llvm-6502/Makefile.common
Chris Lattner 4bb13b8eb1 Factor platform specific makefile directives out into their own makefile
fragments.  This is gross, but having tons of confusing conditionals all
throughout the build system seems worst.

Credits got to Casey Carter for the idea.

#===-- Makefile.common - Common make rules for LLVM -------*- makefile -*--====
#
# This file is included by all of the LLVM makefiles. This file defines common
# rules to do things like compile a .cpp file or generate dependancy info.
# These are platform dependant, so this is the file used to specify these
# system dependant operations.
#
# The following functionality can be set by setting incoming variables.
# The variable $(LEVEL) *must* be set:
#
# 1. LEVEL - The level of the current subdirectory from the top of the
# MagicStats view. This level should be expressed as a path, for
# example, ../.. for two levels deep.
#
# 2. DIRS - A list of subdirectories to be built. Fake targets are set up
# so that each of the targets "all", "install", and "clean" each build.
# the subdirectories before the local target.
#
# 3. Source - If specified, this sets the source code filenames. If this
# is not set, it defaults to be all of the .cpp, .c, .y, and .l files
# in the current directory. Also, if you want to build files in addition
# to the local files, you can use the ExtraSource variable
#
#===-----------------------------------------------------------------------====
# Configuration file to set paths specific to local installation of LLVM
#
include $(LEVEL)/Makefile.config
# These are options that can either be enabled here, or can be enabled on the
# make command line (ie, make ENABLE_PROFILING=1)
#
# When ENABLE_PROFILING is enabled, the llvm source base is built with profile
# information to allow gprof to be used to get execution frequencies.
#
#ENABLE_PROFILING = 1
# When ENABLE_PURIFY is enabled, the LLVM tools are linked with purify (which
# must be locally installed) to allow for some automated memory error debugging.
#
#ENABLE_PURIFY = 1
# When ENABLE_OPTIMIZED is enabled, Release builds of all of the LLVM code are
# turned on, and Debug builds are turned off.
#
#ENABLE_OPTIMIZED = 1
# Figure out how to do platform specific stuff on this platform. This is really
# gross and should be autoconfiscated (automake actually), but should hopefully
# work on Linux and solaris (SunOS).

# When libraries are built, they are allowed to optionally define the

# from being built for the library. This .o files may then be linked to by a
# tool if the tool does not need (or want) the semantics a .a file provides
# (linking in only object files that are "needed"). If a library is never to
# be used in this way, it is better to define DONT_BUILD_RELINKED, and define
# BUILD_ARCHIVE instead.
#
# Some libraries must be built as .a files (libscalar for example) because if
# it's built as a .o file, then all of the constituent .o files in it will be
# linked into tools (for example gccas) even if they only use one of the parts
# of it. For this reason, sometimes it's useful to use libraries as .a files.
