# The ENV.permit_arch_flags specification is needed on 64-bit
|
|
# machines because the mlkit compiler generates 32-bit machine
|
|
# code whereas the mlton compiler generates 64-bit machine
|
|
# code. Because of this difference, the ENV.m64 and ENV.m32 flags
|
|
# are not sufficient for the formula as clang is used by both
|
|
# tools in a single makefile target. For the mlton-compilation of
|
|
# sml-code, no arch flags are used for the clang assembler
|
|
# invocation. Thus, on a 32-bit machine, both the mlton-compiled
|
|
# binary (the mlkit compiler) and the 32-bit native code generated
|
|
# by the mlkit compiler will be running 32-bit code.
