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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3705 91177308-0d34-0410-b5e6-96231b3b80d8

#===-- 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
|

|
|
# information to allow gprof to be used to get execution frequencies.
|

#
|
|
#ENABLE_PROFILING = 1

# must be locally installed) to allow for some automated memory error debugging.
