# Compiler and flags

# ---------------------------------------------------------------------------
# GLOBAL OPTIMIZATION LEVEL
#
# Every source file in the tree is now compiled with this. Previously a number
# of files were built /NOOPTIMIZE because the DEC C++ compiler ACCVIOed on
# them; this build is a deliberate test of full optimization on real Alpha
# hardware, so all of them are back on $(OPT).
#
# To back off globally, change this ONE macro, e.g.
#     OPT = /OPTIMIZE=LEVEL=3
#     OPT = /OPTIMIZE=LEVEL=2/NOINLINE
#     OPT = /NOOPTIMIZE
# The per-file /NOOPTIMIZE fallbacks are kept as commented-out rules below, in
# case an individual file still crashes the compiler at LEVEL=4.
OPT = /OPTIMIZE=LEVEL=4
# ---------------------------------------------------------------------------
#
# ---------------------------------------------------------------------------
# INCLUDE PATHS  ($ MMK CHECK  will tell you which of these actually resolve)
#
# ONE list, $(INCDIRS), is used by EVERY compile in this file. Do not create
# per-directory variants - that duplication is what produced the invalid
# [-.-.INCLUDE] spelling and the "cannot find dosbox.h" failure.
#
# The list is a deliberate SUPERSET, so it works no matter where the headers
# live relative to the sources and no matter what the default directory is
# when the compiler runs. Both of these layouts are supported:
#
#   LAYOUT A - include as a SIBLING of the source dir (upstream layout)
#     DQB1:[000000.SRC.DOSBOX_0_72]        <- project root, holds CONFIG.H
#            +-- [.INCLUDE]                <- DOSBOX.H, CPU.H, MEM.H, ...
#            +-- [.DOSBOX_SRC]             <- this DESCRIP.MMS, DOSBOX.CPP
#                      +-- [.CPU] [.DOS] [.GUI] [.HARDWARE] [.INTS] ...
#
#   LAYOUT B - include COPIED INSIDE the source dir. This is what the
#   AlphaServer actually has, confirmed from a build log:
#     DQB1:[000000.SRC.DOSBOX_0_72.SRC]
#            +-- [.INCLUDE]                <- DOSBOX.H, CONFIG.H, CPU.H, ...
#            +-- [.CPU] [.DOS] [.GUI] ...
#   Note [-.INCLUDE] does NOT exist there, which is why the list must carry
#   [.INCLUDE] as well - the original flags only had the [-.INCLUDE] form.
#
# What each entry resolves to, with default = the source dir (DOSBOX_SRC):
#   [.INCLUDE]   -> DOSBOX_SRC.INCLUDE      (layout B)
#   [-.INCLUDE]  -> DOSBOX_0_72.INCLUDE     (layout A)
#   [--.INCLUDE] -> SRC.INCLUDE             (harmless, normally absent)
#   []           -> DOSBOX_SRC              (per-module local headers)
#   [-]          -> DOSBOX_0_72             (CONFIG.H in layout A)
#   [--]         -> SRC
#
# The [.CPU] rules SET DEFAULT [.CPU] first, which shifts everything down one
# level - [-.INCLUDE] then means DOSBOX_SRC.INCLUDE (layout B) and
# [--.INCLUDE] means DOSBOX_0_72.INCLUDE (layout A). Because both spellings
# are in the list, the SAME flags work from [.CPU] and from the source root,
# including after a failed build leaves SET DEFAULT in the wrong place.
#
# VMS SYNTAX NOTE: hyphens meaning "up a level" must be CONSECUTIVE.
# Two levels up is [--.INCLUDE]. [-.-.INCLUDE] is INVALID and will never
# find anything - do not reintroduce it.
#
# Search paths that do not exist are skipped silently by the compiler, so
# listing all of them costs nothing.
#
# ESCAPE HATCH: DOSBOX_INCLUDE is searched FIRST and is a logical name, so any
# layout can be fixed from DCL without editing this file. If MMK still cannot
# find DOSBOX.H, point it at the include directory by absolute path:
#   $ DEFINE DOSBOX_INCLUDE DQB1:[000000.SRC.DOSBOX_0_72.INCLUDE]
# An undefined logical simply fails to translate and is skipped, so leaving it
# undefined costs nothing.
#
# SDL is likewise a LOGICAL NAME, not a subdirectory - it must point at the
# SDL headers:
#   $ DEFINE SDL device:[path.SDL-1_2_14.include]
INCDIRS = (DOSBOX_INCLUDE,[.INCLUDE],[-.INCLUDE],[--.INCLUDE],[],[-],[--],SDL)
# ---------------------------------------------------------------------------
#
# Common flag groups - see the per-file rules below for which files need which.
# DECLSPEC= fixes SDL headers, SDLCALL= fixes SDL calling convention
# /name=(as_is,shortened) preserves extern "C" case to match SDL library (compiled with as_is)
DEFS = /DEFINE=(OPENVMS,__USE_STD_IOSTREAM,"DECLSPEC=","SDLCALL=")
# These warning disables prevent compiler crashes on certain constructs - but
# on a handful of files they CAUSE an ACCVIO, hence the _NOWARN variants.
WARNOFF = /WARNINGS=(DISABLE=(INTOVERFLOW,SHIFTCNTBIG,CODEUNREACHABLE))
#
# ---------------------------------------------------------------------------
# TARGET CPU ARCHITECTURE - the biggest compiler-side lever for emulator speed.
#
# WHY: the default is /ARCHITECTURE=GENERIC, which emits code that still runs
# on an EV4, and therefore MUST NOT USE the Byte/Word Extensions (BWX). Without
# BWX every single byte or word load/store becomes an LDQ_U + EXTBL (or
# LDQ_U + INSBL + MSKBL + STQ_U) sequence instead of one LDBU/STB.
#
# That matters enormously here: with C_UNALIGNED_MEMORY undefined (it must be,
# unaligned access traps on Alpha), include/mem.h implements EVERY emulated
# 16/32-bit memory access as individual byte accesses plus shifts - see
# host_readw/host_readd. Opcode fetch, memory operands and VGA writes are all
# byte traffic, so the interpreter's inner loop is dominated by exactly the
# operation GENERIC pessimises. A DS10 is an EV6/EV67 and has BWX.
#
# HOST = whatever CPU you are compiling on. The resulting binary will NOT run
# on pre-EV56 Alphas, which is fine for a DS10-targeted build. Use EV6
# explicitly if you ever cross-build.
#
# SMOKE-TEST THIS FIRST - it costs one file instead of a full rebuild:
#     $ SET DEFAULT [.SRC]
#     $ DELETE [.CPU]FLAGS.OBJ;*
#     $ MMK [.CPU]FLAGS.OBJ
# If CXX rejects the qualifier, blank the macro out and you are back to the
# previous known-good build:
#     ARCHOPT =
ARCHOPT = /ARCHITECTURE=HOST
# Further experiments, one at a time (see PERFORMANCE_TUNING_ALPHA.txt):
#     ARCHOPT = /ARCHITECTURE=HOST/OPTIMIZE=TUNE=HOST
#     OPT     = /OPTIMIZE=LEVEL=5      (adds software pipelining + unrolling)

# ---------------------------------------------------------------------------
# SETUP_CONFIG - stage CONFIG.H into the include directory, next to DOSBOX.H.
#
# WHY THIS EXISTS: include/dosbox.h does "#include ""config.h""" and is pulled
# in by essentially every source file, but CONFIG.H ships at the PROJECT ROOT
# (beside CONFIGURE.COM), not in the include directory. Nothing generates it -
# CONFIGURE.COM does not write CONFIG.H - so it must simply be in a directory
# the compiler searches. On OpenVMS the default /NESTED_INCLUDE_DIRECTORY is
# PRIMARY_FILE, meaning the quoted include inside DOSBOX.H is resolved relative
# to the .CPP being compiled (e.g. [.CPU]) and NOT relative to DOSBOX.H - so
# "it sits next to dosbox.h" is not by itself enough; the directory has to be
# in $(INCDIRS). Copying it next to DOSBOX.H puts it in a directory that is
# already proven reachable, which is why this is the reliable fix.
#
# The project root stays AUTHORITATIVE: the copy is refreshed on every build,
# so editing [-]CONFIG.H (e.g. toggling C_CORE_INLINE while performance
# testing) always takes effect and the staged copy can never go stale.
#
# DO NOT use CONFIG_VMS.H - it is stale and enables C_IPX and C_MODEM, whose
# objects (IPX.OBJ, IPXSERVER.OBJ, NULLMODEM.OBJ, SOFTMODEM.OBJ) are
# deliberately NOT in $(ALL_OBJS), so the link would fail on missing symbols.
