Makefile

# Makefile — PiStorm emulator
#
# Fixes applied:
#  - Prevent 0-byte/partial binaries on failed or interrupted link:
#      * .DELETE_ON_ERROR
#      * atomic link (link to $@.tmp then mv on success)
#  - Avoid linking headers as inputs (m68kops.h no longer appears in link line)
#  - Keep generated Musashi files ordered correctly
#  - Preserve the original "nice" MAINFILES style (MAINFILES += per-line) so
#    lines can be commented out easily.
#
# Usage examples:
#   make
#   make clean; make
#   make USE_ALSA=0
#   make USE_RAYLIB=0
#   make PLATFORM=ZEROW2_64

# Build defaults live in config.mk (override there or via make VAR=...)

# Tunables: edit here instead of hunting through rule bodies.
# WARNINGS   : compiler warnings; keep strict by default.
# OPT_LEVEL  : optimisation level (-Os/-O2/-O3). Can also set O=2,3,...
# USE_GOLD   : set to 1 to prefer gold linker (if installed).
# USE_RAYLIB : set to 0 to drop raylib/DRM deps and use a null RTG backend.
# USE_ALSA   : set to 0 to drop ALSA/ahi builds and -lasound.
# USE_PMMU   : set to 1 to enable Musashi PMMU support (experimental).
# USE_EC_FPU : set to 1 to force FPU on EC/020/LC/EC040 variants (for 68881/68882 emu).
# ARCH_FEATURES : optional AArch64 feature modifiers (e.g. +crc+simd+fp16+lse).
# CPUFLAGS   : per-platform tuning defaults below; override if needed.
# RAYLIB_*   : raylib include/lib paths; adjust for custom builds.
# USE_LTO    : set to 1 to enable link-time optimisation (-flto) on build and link.
# USE_NO_PLT : set to 1 to pass -fno-plt for direct calls (glibc-specific; default off).
# OMIT_FP    : set to 1 to omit frame pointers (-fomit-frame-pointer) for perf.
# USE_PIPE   : set to 1 to add -pipe to compile steps.
