# The yasm build process creates a slew of small C subprograms that
# dynamically generate files at various point in the build process. This makes
# the build integration moderately complex.
#
# There are three classes of dynamically generated files:
# 1) C source files that should be included in the build (eg., lc3bid.c)
# 2) C source files that are #included by static C sources (eg., license.c)
# 3) Intermediate files that are used as input by other subprograms to
# further generate files in category #1 or #2. (eg., version.mac)
#
# This structure is represented with the following targets:
# 1) yasm -- Sources, flags for the main yasm executable. Also has most of
# of the actions and rules that invoke the subprograms.
# 2) yasm_config -- General build configuration including setting a
# inputs listing the checked in version of files
# generated by manually running configure. These manually
# generated files are used by all binaries.
# 3) yasm_utils -- Object files with memory management and hashing utilities
# shared between yasm and the genperf subprogram.
# 4) genmacro, genmodule, etc. -- One executable target for each subprogram.
# 5) generate_license, generate_module, etc. -- Actions that invoke programs
# built in #4 to generate .c files.
# 6) compile_gperf, compile_re2c, etc. -- Actions that invoke programs that
# turn intermediate files into .c files.
