Moved it to mupen64plus-core because it is my main concern here. There are bigger concerns (rsp+video plugins) for big endian architectures but we not talking about them here.

Not to say yea or nay - just to sync up first:
I think there was already a bug in the past to build it on more architectures.
Since I don't have the means to test it on these architectures (and some of
the code is not 100% portable), I wanted someone to test it on these
architectures and take of them in case there are problems reported - which
didn't happen. At that time, both armhf+arm64 were also not officially
supported. I have now looked in the 2.6.0 makefile and got the ARM portion:
ifneq ("$(filter arm%,$(HOST_CPU))","")
ifeq ("$(filter arm%b,$(HOST_CPU))","")
CPU := ARM
PIC ?= 1
NEW_DYNAREC := 1
ifneq ("$(filter arm64,$(HOST_CPU))","")
ARCH_DETECTED := 64BITS
$(warning Architecture "$(HOST_CPU)" not officially supported.)
else
ARCH_DETECTED := 32BITS
CFLAGS += -marm
ifneq ("$(filter armv5%,$(HOST_CPU))","")
CFLAGS += -DARMv5_ONLY
$(warning Using ARMv5_ONLY)
endif
ifneq ("$(filter armv6%,$(HOST_CPU))","")
CFLAGS += -DARMv5_ONLY
$(warning Using ARMv5_ONLY)
endif
ifeq ($(NEON), 1)
CFLAGS += -mfpu=neon -mfloat-abi=hard
else
ifeq ($(VFP_HARD), 1)
CFLAGS += -mfpu=vfp -mfloat-abi=hard
else
CFLAGS += -mfpu=vfp -mfloat-abi=softfp
endif
endif
endif
endif
endif
So arm64 is still not officially supported - also not in the current git
version. The 32 bit ones are not marked like this and could in theory be build
as an officially supported target. Since you need to manually set VFP_HARD/
NEON, do you know the debian armhf configuration? I think it was ARMv7, no-
NEON requirements and VFP_HARD. But I would need to search around to double
check this.
Of course, we can still enable arm64 builds. Upstream is not officially
supporting them, so we need someone on the Debian side to take care of it.
Kind regards,
