# ARMv5 EXE/DLL ABIv2 Function Like Makefile (FLM)

# Knows how to build all possible ABIV2 executables for ARM

#

#

# Feature/Binary Variation

#

# FEATUREVARIANTNAME != "" implies a product build configuration

# FEATUREVARIANT == 1 implies a .mmp defined feature variant binary

#

# By default:

#   Build all binaries in non-product builds *and*

#   Only build feature variant binaries in product builds.

#

#   test FEATUREVARIANTNAME=="" or FEATUREVARIANT==1

#

# If FEATUREVARIANTSAFE is set:

#   Only build feature invariant binaries in non-product builds *and*

#   Only build feature variant binaries in product builds.

#

#   test (FEATUREVARIANTNAME=="" and FEATUREVARIANT=="") or

#        (FEATUREVARIANTNAME!="" and FEATUREVARIANT==1)
