the following variables and definitions:
# EXTRA_TARGETS     a list of extra targets to build
# CFLAGSCOMPILER    a list of flags for all compilations
# CFLAGSCOMPILERSTRICT a list of flags for almost all compilations
# CFLAGSCOMPILERLAX a list of flags for compilations which can't be as
#                   strict (e.g. because they have to include a third-
#                   party header file that isn't -ansi -pedantic).
# CFLAGSDEBUG       a list of flags for compilations with maximum debug
#                   information, and any optimization possible
# CFLAGSOPT         a list of flags for compilations with maximum
#                   optimization, and any debug info possible
# CC                the command for the C compiler
# LINKFLAGS         a list of flags passed to the linker
# ARFLAGSPFM        platform-specific flags for ar
# RANLIB            the command to index a library (default: none needed)
# gendep  optionally defined to be a command sequence for
#         generating the dependency file (.d) from a C file (.c);
#         it is used in a rule of the form:
#           $(PFM)/$(VARIETY)/%.d: %.c
# PFM     platform code, e.g. "sus8gc"
# LIBS    extra libraries to include in tests (usually "-lm")
# NOISY   if defined and non-empty, causes commands to be emitted
# MPMPF   platform-dependent C sources for the "mpm" part
# MPMS    assembler sources for the "mpm" part (.s files)
#
# %%PART: When adding a new part, add a new parameter above for the
# files included in the part.
#
# EDITING
#
# To add new targets, varieties, and parts:
# Search for the string "%%TARGET", "%%VARIETY", or "%%PART" in this
# makefile and follow the instructions.  If you're adding a part, you'll
# have to change the makefiles for all the platforms which use this
# makefile to define the source list for that part, and the GNUmakefile
# to include a recursive call to the name of that part.
#
# CHECK PARAMETERS
#
# Old versions of GNU make don't have the $(error) function, but lines
# starting "error" cause it to exit with an error. [These only test to
# see whether the symbol is defined. We could be more thorough and
# test the syntax and content. -- richard 1995-09-07]

# THE MPS LIBRARY
#
# The MPS library is built in two ways:
#
#   1. In the usual way, from a pile of object files compiled from their
#      corresponding sources.
#
#   2. From mps.c, which effectively concatenates all the sources, allowing
#      important global optimisation and inlining to occur.
#
# We mostly use the method (2), because it is fast to compile and execute.
# But we use method (1) for some varieties to ensure correctness of
# code (linkage errors are masked by (2)) and to maintain a correct list
# of source files in case method (2) won't work on some future constrained
# platform.
#
# %%VARIETY: When adding a new variety, add a rule for how to build the
# MPS library for the variety.

# Special targets for development

# Currently FreeBSD 7 GCC 4.2.1 is the best platform we have for warning
# us about strict aliasing rule violations caused by type puns.  This
# target reveals them, and produces an assembler output file that can be
# examined to see if they're actually dangerous.  RB 2012-09-07
